  title: Dfns Approvals Webhooks API
  description: 'Representative OpenAPI description of the Dfns wallet-as-a-service and MPC key-management REST API. Covers programmable non-custodial wallets, MPC keys, transfers and transactions, signature generation, the policy engine and approvals, webhooks, permissions and authentication (including User Action Signing), service accounts, and blockchain network reads.

    Authentication uses an Authorization Bearer access token (from a service account token or a user login) plus, for sensitive mutating operations, a User Action Signature obtained via the User Action Signing challenge/complete flow and passed in the X-DFNS-USERACTION header.'
