The Ultimate Guide to OAuth2 on X: Secure Auth and Token Management for Social Scheduling

We recently added user account linking to our SaaS platform, which helps technical writers, researchers, and developers generate high-quality content, from code walkthroughs and white papers to research articles.

In this article, we share a high-level overview of the OAuth2 workflow we implemented using X’s API.

Along the way, we navigated authentication flows, token management, and made some thoughtful architectural decisions, and had a lot of fun doing it.

Here’s what the full social scheduling workflow looks like:

1. User logs in and clicks “Connect X”
2. Application redirects the user to X’s authorization page.
3. User grants the application permission to access their account.
4. X redirects the user back to the application with an authorization code.
5. Application exchanges the authorization code for an access token and a refresh token.
6. Tokens are encrypted and stored in database.
7. The user selects a time slot from a calendar view.
8. Next, they provide input materials like keywords, URLs, plain text, or uploaded documents.
