I'm making a custom connector in Microsoft Flow and I have a problem with polling trigger. If I understand the documentation correctly, the only way to create a polling trigger is to send a query parameter with timestamp. Then API respond only with new data. Am I right?
However API that I use send always all data and it has no way to send a query parameter with timestamp.
Is it possible to create a polling trigger with filtering data on connector side and not on API side?
Thank you in advance for help.
