To develop an app that allows users to log in, create a profile, link their X (formerly Twitter) account, and display their tweets, you’ll need to follow a clear roadmap that integrates the X API v2 for fetching tweets. Here’s how to approach it:

1. Set Up X Developer Account & API Access

1. Sign Up and Create a Developer Account:
   • Go to the X Developer Portal and register as a developer.
   • Create a project and an app within the developer portal.
2. Get API Keys and Tokens:
   • Under the App Settings in the Developer Portal, retrieve the following credentials:
     • API Key
     • API Secret Key
     • Bearer Token
     • Access Token and Access Token Secret (if needed for user authentication)
3. Set Up App Permissions:
   • In the App settings, ensure permissions are set to Read and Write (if users need to post tweets later).
   • Enable OAuth 2.0 for user authentication.

2. Set Up Backend for OAuth 2.0 Authentication

You need to let users log in to their X account securely using OAuth. Follow these steps:

1. Install Libraries for OAuth: Use a library for OAuth 2.0 in your backend. Examples:
   • Python: requests-oauthlib
   • Node.js: passport-twitter or twitter-api-v2
   • PHP: league/oauth2-twitter
2. Redirect User to X for Authentication:
   • Use the OAuth 2.0 Authorization Code Flow:
     • Redirect users to the X authorization URL.
     • After successful login, X will redirect users back to your app with an authorization code.
   • Exchange the authorization code for an access token.
   Example URL: https://api.twitter.com/oauth2/authorize?response_type=code&client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&scope=read,tweet.read,users.read
3. Store Tokens: After retrieving the access token and refresh token, securely store them in your database, associated with the user’s profile.

3. Fetch User Tweets

After the user has linked their X account, you can fetch their tweets using the X API:

1. API Endpoint for Fetching Tweets: Use the X API v2 endpoint to fetch user tweets: GET https://api.twitter.com/2/users/:id/tweets
2. Steps:
   • Retrieve the user’s X account ID using the GET /2/users/me endpoint.
   • Use the returned user_id to fetch their tweets.
   Example Request: curl -X GET \ 'https://api.twitter.com/2/users/{user_id}/tweets' \ -H 'Authorization: Bearer YOUR_ACCESS_TOKEN'
3. Display Tweets in Your App: Parse the response and display the tweets on the user’s profile page.

4. Build the App Frontend

Your app frontend should include:

1. Login & Profile Creation:
   • Use traditional methods (email/password or third-party login like Google).
   • Store user details in your database.
2. Link X Account:
   • Add a “Link X Account” button.
   • On click, redirect the user to the X OAuth authorization page.
3. Display Tweets:
   • Fetch tweets via the backend and render them dynamically on the user’s profile.

5. Handle Usage Limits

The X API v2 has usage caps, so:

• Read: Make sure you don’t exceed the limit of 100 tweets per month (as shown in your screenshot). You might need to request elevated access if required.
• Cache responses in your database to minimize repeated API calls.

6. Security and Best Practices

1. Secure API Keys:
   • Never expose your API keys or tokens on the frontend. Use a secure backend to interact with the API.
2. Protect User Data:
   • Encrypt access tokens and sensitive data.
3. Rate Limiting and Caching:
   • Implement rate-limiting logic to avoid exceeding API caps.
   • Cache tweets to reduce API calls.

Example Workflow:

1. User logs in to your app.
2. User clicks “Link X Account” and authenticates via X OAuth.
3. Your app retrieves the access token and uses it to fetch the user’s tweets.
4. Display the tweets on the user’s profile page.
