is it possible to setup a response using the 'if request matches' setting, so that it responds if it does NOT match?
Test 1: read Incoming Request > XML Transformer Transformed XML > Method Outgoing Response > MethodThe XML Transformer extracts the value of the element and passes it to the Method tool. In the Method tool I store this value in the Method context (via context.put(key, value), it's basically implemented like a Map). In the Method tool for the Outgoing Response I can alter the response. If I see that the input value is "dummy_msg" I know I should return a specific error message. And in the specific error message I'm including the value I've stored in the Method context, which I can access via context.get(key).The "dummy_msg" string is set in the "Multiple Responses" in the Client Tester for Response 3. The logic is that it checks Response 1 and Response 2 for the ID, and if it doesn't match it moves on to Response 3. In Response 3 I've set it to be "Always Match". In other words, it'll return this Response regardless if it matches or not. And as I've been eluding to, the message it responds with is "dummy_msg" (you can name it anything, just be sure it's the same in the script of the Method tool attached to the "Outgoing Response").Again, it's not intuitive but it should address your use case.
