Adwords update to V201609, now OAuth not working anymore

[gruener-f...@exito.de]

Hi,
we updated to the new Google AdWords API V201609, because we got error, that the previouse version is not supported anymore.
After updating the necessary .dlls we get now the following error:

Error" : "invalid_client", "Error_description" : "The OAuth client was not found."

So what do we need to do or change so that this will work again. There is no documentation on that!

Thanks

Hi,

This error usually occurs when the OAuth credentials were generated with incorrect scope. Could you check if the configuration details used to generate OAuth2 credentials were provided correctly? Could you try to generate the OAuth2 credentials again with the new version of the API?

Thanks,
