Hello Jeff, Thank u very much for your answer, i will try to give u more detailed information. As i stated before, the whole sync is taking 1,5-2h usually, right now this exception occurs after abt 1h. The point is, there is no single individual call to the API that is supposed to take a long time. Due to the nature of this application, i was not able to make API calls, passing in arrays of objects, but rather had to pass each object in a separate API-Call. Im aware of the fact, that passing in arrays, saves lots of protocol- overhead, but it would require me to rewrite parts of the application. Moreover i guess _then_ the possibilty for long individual API-Calls would increase.
However as i said, there are not really long API-Calls, im not generating reports, im just adding/deleting/modifying campaigns/ad-groups/ads/keywords. Nothing else. So i guess the duration of individual calls cant be a problem here - is there any other possible reason? I will check out the information in the link provided, thanks so far Jeff. regards, --qu On 30 Apr., 17:47, AdWords API Advisor <adwordsapiadvi...@google.com> wrote: > Hello Quaylar, > > If the individual API calls you're making taking an exceedingly long > time to complete, then yes, it's possible that the AdWords API server > is closing the connection (and this may also manifest itself as the > 502 - Bad Gateway errors).
