## API Updates for May 9, 2024

**API**

* The REST Management API’s [Update a checkout](/developer/api-reference/rest/admin/management/checkouts/consignments/update-checkout-consignment) endpoint allows you to add a custom shipping method to the consignment ID. This feature allows you to create a manual order using this shipping method.

**Bug Fixes**

* We corrected our [authentication](/developer/docs/storefront/guides/customer-authentication/customer-login) documentation because the Customer login API had the wrong information for token creation. Users need store-level access to create a token. You must install the app on the store before creating a JWT.

* Added missing `order_level_refund_amount` field to the [Create a refund quote](/developer/api-reference/rest/admin/management/order-operations/payment-actions/create-order-refund-quotes) response.

* Clarified the relation between the amounts needed to complete the refund in the [Create refund quote](/developer/api-reference/rest/admin/management/order-operations/payment-actions/create-order-refund-quotes) endpoint.
