We’ve been slowly replacing all of our SOAP endpoints with REST endpoints inside of Salesforce. The upside of this is that they are much easier to use. The downside is that they are harder to functionally test without a bunch of work to generate session Ids. (This was made even more frustrating by a recent change that obfuscates out the session id in debug logs) So, I decided to figure out how to run a Postman request that would then store the session id and server url for later requests to use. This post will cover how to set that up and use this one request. I plan on writing more in-depth blog later about how to use Postman to test custom REST endpoints later.
