| Title | Offer Mismatch |
| Recommended Status | 422 Unprocessable Entity |


## 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
