A question from @epkpej was asked on another of my Articles
Using the REST Generator (Response Content) in Workflow 7.6 https://www.symantec.com/connect/articles/using-rest-generator-response-content-workflow-76
They wanted to get the "Response Header" from a POST Request.
Unfortunately this isn't possible using the REST Generator. It isn't exposed in the components that are generated by the tool.
Please vote on the Idea/Feature Request:
As an alternative you can swap to a Code (Script) Component
Now we need to add a couple of Inputs
1. Inputs
2. Result Variable
3. Source Code
Namespaces
Now for the code
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL); request.Method = "GET"; request.ServicePoint.Expect100Continue = false; request.ContentType = "application/json"; using (WebResponse response = request.GetResponse()) { using (StreamReader reader = new StreamReader(response.GetResponseStream())) { //responseString = reader.ReadToEnd(); string header = response.Headers[HeaderValue]; return header; } }
As you can see the URL is being used in the first line
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
And the Header in a few down
string header = response.Headers[HeaderValue];
This makes the code a little more resuable but there is lots more you can do.
4. Test Page
Now we need an API to test
https://swapi.co/
If we test it in Postman
https://swapi.co/api/people/1
There are a number we can chose from, lets use Etag.
Now you might wish to return the collection of headers and loop through them and find the value you wish either in code or with other WF components.

If you do need to work with REST the Generator should cover most scenarios and I've written a set of Articles:
