REST POST issues

Hello, In a free app I have created a REST service(POST), it does not have authentication. When I make the call from another application, it responds with a 200 but the process does nothing and in the first step of the microflow I write in the log that it does not write either, in the cloud trace it leaves no trace.   On the other hand, when I test it from swagger with the same json, the process works correctly and writes the trace. Any clue what is happening?

If you go to swagger do you log in? Because that might be your problem. If you log into swagger then that context is used for the POST. But if you do it from another system you are anonymous. And did you then make sure that anonymous users can do all the stuff?
