cURL Put request not working?

Hi, I'm trying to do a cURL PUT request using Insert from URL to Discord's API.

I've successfully completed the PUT request using Postman, but I can't get it to work in Filemaker.

I've successfully completed GET and POST requests with Filemaker, so I know my Discord authorization is working.

Here's the url I'm using (with IDs removed):

"https://discordapp.com/api/channels/<channel_id>/messages/<message_id>/reactions/<:name:id>/@me"

Here are my curl options (with authorization removed):

--request PUT
--header "Authorization: <token>"  
--header "User-Agent: <user>"
--header "Content-Type: application/json"

I'm getting this error response:

<!DOCTYPE html>
<html lang=en>
  <meta charset=utf-8>
  <meta name=viewport content="initial-scale=1, minimum-scale=1, width=device-width">
  <title>Error 411 (Length Required)!!1</title>
  <a href=//www.google.com/><span id=logo aria-label=Google></span></a>
  <p><b>411.</b> <ins>That’s an error.</ins>
  <p>POST requests require a <code>Content-length</code> header.  <ins>That’s all we know.</ins>

The last line of the response makes me wonder if Filemaker is submitting it as POST and not PUT?

Any suggestions are appreciated!

Thanks!

I would think that the mention of POST is just an error in their documentation.

As to your headers: you will have to add a Content-length one apparently.

You also don't have to send a User-Agent so you can skip that.

Thanks Wim. Adding this solved it:

 --header "Content-Length: 0"

Curiously, I had been able to get the PUT request to work with the Base Elements plugin without a Content-Length header:

BE_HTTP_SetCustomHeader ( "Authorization" ; "<token>" ) & 
BE_HTTP_SetCustomHeader ( "Content-Type" ; "application/json" ) & 
BE_HTTP_PUTData ( "https://discordapp.com/api/channels/<channel_id>/messages/<message_id>/reactions/<emoji>/@me" ; "" )

Thanks for your help!
