Description

The offer-mismatch error is returned when creating an order with a token whose offer hash does not match the submitted request. This means the fulfillmentGroups or destination sent to POST /v1/delivery/orders differ from what was originally sent to POST /v1/delivery/options when the token was generated.

Common Causes

• The shopping cart contents changed after delivery options were fetched (items added, removed, or quantities changed)
• The fulfillment group structure was modified (e.g., different SKUs, quantities, or group references)
• The destination postal code or country code was altered between fetching options and creating the order

How to Resolve

1. Re-fetch delivery options by calling POST /v1/delivery/options with the current cart and destination
2. Present the updated delivery options to the customer
3. Retry order creation with the fresh token from the new options response
