Can I create Service-Backed_Record with POST API which returns data on input parameter, How differently it works from GET API. What could be the possible I may face if I use POST API for Service-Backed_Record.

Hi [mention:7563751c440144ce94cc6795144ad27b:e9ed411860ed4f2ba0265705b8793d05] ,

You can create a Service-Backed Record using GET API only as it will return the Data.

As postAPI will return a Reaction Tree while it's called in a rule.

Thanks & let me know if you have any more queries....

I understand from [mention:a11f77a729fb4db2af76b09948583328:e9ed411860ed4f2ba0265705b8793d05] comments that, to solve the Reaction tree result in expression rule we need to change "Usage" to "Queries Data" in POST API. This could possibly resolve issue.

Correct. A "queries data" integration can be called anywhere, while a "Modifies data" can only be used in a process or saveInto. The used HTTP method does not matter.

There is no difference. The only thing is that when selecting POST as method, Appian assumes that you want to modify data in the other system. So you have to switch "Usage" back to "Queries Data".

So I can use the external system POST API as a source for my Service-Backed_Record without any issues
