INVALID_TOKEN_HEADER while connecting to Ads API from Production website, testing website is working fine. How to find what is causing the issue?

Hi,

we are having problem when we are trying to access Adwords API from our production website statusdroid.com. When I try to connect to the API, I am getting following error message.

Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/googleads/common.py", line 1300, in MakeSoapRequest

When I recreate the same steps on our testing website testing.statusdroid.com, I am able to access the API and connect the ads to our website. We are using 2 different tokens with the same API key. I was told that we cannot use the same token on production website and testing website. However we are unable to find what is causing the issue. 

Has anyone got any ideas please what may be the problem? If you have any questions or need more information, please do not hesitate to contact me. I'll be glad for any help.

Thank you.

Hello Mirek,

INVALID_TOKEN_HEADER usually occurs when the developer token in the request is missing or invalid. Please make sure the developer token entered for production site has no typos and ensure that the developer token matches the value in the AdWords API Center. If you are still facing issues, you could share the developer token that you are using for production, the AdWords account CID for which the token is associated to and the complete SOAP logs(request and response). You could reply privately to the author while sharing. Also, please note that an approved developer token can be used to make API calls against any AdWords account(Test and Production). 

Regards,
Sai Teja, AdWords API Team.
