Missing API key for Google Cloud

I'm attempting to use Google's Natural Language API for PHP, and having followed the instructions, I'm getting an error in the application I've written:

Fatal error: Uncaught Google\Cloud\Core\Exception\ServiceException: { "error": { "code": 403, "message": "The request is missing a valid API key.", "status": "PERMISSION_DENIED" } }

I've downloaded the account key file, run the export, but I get the 403 error.

I've created a symbolic link to the file in the project folder, run the export, but I get the 403 error.

I placed the export in the ".bash_profile" file, exited the terminal session, but I get the 403 error.

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, and [FILE_NAME] with the filename. This variable only applies to your current shell session, so if you open a new session, set the variable again.

When I ran: echo $GOOGLE_APPLICATION_CREDENTIALS the export isn't there, so I ran it again, but I get the 403 error.

I followed the documentation to the letter, and I've gone through it three times, and each time I get the same 403 error.

I see no instructions asking me to store a string value for the API key in the application, but I've found a number of people recommending that, but not provide an example of how or where.

So, some advice would be welcome!

simply do not use an export; while your ~/.bashrc is not apache's .bashrc.

but add the path to the file directly into the PHP code; eg. into a config.php.

or use putenv('GOOGLE_APPLICATION_CREDENTIALS=/var/www/[FILE_NAME].json');

while preventing HTTP access to that file with .htaccess.

or one can even setup with .htaccess, alike

SetEnv GOOGLE_APPLICATION_CREDENTIALS "/var/www/[FILE_NAME].json"
