PHP Quickstart

Complete the steps described in the rest of this page to create a simple PHP command-line application that makes requests to the Google Apps Script API.

Prerequisites

To run this quickstart, you need the following prerequisites:

PHP 5.4 or greater with the command-line interface (CLI) and JSON extension installed
The Composer dependency management tool
A Google account with Google Drive enabled

Step 1: Turn on the Google Apps Script API

Click this button to create a new Cloud Platform project and automatically enable the Google Apps Script API:

Enable the Google Apps Script API

In resulting dialog click DOWNLOAD CLIENT CONFIGURATION and save the file credentials.json to your working directory.

Step 2: Install the Google Client Library

composer require google/apiclient:^2.0

See the library's installation page for the alternative installation options.

Step 3: Set up the sample

Create a file named quickstart.php in your working directory and copy in the following code:

apps-script/quickstart/quickstart.php

View on GitHub

<?php
require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Apps Script API PHP Quickstart');
    $client->setScopes("https://www.googleapis.com/auth/script.projects");
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first
    // time.
    $tokenPath = 'token.json';
    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
    }

    // If there is no previous token or it's expired.
    if ($client->isAccessTokenExpired()) {
        // Refresh the token if possible, else fetch a new one.
        if ($client->getRefreshToken()) {
            $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        } else {
            // Request authorization from the user.
            $authUrl = $client->createAuthUrl();
            printf("Open the following link in your browser:\n%s\n", $authUrl);
            print 'Enter verification code: ';
            $authCode = trim(fgets(STDIN));

            // Exchange authorization code for an access token.
            $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
            $client->setAccessToken($accessToken);

            // Check to see if there was an error.
            if (array_key_exists('error', $accessToken)) {
                throw new Exception(join(', ', $accessToken));
            }
        }
        // Save the token to a file.
        if (!file_exists(dirname($tokenPath))) {
            mkdir(dirname($tokenPath), 0700, true);
        }
        file_put_contents($tokenPath, json_encode($client->getAccessToken()));
    }
    return $client;
}


/**
 * Shows basic usage of the Apps Script API.
 *
 * Call the Apps Script API to create a new script project, upload files to the
 * project, and log the script's URL to the user.
 */
$client = getClient();
$service = new Google_Service_Script($client);

// Create a management request object.
$request = new Google_Service_Script_CreateProjectRequest();
$request->setTitle('My Script');
$response = $service->projects->create($request);

$scriptId = $response->getScriptId();

$code = <<<EOT
function helloWorld() {
  console.log('Hello, world!');
}
EOT;
$file1 = new Google_Service_Script_ScriptFile();
$file1->setName('hello');
$file1->setType('SERVER_JS');
$file1->setSource($code);

$manifest = <<<EOT
{
  "timeZone": "America/New_York",
  "exceptionLogging": "CLOUD"
}
EOT;
$file2 = new Google_Service_Script_ScriptFile();
$file2->setName('appsscript');
$file2->setType('JSON');
$file2->setSource($manifest);

$request = new Google_Service_Script_Content();
$request->setScriptId($scriptId);
$request->setFiles([$file1, $file2]);

$response = $service->projects->updateContent($scriptId, $request);
echo "https://script.google.com/d/" . $response->getScriptId() . "/edit\n";

Step 4: Run the sample

Run the sample using the following command:

php quickstart.php

The first time you run the sample, it will prompt you to authorize access:

Browse to the provided URL in your web browser.

If you are not already logged into your Google account, you will be prompted to log in. If you are logged into multiple Google accounts, you will be asked to select one account to use for the authorization.
Click the Accept button.
Copy the code you're given, paste it into the command-line prompt, and press Enter.

Notes

Authorization information is stored on the file system, so subsequent executions will not prompt for authorization.
The authorization flow in this example is designed for a command-line application. For information on how to perform authorization in a web application, see Using OAuth 2.0 for Web Server Applications.

Troubleshooting

This section describes some common issues that you may encounter while attempting to run this quickstart and suggests possible solutions.

SSL certificate problem: unable to get local issuer certificate

This error indicates that the underlying HTTP libraries can't find a certificate store, and are therefore unable to setup the SSL connection to Google's servers. See the Guzzle library's documentation for information on how to setup a certificate store on your machine.

Uncaught InvalidArgumentException: missing the required redirect URI

This error occurs when the credentials.json file used contains a client ID of the wrong type. This code requires an OAuth client ID of type Other, which will be created for you when using the button in Step 1. If creating your own client ID please ensure you select the correct type.

This app isn't verified.

The OAuth consent screen that is presented to the user may show the warning "This app isn't verified" if it is requesting scopes that provide access to sensitive user data. These applications must eventually go through the verification process to remove that warning and other limitations. During the development phase you can continue past this warning by clicking Advanced > Go to {Project Name} (unsafe).
