Webhook

Order ship-by deadline changed

​

Fires when the shipBy deadline of a pending order moves: the buyer gave the seller more time, or the seller or CardNexus support postponed the ship date of a pre-order. Delivered to both the seller and the buyer (recipientRole). data.reason says which; switch on it so reasons added later don't break your integration.

Body

required
application/json
  • data
    Type: object
    required

    The order's new deadline and why it moved.

    Properties: 5
  • eventId
    Type: string
    required

    Idempotency key. Stable across retries of the same delivery; safe to dedupe on.

  • recipientRole
    Type: stringenum
    required

    Whether this delivery is for the seller or the buyer side of the order. The same change produces two deliveries — one to each role.

    values
    • seller

      The seller.

    • buyer

      The buyer.

  • timestamp
    Type: stringFormat: date-time
    required

    When this webhook was emitted (ISO 8601, UTC).

  • type
    const:  
    order.ship_by.changed
    required
