Hi AdWords API team,
There seems to be a issue with the report API, starting 3 days ago (2016-08-19).
We're getting random HTTP error 400 on (normally valid) report requests, with a generic HTML error message instead of the usual XML error details we get for invalid report definitions:
<HTML>
<HEAD>
<TITLE>Bad Request</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Bad Request</H1>
<H2>Error 400</H2>
</BODY>
</HTML>
The frequency of those errors is pretty low (on the report download jobs I checked, I found a 0.2% failure rate) but it's very inconvenient, because quite logically we don't retry for status code 400.
Are there other API users here experiencing the same issue?
API team, do you also think it's indeed a problem on the AdWords side? Thanks in advance for your feedback.
