A **Fulfillment Service** is a third party warehouse that prepares and ships orders
on behalf of the store owner. Fulfillment services charge a fee to package and ship items
and update product inventory levels. Some well known fulfillment services with Shopify integrations
include: Amazon, Shipwire, and Rakuten. When an app registers a new `FulfillmentService` on a store,
Shopify automatically creates a `Location` that's associated to the fulfillment service.
To learn more about fulfillment services, refer to
[Manage fulfillments as a fulfillment service app](https://shopify.dev/apps/fulfillment/fulfillment-service-apps)
guide.
## Mutations
You can work with the `FulfillmentService` object with the
[fulfillmentServiceCreate](https://shopify.dev/api/admin-graphql/latest/mutations/fulfillmentServiceCreate),
[fulfillmentServiceUpdate](https://shopify.dev/api/admin-graphql/latest/mutations/fulfillmentServiceUpdate),
and [fulfillmentServiceDelete](https://shopify.dev/api/admin-graphql/latest/mutations/fulfillmentServiceDelete)
mutations.
## Hosted endpoints
Fulfillment service providers integrate with Shopify by providing Shopify with a set of hosted endpoints that
Shopify can query on certain conditions.
These endpoints must have a common prefix, and this prefix should be supplied in the `callbackUrl` parameter
in the
[fulfillmentServiceCreate](https://shopify.dev/api/admin-graphql/latest/mutations/fulfillmentServiceCreate)
mutation.
- Shopify sends POST requests to the `<callbackUrl>/fulfillment_order_notification` endpoint
to notify the fulfillment service about fulfillment requests and fulfillment cancellation requests.
For more information, refer to
[Receive fulfillment requests and cancellations](https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#step-2-receive-fulfillment-requests-and-cancellations).
- Shopify sends GET requests to the `<callbackUrl>/fetch_tracking_numbers` endpoint to retrieve tracking numbers for orders,
if `trackingSupport` is set to `true`.
For more information, refer to
[Enable tracking support](https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#step-8-enable-tracking-support-optional).
Fulfillment services can also update tracking information with the
[fulfillmentTrackingInfoUpdate](https://shopify.dev/api/admin-graphql/unstable/mutations/fulfillmentTrackingInfoUpdate) mutation,
rather than waiting for Shopify to ask for tracking numbers.
- Shopify sends GET requests to the `<callbackUrl>/fetch_stock` endpoint to retrieve inventory levels,
if `inventoryManagement` is set to `true`.
For more information, refer to
[Sharing inventory levels with Shopify](https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#step-9-share-inventory-levels-with-shopify-optional).
To make sure you have everything set up correctly, you can test the `callbackUrl`-prefixed endpoints
in your development store.
## Resources and webhooks
There are a variety of objects and webhooks that enable a fulfillment service to work.
To exchange fulfillment information with Shopify, fulfillment services use the
[FulfillmentOrder](https://shopify.dev/api/admin-graphql/latest/objects/FulfillmentOrder),
[Fulfillment](https://shopify.dev/api/admin-graphql/latest/objects/Fulfillment) and
[Order](https://shopify.dev/api/admin-graphql/latest/objects/Order) objects and related mutations.
To act on fulfillment process events that happen on the Shopify side,
besides awaiting calls to `callbackUrl`-prefixed endpoints,
fulfillment services can subscribe to the
[fulfillment order](https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#webhooks)
and [order](https://shopify.dev/api/admin-rest/latest/resources/webhook)
webhooks.
Access Scopes
Fields
callbackUrl:
URL -
The callback URL that the fulfillment service has registered for requests. The following considerations apply:
- Shopify queries the `<callbackUrl>/fetch_tracking_numbers` endpoint to retrieve tracking numbers
for orders, if `trackingSupport` is set to `true`.
- Shopify queries the `<callbackUrl>/fetch_stock` endpoint to retrieve inventory levels,
if `inventoryManagement` is set to `true`.
- Shopify uses the `<callbackUrl>/fulfillment_order_notification` endpoint to send
[fulfillment and cancellation requests](https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#step-2-receive-fulfillment-requests-and-cancellations),
if the fulfillment service has opted in to the fulfillment order based workflow for managing fulfillments
(`fulfillmentOrdersOptIn` is set to `true`).
fulfillmentOrdersOptIn:
Boolean! -
Whether the fulfillment service uses the [fulfillment order based workflow](https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments) for managing fulfillments.
As the migration is now finished, the `fulfillmentOrdersOptIn` property is [deprecated](
https://shopify.dev/changelog/deprecation-of-the-fulfillmentservice-fulfillmentordersoptin-field)
and is always set to `true` on correctly functioning fulfillment services.
handle:
String! -
Human-readable unique identifier for this fulfillment service.
fulfillmentServiceCreate
Creates a fulfillment service.
## Fulfillment service location
When creating a fulfillment service, a new location will be automatically created on the shop
and will be associated with this fulfillment service.
This location will be named after the fulfillment service and inherit the shop's address.
If you are using API version `2023-10` or later, and you need to specify custom attributes for the fulfillment service location
(for example, to change its address to a country different from the shop's country),
use the
[LocationEdit](https://shopify.dev/api/admin-graphql/latest/mutations/locationEdit)
mutation after creating the fulfillment service.
fulfillmentServiceUpdate
Updates a fulfillment service.
If you are using API version `2023-10` or later,
and you need to update the location managed by the fulfillment service
(for example, to change the address of a fulfillment service),
use the
[LocationEdit](https://shopify.dev/api/admin-graphql/latest/mutations/locationEdit)
mutation.
