Orchard's Web Request Workflow activity - orchard-modules

Question

I'm currently running Orchard v1.9.3, and I would like to use Orchard's web request workflow activity to make an API call to MailChimp's API (http://developer.mailchimp.com/documentation/mailchimp/reference/lists/members/#create-post_lists_list_id_members). I was able to determine the value for the URL field should have the following form:
https://us14.api.mailchimp.com/3.0/lists/My_MailChimp_list_id/members/
Since I'm saving data to my MailChimp list, I'm going to select "PUT" for the verb drop down field. Based on MailChimp's API documentation, I was going to enter the following value in the "Headers" field:
'content-type: application/json'
MailChimp expects a JSON-formatted request, so I'm going to choose "Json" in the "Form Format" drop-down field.
The part that I'm struggling with is the "Form Values" field. According to the API docs, the data should have the following format, "'{"email_address":"urist.mcvankab+3#freddiesjokes.com", "status":"subscribed"}'". I know MailChimp expects my e-mail address in lieu of "urist.mcvankab+3#freddiesjokes.com", but I don't understand how to map the first name, last name, and email address values from my Orchard form into this Json request.

According to the documentation you linked to, the API expects a POST request. But maybe it supports PUT all the same, I don't know.
Regarding your question, you can access the submitted FORM values via the following token:
#FormSubmission.Field:MyFieldName
So for example, if the Dynamic Forms field name you used is named EmailAddress, your JSON should look something like this:
{
"email_address":"#FormSubmission.Field:EmailAddress",
"status":"subscribed"
}
PS: Kudos for using Dynamic Forms and the Web Request Activity!
