Follow a User API | Programmatic Twitter Follow

Follow User follows an account on behalf of your own authenticated X account. It requires a registered X session, since the follow belongs to a real account, and returns ok:true when recorded. Pass the target's numeric user_id as a query parameter. This is a write action billed at $0.0008 per call, the same as a standard read.

curl -X POST "https://example.com/user/follow?user_id=44196397"

{  "ok": true}

{  "error": "bad_request",  "message": "Missing or malformed parameter. Fix the request before retrying."}

{  "error": "unauthorized",  "message": "The API key is missing, malformed, or revoked. Check the Authorization header."}

{  "error": "insufficient_credits",  "message": "Your balance is exhausted. Top up your credits to continue."}

{  "error": "forbidden",  "message": "The acting account is not authorized for this write action, or has no logged-in session."}

{  "error": "not_found",  "message": "The resource does not exist, for example a deleted tweet or a private account."}

{  "error": "rate_limited",  "message": "Too many requests. Back off and retry with exponential backoff."}

{  "error": "server_error",  "message": "Something failed on our side. Retry with backoff; if it persists, contact support."}

Pricing

Writes are billed at $0.0008 per call, the same as a standard read. A follow that fails before reaching X is not billed.

FAQ

Does Follow User need a session?

Yes. A follow is added to your own X account's graph, so you must register an X session first or the call returns session_required.

What identifier does it take?

The target account's numeric user_id as a query parameter. Resolve a handle to its ID first with User Info by Username if needed.

How do I unfollow?

Call Unfollow User (user/unfollow) with the same user_id to remove the follow from your account.
