How to do OAuth 1.0 verification with HTTP Service

Hey ya’ll, I’m working on a pet project using my schools API service, to make a planner for my assignments, but on roblox… I know, I apologize. The issue is, it requires OAuth1. I have all the proper authentication keys, and I’ve tested all the requests using https://postman.co/ so I do know what I’m doing.

If anyone could assist me, that’d be great.

TLDR: How do you do OAuth 1.0?
