# Create Managed Signer

`POST /v2/farcaster/signer`

## 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/signer`
- Auth: HTTP bearer

Start a Farcaster connect for the logged-in profile: create a Neynar
managed signer, sign its key request with the JubJub app account, and
hand back the approval url the creator opens in their Farcaster client.
Nothing is stored until GET /signer/{signer_uuid} sees it approved, so a
creator who closes the dialog leaves nothing behind but an unapproved
signer at Neynar, which expires with its 24 h key request.
