Hi Navah,
I work with Anthony and let me provide support to your concern.
The
INVALID_TOKEN_HEADER error occurs when the developer token in the request is missing or invalid.
The common cause of this issue are:
- The developer token is not set on the request or it contains a typo.
- The namespace of the headers in the request is not correct.
With this, you need to follow the suggestion below:
- Ensure that a developer token has been set and matches the value in the AdWords API Center.
- Ensure that the headers of the request are in the namespace
https://adwords.google.com/api/adwords/cm/{version}, where {version} is replaced with the version of the API being used.
However, since you are using a third-party tool, then I would suggest to reach out to the support of that third-party tool. You can clarify to them the set up of your developer token to this third-party tool and you can provide the suggestion I provided earlier as it will help on fixing the issue.
