X setup

Route

API v2: chunked media upload → POST /2/tweets → read-back; threads post each part as a reply to the previous.

Your app

Create an X developer app (OAuth 1.0a user context), add the callback URL below. X charges per request on paid tiers — the composer asks for a cost acknowledgement.

Redirect URI: https://a1lane.ai/oauth/x/callback. Server variables: POSTLANE_OAUTH_X_CLIENT_ID and POSTLANE_OAUTH_X_CLIENT_SECRET.

Scopes

Read and write.

Limits the engine enforces

Per-app and per-user rate limits; the engine defers on 429.

Review gate

None beyond X's paid API tiers. A listing of our assistant connector in any AI directory does not change this: directory approval is not platform approval.
