So, I've got a HTTP Post that I am doing with two parameters. I'm not receiving any sort of session ID back to help me with the URL redirect. Apparently it is more of a 'post to this' and you're in. Which, I went into Postman and was able to put in the parameters and get a Status 200 OK. However, the response was HTML.
When I hit Preview in Postman it showed me the webpage that I was needing to be redirected to, essentially. How can I do a post to redirect like this within Salesforce? Is that possible or do I have to receive a session ID/cookie back to get something like this to work?
