Hi Vlad,
Thank you for getting back to us. I hope that you are doing well today.
Moving forward to your concern, i understand what you wanted to happen. You can fetch the campaign report for every account using Parallel Report Download (
https://developers.google.com/google-ads/api/samples/parallel-report-download). This Parallel download report is available for client libraries. However, since you are using Rest API, I am afraid that this parallel download is not available using REST.
Furthermore, for us to further investigate, could you please provide us the complete
request and
response logs with
request ID and
request header generated on your end? You can provide it via Reply privately to the author option. If this option is not available, then send it instead on this email address
googleadsa...@google.com. If you haven't enabled the logging yet, logging can be enabled by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link
https://developers.google.com/google-ads/api/docs/client-libs?hl=en.
If you used the Google Ads UI, what we can do is to advise you to reach out to the Google Ads Product support team via this link (
https://support.google.com/google-ads/gethelp) as they are more equipped regarding UI related issues.
