REST API Call with formData Parameter

Question

Parameter Value Parameter Type Data Type 
 access-token header string 
 userid header string 
 apikey query string 
 filename formData string 
 filedata formData file 
 
 Hello everyone, 
 We are trying to call a REST API (type POST) via Appian and it requires two parameters to be passed as formData type. Any ideas or suggestions on how to use this API. As of now, the smart service HTTP Query allows us to pass the header and query parameters, but none of type formData . Would appreciate your input.

You can provide form data in URL-encoded format within the Request Body text. Something like this: 
fieldname1=fieldvalue1&fieldname2=fieldvalue2 
 
Set the Content-Type (in HTTP header) to be application/x-www-form-urlencoded
