 ## Payment flow
 
 1. Once the active Order has been transitioned to the ArrangingPayment state (see the [Order Workflow guide]({{< relref "order-workflow" >}})), one or more Payments are created by executing the [`addPaymentToOrder` mutation]({{< relref "/docs/graphql-api/shop/mutations#addpaymenttoorder" >}}). This mutation has a required `method` input field, which _must_ match the `code` of one of the configured PaymentMethodHandlers. In the case above, this would be set to `"my-payment-method"`.

 ## Fulfillments
 
 Fulfillments represent the actual shipping status of items in an order. Like Orders, Fulfillments are governed by a [finite state machine]({{< relref "fsm" >}}) and by default, a Fulfillment can be in one of the [following states]({{< relref "fulfillment-state" >}}):
