I’m a psychology graduate student who only has experience in authorizing with OAuth 2.0 or 1.0 to pull public data using TwitteR and rtweet in R. Right now I need to require participants authorize my app by signing in to their account. I followed the following links but I don’t have the necessary knowledge to get to this point. Any help is appreciated!

1. Authentication: Authorizing a request

2. Implementing Sign in with Twitter

“This page assumes that the reader knows how to sign requests using the OAuth 1.0a protocol. If you want to know how to sign a request, read the Authorizing a request page.” (Step 1)
3. Browser sign in flow
