I want to change all signatures
from my Gmail domain. This domain has many accounts, and I need to change it from server-side
.
I’m using php
, and I started my project with:
php composer.phar require google/apiclient:2.0
I wrote one code, but when I try to update one email (like teste@mydomain.com), I receive:
{ "error": { "errors": [ { "domain": "global", "reason": "insufficientPermissions", "message": "Insufficient Permission" } ], "code": 403, "message": "Insufficient Permission" } }
My code (using API client library)
is something like:
<?php // initialize gmail function getService() { try { include_once __DIR__ . '/vendor/autoload.php'; $client = new Google_Client(); $credentials_file = __DIR__ . '/credentials/gmailAPI.json'; // set the location manually. Credential server-side $client->setAuthConfig($credentials_file); $client->setApplicationName("GmailAPI"); $client->setScopes(['https://apps-apis.google.com/a/feeds/emailsettings/2.0/']); $gmail = new Google_Service_Gmail($client); return $gmail; } catch (Exception $e) { throw new Exception($e->getMessage()); } } function updateSignature(&$gmail) { try { // Start sendAs $signature = new Google_Service_Gmail_SendAs(); // Configure Signature $signature->setSignature("Any HTML text here."); // Update account and print answer var_dump($gmail->users_settings_sendAs->update("someEmail@myDomain.com.br","someEmail@myDomain.com.br",$signature)); } catch (Exception $e) { throw new Exception($e->getMessage()); } } try { $gmail = getService(); updateSignature($gmail); } catch (Exception $e) { echo $e->getMessage(); } ?>
My credential file (gmailAPI.json) is one service account key, and I’m using Google for Work.
I created this credential using one administrator account from this domain.
My credential file is:
{ "type": "service_account", "project_id": "myProjectId", "private_key_id": "myPrivateKeyid", "private_key": "myPrivateKey", "client_email": "gmailapi@projectid.iam.gserviceaccount.com", "client_id": "myId", "auth_uri": "url", "token_uri": "url", "auth_provider_x509_cert_url": "url", "client_x509_cert_url": "url" }
Edit 1
I changed the scopes as instructed, and now my scopes are:
$client->setScopes([‘https://www.googleapis.com/auth/gmail.settings.basic‘,’https://www.googleapis.com/auth/gmail.settings.sharing‘]);
I also added permision on Google (/AdminHome?chromeless=1#OGX:ManageOauthClients) to my service account key.
I tried API explorer and it works. When i changed the scopes, the error changed to:
{ “error”: { “errors”: [ { “domain”: “global”, “reason”: “failedPrecondition”, “message”: “Bad Request” } ], “code”: 400, “message”: “Bad Request” } }
I’m using this command:
var_dump($gmail->users_settings_sendAs->update(“someEmail@myDomain.com.br”,”someEmail@myDomain.com.br”,$signature));
I tried also
var_dump($gmail->users_settings_sendAs->get(“someEmail@myDomain.com.br”,”someEmail@myDomain.com.br”));
But I received same error.

Answer
Thank You everyone.
I tried a lot of codes, and finally found one that works.
include_once __DIR__ . '/vendor/autoload.php'; // credential file (service account) $credentials_file = __DIR__ . '/credentials/gmailAPI.json'; putenv('GOOGLE_APPLICATION_CREDENTIALS='.$credentials_file); // Initialize Google Client $client = new Google_Client(); $client->useApplicationDefaultCredentials(); // scopes to change signature $client->setScopes(['https://www.googleapis.com/auth/gmail.settings.basic','https://www.googleapis.com/auth/gmail.settings.sharing']); // *important* -> Probably because delegated domain-wide access. $client->setSubject("admEmailHere@test.com"); // Initialize Gmail $gmail = new Google_Service_Gmail($client); // set signature $signature = new Google_Service_Gmail_SendAs(); $signature->setSignature("HTML code here."); // update signature $response = $gmail->users_settings_sendAs->update("admEmailHere@test.com","admEmailHere@test.com",$signature)->setSignature(); // get signature $response = $gmail->users_settings_sendAs->get("admEmailHere@test.com","admEmailHere@test.com")->getSignature(); echo json_encode($response);
I commented all code, and I used https://developers.google.com/api-client-library/php/auth/service-accounts to create it.
Atention -> You need to give permission on Gmail, and create server key (with domain-wide access).
