The order lifecycle
An Order has a defined lifecycle, each stage of which is represented by the state attribute. Additionally, when the state changes, an Event is created that represents that change. For example, when the state changes from accepted to fulfilled an order.fulfilled Event is created.
The following table lists the enumerated state values and their associated events in the approximate order they might occur in the lifecycle:
(1) When the Order... | (2) the state transitions to... | (3) and an ... event is emitted. |
​charge isn't yet capturable and could still be pending fraud review​ |
|
|
charge is capturable, but the order requires further fraud review, and, as a result, is still not ready to fulfill |
|
|
charge is capturable, has passed fraud reviewor the Denied Parties List (DPL), and is ready to fulfill |
|
|
fails because it is blocked by fraud review or the DPL​ |
|
|
is fully cancelled​ |
| NA |
is completely fulfilled or partially fulfilled and the remaining items are cancelled |
|
|
is fulfilled and the charge is fully captured or partially fulfilled with a partially captured charge and the remaining items are cancelled or the order charge is complete​ |
|
|
is fully returned or partially returned and its remaining items are cancelled or partially/fully refunded​ |
|
|
The state values for a successful Order (i.e. the happy path) are pending_payment > in_review > accepted > fulfilled > complete . As the Order moves from one state to another, the event is recorded with a timestamp in the stateTransitions hash table.
The following diagram shows the possible state values and the actions and events associated with each throughout the Order lifecycle:
An order must also pass through a fraud review. When exactly that review occurs in the order lifecycle depends on the payment method used by the customer. The different stages of the review are represented by the fraudState attribute, whose enumerated values are blocked, in_review, and passed. These various states also trigger their own corresponding Event.
