What is the InventoryShipmentReceive Mutation?

The InventoryShipmentReceive mutation is a critical API endpoint used to manage inventory adjustments during shipment receiving workflows. This update introduces mandatory idempotency keys, a feature designed to improve data integrity and prevent duplicate operations.

Why Idempotency Keys Are Important

An idempotency key ensures that repeated mutation requests with the same key will not create duplicate inventory adjustments. This feature is essential for:

  • Preventing duplicate inventory adjustments caused by network retries or multiple submissions.
  • Ensuring accurate inventory levels even under repeated requests.
  • Maintaining data integrity throughout shipment receiving workflows.

Critical Update: Idempotency Key Now Required

The idempotencyKey field is now mandatory for all InventoryShipmentReceive mutations. This is a breaking change, so all new mutation requests must include this field to function correctly.

How to Use the InventoryShipmentReceive Mutation

Below is an example of how to include an idempotency key when using the InventoryShipmentReceive mutation:

mutation inventoryShipmentReceive($input: InventoryShipmentReceiveInput!) {  inventoryShipmentReceive(    id: "gid://shopify/InventoryShipment/123"    idempotencyKey: "0199150a-0776-7c59-b03a-c7bafe3f4dfc"    lineItems: [      {        shipmentLineItemId: "gid://shopify/InventoryShipmentLineItem/789"        quantity: 10        reason: ACCEPTED      }    ]  ) {    inventoryShipment {      id    }    userErrors {      field      message    }  }}

Best Practices for Idempotency Keys

To make the most of this feature, follow these tips when generating and using idempotency keys:

  • Use UUID v7 for idempotency keys as they guarantee uniqueness and provide timestamp information for traceability.
  • Ensure the key is unique to each receiving operation. Avoid re-using idempotency keys across different workflows.
  • Remember that idempotency keys are cleared periodically for system performance. Generate fresh keys for every new request to maintain protection.

Conclusion

This update makes shipment receiving workflows more robust by preventing duplicate adjustments and maintaining accurate inventory records. Implementing idempotency keys ensures consistent data integrity, even in retry scenarios.
