Getting 401 Unauthorized error while oauth request

[Vijaysinh Parmar]

Hi,

I am using test developer token for using google ads api php lib.

to get refreshtoken I am making oauth request using my test adwords account but I am getting below error,

Client error: `POST https://oauth2.googleapis.com/token` resulted in a `401 Unauthorized` response: { "error": "invalid_client", "error_description": "Unauthorized" }  and I am not getting refreshtoken.

what could be reason for this? my email id is already added as test user in api console project.

Thanks.

Hi,

Please double check if the credentials (i.e. client ID and client secret) are correct and there are no blank spaces.
