Twitter API v2 Reference

Authentication

Twitter API v2 uses OAuth 2.0 Bearer Token for app-level access and OAuth 1.0a for user-level actions.

Bearer Token (read-only access + tweet creation):

Authorization: Bearer $TWITTER_BEARER_TOKEN

Environment variable: TWITTER_BEARER_TOKEN

Core Endpoints

Get authenticated user info:

curl -s -H "Authorization: Bearer $TWITTER_BEARER_TOKEN" \
  "https://api.twitter.com/2/users/me"

Response: {"data": {"id": "123", "name": "User", "username": "user"}}

Post a tweet:

curl -s -X POST "https://api.twitter.com/2/tweets" \
  -H "Authorization: Bearer $TWITTER_BEARER_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"text": "Hello world!"}'

Response: {"data": {"id": "tweet_id", "text": "Hello world!"}}

Post a reply:

curl -s -X POST "https://api.twitter.com/2/tweets" \
