I need to call an endpoint that requires the Request Header and Request Body with Content-type and content-length and some other property as well which need to End with BOUNDARY.
Request Header
POST https://www.API-URL.com/ HTTP/1.1
Host: www.API-URL.com
Content-type: multipart/mixed; boundary=BOUNDARY
Content-length: 1034
Request Body
--BOUNDARY
Content-type: application/x-www-form-urlencoded
Content-length: 141
AppVersion=1.0&AcceptLicenseAgreement=Yes&ResponseType=application/x-x-pld&VersionNumber=xxx&UserId=xxxx&Password=xxxxx
--BOUNDARY
Content-type: application/x-x-binary
Content-length: 6
020020 // This the string Data which I need to post
--BOUNDARY--
How can I implement a call to this endpoint by using HttpClient?
Thanks in advance
