Hi Hasmer,
Thank you for providing more details on your issue. I work with Mark and allow me to assist you.
From the API's perspective, the solution to the
authorization_error: Developer token is not allowed with project XXXXXXX error would be to regenerate a new Cloud Project and credentials as stated in the
guide.
However, if you wish to first learn more on the association of your current Cloud Project and credentials, then I would recommend that you reach out instead to the Google API Console support team, via this
link, for further insight and guidance. I hope this helps.
Best regards,
