B2B - Users

Request to Link an Existing Wallet (Consent Step 1)

Starts the consent flow for gaining operating rights on a customer’s existing wallet that belongs to another merchant. A one-time code is SMSed to the customer’s phone; the customer shares it with you to approve. Complete with POST /v1/users/link/confirm.

Use this when POST /v1/users/provision returns LINK_REQUIRED. Wallets are system-wide, but originating money-out actions requires the customer’s consent to add your business as an operator.
