How do I do a SOAP request using FRENDS platform?
Soap messages are normal http messages, that contain soap messages (xml strings) as a body. Therefore you can use normal HttpRequest task and send soap message, including soap envelope, in the body.
For soap 1.2 you need to use to http headers: Content-Type: application/soap+xml
and charset=utf-8
.
full disclosure: I work in a team that made FRENDS.
