403 error when API request from authorised domain 🤨

[morceaudebois]

Hi! Not sure if this is the right place to ask but here I go. I'm trying to configure a translation system with the Cloud Translation API and would like to restrict its usage for a specific domain.

Here's my code:

$translate = new TranslateClient([
    'key' => 'my-api-key',
]);

$translation = $translate->translate('Hello world!', [
    'target' => 'fr',
]);

My key is configured as follows with only one domain (https://example.com) and its subdomains (https://*.example.com😞

My code works perfectly when I remove all the restrictions, I'm able to make requests and translate strings. Yet when I enable them and make requests from my domain, I get a 403 error as if I wasn't sending them from the right domain:

Been stuck on this for a few days and would love some help because I have no idea what I'm doing wrong. Thanks!

Hi @morceaudebois ,

I would request you to revisit this page: 

https://cloud.google.com/docs/authentication/api-keys?&_ga=2.204391952.-186264295.1700153687#http 

I believe the issue could be related to the HTTP referrers you are manually adding in the UI.

Also, have you got a chance to check the cloud audit logs to see if there are any specific errors reported on the Google Cloud end regarding this?

Kind Regards,
