How to override token_uri in service account credentials?

[jlestel]

Hi,

I'm using the Google.Apis.Auth and PubSub library with a service account JSON key.

I would like to override the default token_uri (which is https://oauth2.googleapis.com/token) to use a custom OAuth endpoint.

In the JSON file, I changed the token_uri field to my custom endpoint: http://oauth2-myglobalpsc.p.googleapis.com

When I load the credentials using GoogleCredential.FromFile(...), I can see that the token_uri field is correctly set in the parsed ServiceAccountCredential.Initializer. However, the library still calls https://oauth2.googleapis.com/token when requesting the token.

Is there a supported way to make the library use the custom token_uri specified in the JSON file? Or another way to customize the token_uri?

Thanks!

I'm not certain why you are seeing this. I've checked and we have several tests that confirm we use the provided token URL to fetch the access token. I'm not saying there's no problem, I'm saying it's not a generalized bug so we'll need a reproduction from you. Please provide a minimum but complete console application that demonstrates the problem, include the project file so we know the versions of dependencies. Thanks.

Please also share the service account JSON key (redact sensitive values, including the key itself) so we know exactly what changes you are making there.
