Getting Started with Google Cloud APIs ​

✅ Fresh -- Updated March 2026 from official Google Cloud documentation.

Purpose ​

Walk through the complete setup process for using any Google Cloud API, from creating a project to making your first API call.

Prerequisites ​

  • A Google account
  • gcloud CLI installed (install guide)
  • A web browser for the Cloud Console

Procedure ​

Step 1: Initialize the gcloud CLI ​

bash
gcloud init

Follow the interactive prompts to authenticate and select a default project.

Step 2: Create a Google Cloud Project ​

A project is the resource container and isolation boundary for all GCP resources.

bash
gcloud projects create my-api-project --name="My API Project"

Set it as your active project:

bash
gcloud config set project my-api-project

Step 3: Discover APIs in the API Library ​

Browse the API Library in the Cloud Console to find available APIs:

https://console.cloud.google.com/apis/library?project=my-api-project

Or search from the CLI:

bash
gcloud services list --available --filter="name:storage"

Step 4: Enable an API ​

bash
gcloud services enable storage.googleapis.com

Verify it was enabled:

bash
gcloud services list --enabled | grep storage

Step 5: Enable Billing ​

Paid APIs require a billing account. Link one via the Console:

https://console.cloud.google.com/billing/linkedaccount?project=my-api-project

Or use the CLI:

bash
gcloud billing accounts list
gcloud billing projects link my-api-project --billing-account=BILLING_ACCOUNT_ID

Step 6: Set Up Authentication ​

For local development, use Application Default Credentials:

bash
gcloud auth application-default login

This saves credentials that client libraries pick up automatically.

Step 7: Install a Client Library ​

Choose your language:

bash
# Python
pip install google-cloud-storage

# Node.js
npm install @google-cloud/storage

# Go
go get cloud.google.com/go/storage

# Java (Maven)
# Add to pom.xml: com.google.cloud:google-cloud-storage

Step 8: Make Your First API Call ​

Python example:

python
from google.cloud import storage

client = storage.Client()
buckets = list(client.list_buckets())
print(f"Found {len(buckets)} buckets")

curl example:

bash
curl -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  "https://storage.googleapis.com/storage/v1/b?project=my-api-project"

Verification Checklist ​

  • [ ] gcloud config get-value project returns your project ID
  • [ ] gcloud services list --enabled shows the API you enabled
  • [ ] gcloud auth application-default print-access-token returns a valid token
  • [ ] Your first API call returns data without errors
