Send a Multipart REST Request

See more REST Examples

Demonstrates Rest.FullRequestMultipart, which sends a complete multipart request using the parts configured on the object, then returns the response body as text.

Background. Each multipart part is built by selecting it with the part selector, adding its header fields, and setting its body. FullRequestMultipart then assembles and sends all configured parts as a single multipart request.
