cURL request - 400 Request couldn't be deserialized


    I'm trying to use a cURL command to post to a form endpoint, but keep getting a "400 Request couldn't be deserialized" error. Please let me know if you see anything that's amiss with my test script below:


    curl --user "APITest\API.User" --header "Content-Type: application/json" --request POST --data '{"emailAddress":""}'
