You can upload a file to a REST endpoint URL as a part of the REST API call.
To pass a file as an input to REST V2 connector, you must set the content-type to either multipart/form-data or binary in the request. When the swagger definition has Input parameter of type formData, the file boundary is added to the content of the uploaded file to indicate the start and end of the file. When the swagger definition has Input parameter of type binary, the content is generated without having the file boundary.
You must have the formData parameter of type file defined as one of input parameters in swagger. For example,
{ "name":"file",
"in":"formData",
"description":"file to upload",
"required":false,
"type":"file" }
