We currently have a requirement with this specification:
Postback, notifications are sent by our server via HTTP POST. Yourpostback handler should not return a UI, but should return a plaintext (nohtml, no quotes) "result=OK". OK can be any value that can havenumbers, letters and underscores. e.g. result=FAIL_DIGEST_MISMATCH
How can this be implemented through Outsystems? It is a third party gateway we will be integrating with.
I think you can do it with a rest expose method.
Just an output parameter in the body.
Otherwise a simple page where in the preparation you do a download of a file which is your text.
