I'm trying for long hours to make a simple HTTP Post request for one of google's REST API. (Specifically the image text predict one, using model imagetext@001)
I'm supposed to send an "access_token" in the header of the HTTP POST, but unfortunately, I can't manage to get a hold of my access_token.
In all of their guides, they use this command to obtain it: "gcloud auth print-access-token" But, I'm running the HTTP POST locally, not from the google cloud console, so I can't run this command.
I have a JSON credential file but it doesn't contain an access token.
I've searched for so long into how to obtain the access_token. The few places I've found, for example this: How can I get an oauth2 access_token using Python
Didn't work for me. This is what I got in return:
{
"error": "unsupported_grant_type",
"error_description": "Invalid grant_type: client_credentials"
}
I'm sure that I'm missing something. What is it?
