Upload media to WhatsApp cloud API

[lior I 0]

I need to upload a PDF file to the WhatsApp Cloud API.
Can someone help me translate this WhatsApp curl example to Delphi pascal?
Here is the code from the WhatsApp documentation (JPEG example):

curl -X POST \
  'https://graph.facebook.com/v15.0/FROM_PHONE_NUMBER_ID/media' \
  -H 'Authorization: Bearer ACCESS_TOKEN' \
  -F 'file=@/local/path/file.jpg;type=image/jpeg' 
  -F 'messaging_product=whatsapp'

I don't know how to translate the file parameter.

-F 'file=@/local/path/file.jpg;type=image/jpeg' 

It includes both path and file type attributes.

I use Delphi 10.3 RIO

I would try with RestDebugger first, if that is successful it may generate the right code to access the API.

curl -F emulates filling content on a web page and pressing enter.
I've not used -F before, so I am not sure if the reference 'item' in 'item=something' identifies the field to be filled, and that the right side is what it should be filled with?
