Http POST call for External API from F#

Hi Team,

I want to call external POST API from F# which has multipart form request body as below so how to do in F#?

External POST API
url : “https://”
Content-Type : Multipart/Form-data
Body :- key(file) -> value(file which is browsed)
key(secured) -> value(String)

Thanks for reading this question.

Use HttpClient to make this call.

Here, code will wait of POST API response but I don’t want to wait for that result. Can you tell me how to do that
