[HELP] OIDC Authorization Code Flow - POST format

  1. DO NOT POST YOUR CLIENT SECRET PUBLICLY. THIS IS AGAINST THE DEV TOS AND IT SHOULD BE TREATED AS A PASSWORD. I have edited your post accordingly. A code should be treated similar

  2. You need to use whatever you want that supports sending a HTTP POST request over SSL in the language you are working in. So Yes SSL Socket.

Content-Type/length are headers and are not needed for this request. I don’t see any headers in the example, and they are not required

These may help
