Send HTTP Request in a Sequence

This article applies to:

You can send an HTTP Request as part of an action sequence.

  1. Drag the HTTP Request icon onto the canvas and double-click to configure

  2. You can change the request type at the top. Then you can add your Target URL with Merge Fields ( This is the same as the HTTP POST today)
  3. You can add your query parameters that show up at the end of the URL.
    ex: FristName with Value of the Contact FirstName that is Merged into that Value field ~Contact.FirstName~
  4. We also added the ability to add info in the header
  5. Then next we added the Body Text area
  6. Now, we can test the request and response

Lastly, we have the Request that is taking all the info we filled out above and creating our request. This will give us an idea of what is happening and how the request is actually getting created which is important with merge fields.
