Is it possible to use an input or output filter via error code or status code? I am looking to only go to a final step if the record is missing or not found. returning a 404

@anithaabraham, Thank you for the response on this!

We are performing a GET request to an HTTPS endpoint to check if a record is missing in the endpoint's system. If the record is missing, however, the endpoint throws a 404 error code (with a message stating why the 404 code) instead of a simple "Missing record" message. This in turn causes the Celigo flow to error at this stage. We would like for the 404 error message to be ignored and ultimately passed to the next step in the flow.

Thank you!

CJ

@cjsell you can use this functionality:

You also would need to response map the errors or status code so you could filter or branch on it later.
