Google Cloud Console: Complete Projects, APIs & Credentials Guide

Google Developer Infrastructure Playbook

Google Cloud Console: Complete Projects, APIs & Credentials Guide

Google Cloud Console is the browser-based management environment for Google Cloud projects, APIs, credentials, IAM, billing, quotas, logs and many other developer resources. For marketers and SEO teams, it often becomes relevant when a Google integration requires an API project, OAuth client, API key or service account. This guide forms part of our wider Google playbook and connects directly with developer workflows such as the Google Search Console API.

CORE Think in projects. APIs, credentials, quotas, billing and access controls are normally configured in the context of a selected Google Cloud project.
Cloud Fundamentals

Google Cloud vs Google Cloud Console

Google Cloud is the wider cloud platform. The Cloud console is one of the interfaces used to configure and manage its projects, services and resources.

CLOUD

Google Cloud

Google Cloud is the broader collection of infrastructure, platform, database, analytics, AI, developer and management services available through Google's cloud environment.

A project can contain or enable different Google Cloud services depending on what the organisation is building.

UI

Google Cloud Console

The Cloud console is the browser interface used to select projects, enable APIs, manage credentials, configure IAM, review billing, inspect quotas, analyse logs and operate many Google Cloud resources.

Many actions are also available through APIs, command-line tools and client libraries, so the console is not the only management interface.

Project Architecture

Projects Are the Fundamental Operating Unit

Cloud projects create a boundary around resources, APIs, access policies, quotas, usage and billing relationships.

API

API Boundary

Cloud APIs are enabled for selected projects. Enabling an API in one project does not automatically enable it across every other project an organisation controls.

IAM

Access Boundary

IAM policies and inherited roles help determine which principals can perform which operations on project resources.

£

Usage & Billing Context

Project resource usage can be associated with a Cloud Billing account, while service-specific quotas and monitoring are also commonly viewed by project.

Project Identity

Project Name vs Project ID vs Project Number

These three identifiers look similar in the Cloud console but serve different purposes.

NAME

Project Name

The project name is the human-readable label used to help people recognise the project in interfaces and project lists.

GuestPost UK API Tools Human readable
ID

Project ID

The project ID is a globally unique identifier. It can be adjusted during project creation, but after the project has been created the ID is permanent.

guestpost-api-tools Permanent after creation
NUM

Project Number

Google automatically assigns a numeric project identifier. Some Google services and resource references use this project number rather than the human-readable project name.

123456789012 Google generated
Naming Warning

Do Not Put Secrets or Sensitive Information in a Project ID

Project IDs can appear in resource names, service references, logs, configuration and other technical contexts. Choose a stable descriptive ID, but do not treat it as private information.

Resource Hierarchy

Organisation → Folder → Project → Resource

Larger organisations can use a hierarchy to organise projects and apply access or policy controls at appropriate levels.

01

Organisation

The organisation resource can provide the highest common hierarchy level for projects associated with an eligible organisation environment.

02

Folder

Folders can group projects by team, environment, business unit or another meaningful organisational structure.

03

Project

Projects contain or govern service resources and provide an important boundary for APIs, permissions, quotas and billing relationships.

04

Resource

Individual services create their own resources, such as storage, compute, databases, service accounts or API-related configuration.

APIs & Services

Enable Only the APIs the Project Actually Uses

Creating a Cloud project does not mean every Google API is automatically available. Required APIs normally need to be enabled for that project.

01

Select Project

Confirm the correct project before changing API or credential settings.

02

Open API Library

Use APIs & Services to locate the Google API required by the application.

03

Enable API

Enable that service specifically for the selected project.

04

Create Authentication

Choose an API key, OAuth client or workload identity according to the API.

05

Monitor Usage

Review request metrics, errors, quota and billing where they apply.

Project Hygiene

An Enabled API Does Not Need to Remain Enabled Forever

If a project no longer uses an API, disabling the unused service can reduce unnecessary exposure and the possibility of accidental usage. Always confirm dependencies before disabling a production service.

Practical Example

How Cloud Console Fits Into the Search Console API

Cloud Console provides the developer-project layer; Search Console remains the source of authorised search property data.

1

Create Project

Create a dedicated project or select an existing project that belongs to the integration.

2

Enable Search Console API

Enable the API within APIs & Services for the selected project.

3

Configure OAuth

Set up the Google Auth platform configuration and create the suitable OAuth client for the application.

4

Authorise Search Data

The user authorises access to the Search Console property. Continue with our Search Console API guide for the API request layer.

Credentials

API Key vs OAuth vs Service Account

Choosing the wrong authentication method can create unnecessary security, access and maintenance problems.

KEY

API Key

An API key can identify the calling project or application to Google APIs that support key-based access.

Keys should be restricted to the applications and APIs that genuinely need them rather than being left broadly usable.

“Which application or project is making this supported API request?”
OAuth

OAuth Client

OAuth is used when an application needs a person to grant permission to access private Google data on that person's behalf.

The resulting access token represents the authorised scope granted to the application.

“Which user authorised this application to access their data?”
SA

Service Account

A service account is a non-human identity typically used by an application or workload rather than by an individual person.

It can receive IAM roles and authenticate workloads to supported Google Cloud resources.

“Which workload identity is performing this operation?”
API Key Security

Never Treat an Unrestricted API Key as Finished Configuration

Where an API uses keys, restrictions can reduce the damage caused if a key is copied, exposed or used from an unintended application.

KEY

Restrict Keys to Their Intended Use

API restrictions can limit which Google APIs accept the key. Application restrictions can further constrain where supported keys may be used.

A browser-facing Maps key, for example, should not automatically be treated as a general-purpose credential for unrelated APIs.

When a key is no longer required, remove it rather than keeping unused credentials indefinitely.

Restrict the API Allow the key to call only the services it genuinely needs.
Restrict the application Use appropriate website, IP, app or other supported restrictions.
Monitor usage Unexpected traffic can indicate a configuration error or credential exposure.
Rotate when required Replace old credentials carefully and remove obsolete keys after migration.
Never commit secrets Do not place private credentials inside public repositories or exposed source files.
Google Auth Platform

OAuth Lets Users Authorise Access to Private Google Data

OAuth is appropriate when an application needs delegated access to a user's Google data rather than simply identifying a project.

OAuth Is a Permission Flow, Not Just a Client ID

Current Google configuration brings OAuth-related application settings into the Google Auth platform, including areas such as Branding, Audience and Data Access.

The application creates a suitable OAuth client, sends the user to Google's authorisation flow and requests specific scopes. After consent, an access token can be used to call the permitted Google API.

This is the authentication model used by integrations such as the Search Console API when a user's private property data needs to be accessed.

1
Configure Google Auth Platform Set application information, audience and data-access settings.
2
Create OAuth Client Choose the correct client type for the application.
3
Request Authorisation Send the user through Google's OAuth consent flow.
4
Receive Access Token The token carries the authorised scope of access.
5
Call the Google API Use the token only for the resources and operations authorised.
OAuth Components

Client ID, Redirect URI, Scope and Tokens

These concepts solve different parts of the authorisation process and should not be treated as interchangeable credentials.

ID

Client ID

Identifies the OAuth application to Google's authorisation system. Different application types can require different client configurations.

URI

Redirect URI

For applicable OAuth flows, this is an authorised destination where Google returns the user's browser after the authorisation step. It needs to match the configured value.

SCOPE

Scope

Defines the resources or operations the application asks the user to authorise. Request only the scope actually required.

TOKEN

Access & Refresh Tokens

Access tokens authorise API calls for a limited period. Where the OAuth flow supports it, a refresh token can be used to obtain new access without asking the user to approve every request again.

OAuth Verification

Some User-Data Scopes Can Require Additional Review

Google classifies some OAuth scopes as sensitive or otherwise subject to additional requirements. Public applications that request user-data access may therefore need branding, policy and verification work before broad production use.

Workload Identity

Service Accounts Are for Applications and Workloads

A service account represents a non-human identity that can be granted access to Google Cloud resources.

SA

A Service Account Is Not a Shared Human Login

Service accounts are intended for workloads such as applications, automations or computing resources that need their own Google Cloud identity.

Like other IAM principals, a service account can receive roles that determine which resources and operations it can access.

Where supported, prefer managed or short-lived authentication approaches over distributing long-lived private service-account key files.

Use a dedicated identity Different workloads should not automatically share one powerful service account.
Grant only required roles A reporting workload rarely needs broad project administration.
Avoid unnecessary key files User-managed service-account keys create security and rotation responsibilities.
Prefer short-lived credentials Use managed identity or federation approaches when the workload and service support them.
Remove abandoned accounts Unused workload identities and credentials should not remain active indefinitely.
Credential Security

“Download JSON Key and Leave It on the Server” Should Not Be the Default

A service-account key is a powerful credential. Google recommends using service-account keys only when there is no viable safer alternative. Where supported, workload identity, impersonation or other short-lived credential mechanisms can reduce the risks associated with storing long-lived keys.

If a key genuinely is required, protect it like a password: do not commit it to Git, do not expose it inside a public website directory, restrict access to the file and rotate or remove it when it is no longer needed.

Identity & Access Management

IAM Answers: Who Can Do What on Which Resource?

Google Cloud access is built around principals, roles, permissions and the resources to which those roles are granted.

WHO

Principal

The identity receiving access. Examples can include a Google Account, group, service account or other supported workforce/workload identity.

ROLE

Role

A role is a collection of permissions. Granting a role gives the principal the permissions included within that role.

WHAT

Resource

The project, folder, organisation or service resource on which the role is granted. Access can also be inherited through the resource hierarchy.

VIEW

Human Analyst

Give a reporting user the specific viewing access required instead of automatically granting broad administrative control.

APP

Application Service Account

Grant only the service roles the workload needs to complete its defined operation.

ADMIN

Administrator

Reserve powerful administrative roles for people who genuinely manage projects, policies or access rather than using them as convenient defaults.

Least Privilege

Give Identities the Minimum Access They Need

Overly broad IAM roles increase the impact of mistakes, compromised accounts and leaked workload credentials.

ROLE

Use Narrower Roles

Prefer appropriate predefined or carefully designed roles instead of using Owner or broad Editor access for routine tasks.

TEAM

Separate Responsibilities

Billing, security, development and reporting teams may need different access rather than one identical role for everyone.

OLD

Remove Old Access

Revoke permissions when a person, agency, workload or integration no longer needs them.

AUDIT

Review Changes

Use IAM review and audit information to understand whether privileged access still matches operational requirements.

Cloud Billing

A Billing Account Pays for Projects — It Is Not Their IAM Parent

The billing relationship and the resource hierarchy are separate concepts. This distinction matters when assigning permissions.

PROJECT

Google Cloud Project

The project contains or governs service resources and sits within the applicable resource hierarchy.

APIs & services
IAM policies
Cloud resources
Quota usage
£

Cloud Billing Account

The linked billing account defines who pays for the project's applicable Google Cloud usage and accumulates charges and savings from linked projects.

Pays linked project usage
Can be linked to multiple projects
Has its own IAM permissions
Links onwards to a Google payments profile
Important Distinction

Billing Access Does Not Automatically Mean Project Administration

Cloud Billing accounts exist outside the project's resource hierarchy and have their own access controls. A person's billing permissions and their permissions over project resources should therefore be considered separately.

Cost Management

Use Budgets to Monitor Spending — Not as a Substitute for Architecture

Cloud Billing budgets can help teams track spend against expected levels and send alerts when configured thresholds are reached.

PLAN

Set a Budget

Choose an amount that reflects expected Cloud costs for the relevant billing scope rather than waiting for unexpected expenditure to appear on an invoice.

ALERT

Configure Alerts

Budget thresholds can notify appropriate stakeholders as actual or forecast spend approaches configured levels.

CHECK

Investigate the Cause

When spend rises unexpectedly, identify the project, service and workload responsible rather than simply increasing the budget to silence an alert.

Quotas & System Limits

Enabled Does Not Mean Unlimited

Google Cloud services can apply quotas and fixed system limits even when an API or service has been enabled successfully.

QUOTA

Quota

A quota limits resource consumption or request volume. Many quotas have default values and some can be adjusted or increased through an appropriate request.

Quotas commonly apply at project level, although exact quota scope depends on the service.

LIMIT

System Limit

A system limit is a fixed service constraint rather than an ordinary adjustable quota. Examples can include architectural limits such as maximum object sizes or other service-specific boundaries.

A system limit cannot simply be increased because the project has more budget.

VIEW

Quotas & System Limits

Use the Cloud console's quota management area to filter by service and review current limits and usage.

ALERT

Quota Alerts

For supported project-level quotas, alerts can help teams respond before important applications reach operational limits.

API

Service-Specific Quotas

Always check the limits for the actual API. For example, our Search Console API guide covers its distinct Search Analytics and URL Inspection quotas.

API Monitoring

When an Integration Stops Working, Check More Than the Code

Google API usage metrics can help distinguish application bugs from authentication, quota, service or operational problems.

REQ

Request Volume

Check whether API traffic suddenly increased, disappeared or changed from the normal usage pattern.

ERR

Error Rate

Authentication failures, permission errors, invalid requests and quota responses often tell you where to investigate next.

TIME

Latency

Changes in response time can reveal a service, network or application performance problem even when requests still succeed.

USE

Quota Usage

An application can be technically correct but still fail once a service's quota or fixed limit has been reached.

Troubleshooting Order

API Failing? Check These Before Rewriting the Integration

Confirm the correct project, enabled API, credential validity, OAuth scope or IAM access, quota state, billing requirements, request errors and service logs before assuming the application code itself is the only possible cause.

Logging & Auditing

Cloud Logging vs Cloud Audit Logs

Operational logs help explain what applications and services are doing. Audit logs provide an accountability trail for administrative and access activity.

LOG

Cloud Logging

Cloud Logging provides log storage, search, analysis and monitoring support for Google Cloud resources and other connected log sources.

Application errors
Service messages
Operational events
Troubleshooting sequences
AUDIT

Cloud Audit Logs

Audit logs record administrative activities and applicable accesses within Google Cloud resources, helping teams answer the accountability questions: who did what, where and when?

Who changed an IAM policy?
Who created or altered a resource?
When did the change happen?
Which project or resource was affected?
Credential Security

Google Cloud Credential Security Checklist

Most Cloud API security problems are easier to prevent than to repair after a credential has been exposed.

OK
Restrict API keys Limit each key to its intended services and application environment where supported.
OK
Request minimum OAuth scopes Do not ask users for broader access simply because it may be useful later.
OK
Avoid unnecessary service-account keys Prefer safer short-lived or managed identity approaches where practical.
OK
Keep secrets out of Git Never commit private keys, client secrets or tokens into public repositories.
OK
Use least-privilege IAM Grant only the roles required for the human or workload task.
OK
Remove unused credentials Old integrations should not leave working keys, clients or service accounts behind.
OK
Protect OAuth tokens Store tokens securely and revoke access when the application no longer needs it.
OK
Monitor API behaviour Unexpected usage, errors or quota consumption can indicate abuse or a broken integration.
Developer Workflow

A 10-Step Google API Integration Workflow

A repeatable setup process reduces credential confusion and makes future maintenance easier.

01

Create Project

Choose a project boundary that makes operational and security sense.

02

Name It Clearly

Use a stable project name and sensible permanent project ID.

03

Enable API

Enable only the Google service the application requires.

04

Choose Authentication

Decide between supported API key, OAuth or workload identity.

05

Configure Access

Apply OAuth scopes, IAM roles and restrictions using least privilege.

06

Configure Billing

Link an active billing account when the chosen service requires it.

07

Check Quotas

Understand request and resource limits before production traffic begins.

08

Build Integration

Use the supported API, SDK or client library appropriate to the service.

09

Monitor

Watch request volume, errors, latency, logs, quota and relevant costs.

10

Clean Up

Disable obsolete APIs and remove credentials and access no longer required.

Google Ecosystem

Where Cloud Console Appears in Our Google Playbook

Cloud Console is often the infrastructure behind another Google product rather than the final tool the marketer or user interacts with.

MAP

Google Maps Platform

Maps Platform development commonly involves Cloud projects, enabled APIs, credentials, billing and quota controls. See our planned Google Maps Platform guide.

AI

Google AI Development

Google's AI development ecosystem can intersect with projects, APIs, billing and developer credentials. Continue next with Google AI Studio.

Project Organisation

Consider Separating Testing and Production

Separate projects can create cleaner boundaries for credentials, quotas, billing, permissions and experimental changes when an application becomes important enough to justify them.

DEV

Development

A development project can contain experimental APIs, temporary credentials and testing workloads without mixing every change into the production environment.

PROD

Production

Production can use more tightly governed identities, APIs, budgets and monitoring suited to the live application.

WHY

Why Separate?

The separation can reduce accidental cross-environment changes and make permissions, billing and operational ownership easier to understand.

Avoid These Errors

Common Google Cloud Console Mistakes

Most Cloud setup problems come from weak project organisation, excessive permissions, exposed credentials or confusion between authentication, billing and IAM.

ID

Choosing a Bad Permanent Project ID

The project ID cannot simply be renamed after creation. Choose a stable identifier rather than a temporary name such as “test-final-new-2”.

SECRET

Putting Sensitive Data in Project IDs

Project identifiers can appear in technical references. They should not contain passwords, client data or confidential business information.

KEY

Using Unrestricted API Keys

An unrestricted key can often be used from more locations or against more services than the original application intended.

OWNER

Making Everyone an Owner

Broad project administration should not be the default solution whenever a user needs one narrow permission.

JSON

Downloading Service Keys by Habit

Long-lived service-account keys create security responsibilities. Use them only when a safer authentication option is not viable.

GIT

Committing Credentials to Git

Client secrets, private keys, access tokens and other credentials should not be stored in publicly accessible repositories.

£

Confusing Billing With IAM

A billing relationship determines who pays for applicable usage; it does not replace the project's resource access policy.

MAX

Ignoring Quotas Until Production Fails

Understand the service's quota model before launching a workload that needs high request volume.

OLD

Leaving Old APIs & Credentials Active

Retired integrations should not leave unnecessary APIs, clients, keys or privileged service accounts behind indefinitely.

Cloud Console Questions

Common Questions About Google Cloud Console

Quick answers covering projects, API credentials, OAuth, service accounts, IAM, billing, quotas and logging.

01 What is Google Cloud Console?

Google Cloud Console is the browser-based interface for managing Google Cloud projects, APIs, resources, credentials, IAM, billing, quotas, logs and many other Cloud settings.

02 What is a Google Cloud project?

A project is a fundamental Google Cloud operating unit used to organise resources and provide context for APIs, IAM policies, quotas, usage and billing relationships.

03 Can I change a Google Cloud project ID later?

You can choose or edit the project ID during project creation, but once the project has been created the project ID is permanent. The human-readable project name is a separate concept.

04 What is the difference between an API key and OAuth?

An API key identifies a project or application to APIs that support key-based access. OAuth is used when an application needs a user to authorise access to private Google data on their behalf.

05 What is a service account?

A service account is a non-human Google Cloud identity generally used by an application or workload. It can receive IAM roles and authenticate to supported Google Cloud resources.

06 What is Google Cloud IAM?

Identity and Access Management controls which principals can use which permissions on Google Cloud resources. Access is commonly granted by binding principals to roles on resources.

07 Is a billing account the parent of a Google Cloud project?

No. A Cloud Billing account pays for usage associated with linked projects, but billing accounts exist outside the project's resource hierarchy. Billing access and project-resource access should therefore be managed separately.

08 What is the difference between a quota and a system limit?

A quota controls the amount of a resource or request volume that can be consumed and may sometimes be adjustable. A system limit is a fixed service constraint that cannot simply be increased through an ordinary quota request.

09 Should I download a service-account JSON key?

Only when it is genuinely required. Google recommends using service-account keys only when there is no viable alternative. Managed, short-lived or federated authentication can reduce the security risks of long-lived key files where supported.

10 What are Cloud Audit Logs used for?

Cloud Audit Logs record administrative activity and applicable resource access, helping organisations investigate who performed an action, what they did, where it occurred and when it happened.

Build the Cloud Foundation Correctly — Then Build the Integration

Google Cloud Console becomes far easier to manage once each layer has a clear purpose. The project provides the operating boundary. APIs & Services control which Google services are enabled. Credentials establish how applications identify or authenticate themselves. OAuth delegates user access, while service accounts provide non-human workload identity. IAM determines which principals can perform which actions. Billing determines who pays for applicable usage, while quotas and system limits control consumption. Monitoring and logs then help explain what the integration is actually doing. Use narrow permissions, restricted credentials, sensible project boundaries and regular cleanup so the Cloud environment remains understandable long after the first API call succeeds.
