X.com App only authentication and OAuth 2.0 Bearer Token

See more X Examples

Demonstrates how to obtain an X.com OAuth2 token for application-only authentication.

This allows you to issue authenticated requests on behalf of the application itself (as opposed to on behalf of a specific user). You don’t have the context of an authenticated user and this means that any request to API for endpoints that require user context, such as posting Tweets, will not work.

Your app will be able to, for example:

• Pull user timelines;
• Access friends and followers of any account;
• Access lists resources;
• Search in Tweets;

And it will not be able to:

• Post Tweets or other resources;
• Connect to Streaming endpoints;
• Search for users;
• Use any geo endpoint;
• Access Direct Messages or account credentials;
