We are having an issue using our Developer Token to access a production
AdWords account for uploading offline conversions. When we test our script
using an Authorisation Code that was generated using our AdWords Test
Account, the authorisation is successful and the upload only fails at a
later step as offline conversions can't be uploaded to test accounts.
However, when we try to test against our production account, we get the
Client error: `POST https://www.googleapis.com/oauth2/v4/token` resulted in
a `400 Bad Request` response:
"error_description": "Invalid code."
The error type returned by the API is
We have checked, and our Developer Token definitely has the "Basic access"
access level, meaning we should be able to access productions accounts. We
have tried generating the authorisation token from both our manager
account, and directly from the AdWords account that we are trying to upload
Could you please advise on what could be causing this issue? Any help would
be greatly appreciated.
