Collections Messages

My question:
Hello good day, the reason for this message is to request your support to know how I can filter salid messages when running a complete collection of webservices?, that is: I run a collection of several webservices, however when validating the outputs (response) it presents me only the codes (200, 404, etc), what really interests me beyond the codes is the message for example if I expect a “response” with code 200 Ok and the text is “Hello World”, how can I get the message “Hello World” and export this message to a file?, Please. I appreciate your support in advance.

I don’t know how to export the message to the file.
But, if you just need to check the status 200 OK should have the message “Hello world”, then you can use the if statement to do this check.
