This page shows how to get started with the Google APIs Client Libraries for the Cloud IAP API. Read more about the client libraries for Cloud APIs in Client Libraries Explained.
Installing the client library
PHP
For more information, see Using PHP on Google Cloud.
composer require google/apiclient
Setting up authentication
To run the client library, you must first set up authentication by creating a service account and setting an environment variable. Complete the following steps to set up authentication. For other ways to authenticate, see the GCP authentication documentation.
Cloud Console
-
In the Cloud Console, go to the Create service account key page.
Go to the Create Service Account Key page - From the Service account list, select New service account.
- In the Service account name field, enter a name.
From the Role list, select Project > Owner.
- Click Create. A JSON file that contains your key downloads to your computer.
Command line
You can run the following commands using the Cloud SDK on your local machine, or in Cloud Shell.
-
Create the service account. Replace NAME with a name for the service account.
gcloud iam service-accounts create NAME
-
Grant permissions to the service account. Replace PROJECT_ID with your project ID.
gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:NAME@PROJECT_ID.iam.gserviceaccount.com" --role="roles/owner"
-
Generate the key file. Replace FILE_NAME with a name for the key file.
gcloud iam service-accounts keys create FILE_NAME.json --iam-account=NAME@PROJECT_ID.iam.gserviceaccount.com
Provide authentication credentials to your application code by
setting the environment variable GOOGLE_APPLICATION_CREDENTIALS
.
Replace [PATH] with the file path of the JSON file that contains your
service account key. This variable only applies to your current shell session,
so if you open a new session, set the variable again.
Linux or macOS
export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
For example:
export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/my-key.json"
Windows
With PowerShell:
$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
For example:
$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\my-key.json"
With command prompt:
set GOOGLE_APPLICATION_CREDENTIALS=[PATH]
