A Google Groups thread has reports from several Google AdWords API users that Google's report download feature is having some issues.
In short, if you use the API to download reports, you may be having issues. Minutes after issuing the request for a report, they are able to be fetched from getGzipReportDownloadUrl. Now, API users are reporting that the getGzipReportDownloadUrl is resolving to a "URL not found" error.
Jeff Posnick from the AdWords API Team said he knows the URLs do expire, but not that soon.
No, that's a new one to me. I know that the URLs eventually expire, but I don't know what the exact timeframe is for that.
Many API users are having this issue and it is likely on Google's side. One user said:
I'm actually seeing this issue quite a bit - I've just been asked to look into it because of the high number of 'URL not found' issues. What could be causing this? Too many concurrent connections / reports / logins / something?
As noted above, the URL we're getting is coming straight from getGzipReportDownloadUrl, and we're hitting the URL immediately after receiving it. We're also trying it six times before giving up, so if it were a timing issue, you'd think we'd pick it up in one of the later attempts.
Jeff Posnick from the AdWords API Team said he has filed a bug in the system. But he has not given advertisers an estimated time of when it will be fixed.
