register_buyer

shallow

io.kifly/mcp · Verify this server

Start registering a buyer so they can be recognized across future purchases without re-entering their details. Takes the buyer's email and name and always emails a 6-digit verification code — the response is `{ verification_required: true, buyer_profile_id }` whether the email is brand new or already has an account (so this call alone never reveals which). Ask the buyer to read you the code from their inbox, then call `verify_buyer` with the same email + code to get a `buyer_token` (`kfb_live_...`). **Store that token and pass it to `checkout` on every future order** — it pre-fills the buyer's email on the secure Stripe payment link. Safe to call for a buyer you believe is new; if they already have an account, verify_buyer still recovers it.
