Hi,
We are trying to access a user's AdWords report, the user has allowed us to access his AdSense & AdWords and we have the refresh token, we call the "OAuth2.refreshAccessToken" to get access token, it is OK. Then we use the access token to call AdWords API (e.g.
https://adwords.google.com/api/adwords/reportdownload/v201509), it failed with error:
<HTML>
<HEAD><TITLE>Unauthorized</TITLE></HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Unauthorized</H1>
<H2>Error 401</H2>
</BODY>
</HTML>
Our code works well for other users' refresh token, but for this user it always failed with above error, how it happens and how can we fix it?
Thanks,
