Hi. I have a test class that makes a mock REST API callout . Now,I need to make another callout in test class and the response body would be response received from first mock callout. The first callout is made and correct response is returned . However,I am unable to use the response returned as body for another mock callout. This comes out to be null. How can I accomplish this? Has anyone encountered a scenario like this.
