Hi Marcelo, 

nice to meet you! Can you describe your use case in more detail? :-) Why don’t you want to use webhooks? 

Hello, what you can do is to do a data pool write back in the first action Flow. And then build a trigger for the second Action Flow based on the write back table from the first Action Flow.

Otherwise if you dont want to write back into data pool, store it in Sharepoint and read it out with the second Action Flow

Kind regards Jonas
