# Connect Fid

`POST /v2/farcaster/connect-fid`

## Request

- Base URL: `https://api.jubjubapp.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.jubjubapp.com/v2/farcaster/connect-fid`
- Auth: HTTP bearer

Connect a Farcaster FID for INBOUND auto-tokenise, directly from the
mini-app's SIWE-verified context — no SIWN redirect, no signer.

Cast delivery depends only on the FID being present in the Neynar webhook's
author_fids filter (sync_farcaster_webhook_authors) + an active credential
row (fid -> profile_id); SIWN's signer is only needed for OUTBOUND
publishing. This endpoint creates the inbound-only credential and syncs the
filter. Auth is the mini-app jj_ session token (get_current_user), NOT the
Firebase cookie the SIWN callback uses.
