Overview

Create payout details (bank account) for a vendor. Each vendor can have at most one payout detail.

Example: Set up ACH payment details for a vendor so they can receive payouts.

Important Behaviors

• 1:1 constraint: Returns 409 if the vendor already has payout details configured.
• Routing number validation: Must be exactly 9 digits and pass ABA checksum validation.
• Masked in responses: Routing and account numbers are masked (only last 4 digits shown) in all API responses.
• Defaults to disabled: payout_method_status defaults to disabled. Must be explicitly enabled and authorized before payouts can be processed.
• Webhook: Triggers the vendor_payout_detail.created webhook event.
