Hi @Anonymous ,
Could you please share a screenshot about your flow's configuration?
Do you mean that the HTTP Request Call takes over 16 hours without any response?
Further, could your please share a bit more about the API response? It would include large data?
Currently, I could not reproduce your issue on my side, and I think it is not possible within Microsoft Flow. Currently, within Microsoft Flow (Power Automate), there is an known limit with the single outgoing Request -- The maximum value of Request Timeout for synchronous calls is 120 seconds. If you have reached this limits in your flow, you would get a time out error.
Please check the following article for more details about the known limits with the HTTP Request:
https://docs.microsoft.com/en-us/power-automate/limits-and-config#request-limits
Please consider take a try to configure the "Settings" of the "HTTP" action in your flow, then turn on the "Pagination" option, set the Threshold property to 100000 (maximum value), then click "Done", try your flow again, check if the issue is solved.
then check if the issue is solved.
If the issue still exists, please consider submit an assisted support ticket through the following link:

Best regards,
