As we talked about before, I do things a very similar way. I have never encountered this but I am concerned that might just be luck, so keen for you to get to the bottom of it!
Is there any indication which rate you're in excess of? There is a requests-per-minute rate and an operations-per-minute (probably others too). Looking at the raw XML, is your batched request to AdGroupCriterionService structured like the following? Not sure if you use a client library or not but could it be splitting up the request under the covers in an unexpected way? <SOAP-ENV:Body> <mutate xmlns="https://adwords.google.com/api/adwords/cm/v201406"> <operations xsi:type="AdGroupCriterionOperation"> <operator>ADD</operator> <operand xsi:type="BiddableAdGroupCriterion"> .... </operand> </operations> <operations xsi:type="AdGroupCriterionOperation"> <operator>ADD</operator> <operand xsi:type="BiddableAdGroupCriterion"> .... </operand> </operations> (x2000) </mutate> </SOAP-ENV:Body> </SOAP-ENV:Envelope> -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
