Sometimes it works, but most of the time it is error 404

I am trying to connect the bubble to the postmark. I want to know whether the contact opened an email, clicked on it, etc…


This is my bubble setup.


This is my postmark setup.

For whatever reason, when I run tests in postmark, I am getting error 404. Almost every time. 3 times it happened it was successful, without changing anything. What could cause this?

THANK YOU!

Set This workflow canbe run without authentication or add authentication in postmark with API Key

Actually, the problem was quite stupid. When I wanted to detect call, I clicked detect data, copied the link, closed the popup and tried to initiallize the call.

My mistake was that I should have kept the DETECT DATA popup open in order to detect data.

Thank you for your reply :slight_smile:
