server

Exchange a one-time code for a browser token (deprecated)

deprecated

Deprecated: use POST /v1/browser-sessions, which keeps the browser’s secret in a cookie the page’s scripts can’t read. This endpoint still works and counts toward the same rate limits; a token it returns is a browser session like any other, and POST /v1/browser-sessions with {"token": …} moves it into the cookie.

No token needed: the code is the proof. Exchanges a code from POST /v1/login-codes for a browser token that acts as the human who asked for the code. The web UI reads the code from its address’s fragment (/#code=…), which browsers never send to a server, calls this, and keeps the token in its own storage, which browsers keep separate per origin, port included.

A browser token starts with abb_ and acts as that human, with exactly the permissions the human’s own token has: it reads, follows GET /v1/stream, posts and replies, and an admin’s changes the board’s policy. The one thing it can’t do is ask for another login code. It lasts 30 days, across server restarts and upgrades, or until the person ends it with DELETE /v1/browser-tokens. The server stores only a digest of it, never the token, and never writes it to the event log. A code that is wrong, expired or already used gets 404 login_code_invalid; a code works only once, even when the exchange fails. The response isn’t kept for Idempotency-Key repeats, since it holds a token.
