States

States allow you to model finite state machines reflecting custom business logic. They are available for Orders, Line Items, Products, Reviews, Payments, QuoteRequests, StagedQuotes, and Quotes to define.

States can be combined together by defining transitions between each State. transitionState update actions are validated to ensure the transition complies with the workflow definition.

If the transitions field is not set, no validation is performed. This is useful when an external system executes the workflow and the current State is to be saved.

By default, each Project has a builtin, initial, and LineItemState defined for LineItems and CustomLineItems.

Representations

State

id​
String​

Unique identifier of the State.

version​
Int​

Current version of the State.

key​
String​

User-defined unique identifier of the State.

type​
StateTypeEnum​

Indicates to which resource or object types the State is assigned to.

name​
LocalizedString​

Name of the State.

description​
LocalizedString​

Description of the State.

initial​
Boolean​

true for an initial State, the first State in a workflow.

builtIn​
Boolean​

true for States that are an integral part of the Project. Those States cannot be deleted and their key cannot be changed.

roles​
Array of StateRoleEnum​

Roles the State can fulfill for Reviews and Line Items.

transitions​
Array of StateReference​
  • list of States of the same type that the current State can be transitioned to. For example, when the current State is the Initial State of StateType OrderState and this list contains the reference to the Shipped OrderState, the transition Initial -> Shipped is allowed.
  • if empty, no transitions are allowed from the current State, defining the current State as final for this workflow.
  • if not set, the validation is turned off and the current State can be transitioned to any other State of the same type as the current State.
createdAt​
DateTime​

Date and time (UTC) the State was initially created.

createdBy​BETA
CreatedBy​

IDs and references that created the State.

lastModifiedAt​
DateTime​

Date and time (UTC) the State was last updated.

lastModifiedBy​BETA
LastModifiedBy​

IDs and references that last modified the State.

StateDraft

key​
String​

User-defined unique identifier for the State.

type​
StateTypeEnum​

Specify to which resource or object type the State is assigned to.

name​
LocalizedString​

Name of the State.

description​
LocalizedString​

Description of the State.

initial​
Boolean​

Set to false if the State is not the first step in a workflow.

Default: true​
roles​
Array of StateRoleEnum​

If suitable, assign predifined roles the State can fulfill in case the State's type is LineItemState or ReviewState.

transitions​
Array of StateResourceIdentifier​

Define the list of States of the same type to which the current State can be transitioned to.

  • If, for example, the current State is the Initial State of StateType OrderState and you want to allow the transition Initial -> Shipped, then add the StateResourceIdentifier to the Shipped OrderState to this list.
  • Set to empty list for not allowing any transition from the current State and defining it as final State for a workflow.
  • Do not set this field at all to turn off validation and allowing transitions to any other State of the same type as the current State.

StatePagedQueryResponse

PagedQueryResult with results containing an array of State.

limit​
Int​

Number of results requested.

offset​
Int​

Number of elements skipped.

count​
Int​

Actual number of results returned.

total​
Int​

Total number of results matching the query. This number is an estimation that is not strongly consistent. This field is returned by default. For improved performance, calculating this field can be deactivated by using the query parameter withTotal=false. When the results are filtered with a Query Predicate, total is subject to a limit.

results​
Array of State​

States matching the query.

StateReference

Reference to a State.

id​
String​

Unique identifier of the referenced State.

typeId​
String​
"state"

References a State.

obj​
State​

Contains the representation of the expanded State. Only present in responses to requests with Reference Expansion for States.

StateResourceIdentifier

ResourceIdentifier to a State. Either id or key is required. If both are set, an InvalidJsonInput error is returned.

id​
String​

Unique identifier of the referenced State. Required if key is absent.

key​
String​

User-defined unique identifier of the referenced State. Required if id is absent.

typeId​
String​
"state"

References a State.

StateTypeEnum

Resource or object type the State can be assigned to.

OrderState

Used by Orders.

LineItemState

Used by LineItems and CustomLineItems in Carts and Orders.

ProductState

Used by Products.

ReviewState

Used by Reviews.

PaymentState

Used by PaymentStatus in Payments.

QuoteRequestState

Used by QuoteRequest.

StagedQuoteState

Used by StagedQuote.

QuoteState

Used by Quote.

StateRoleEnum

For some resource types, a State can fulfill the following predefined roles:

ReviewIncludedInStatistics

If a Review's state has this role its rating is taken into account for ReviewRatingStatistics. This role only applies for the ReviewState StateTypeEnum.

Return

Used by Orders in the update action transitionLineItemState. This role only applies for the LineItemState StateTypeEnum.

Resource or object types the State shall be assigned to. Must not be empty.

Example: json
{
  "action": "changeType",

Change initial State

action​

"setTransitions"
transitions​
Array of StateResourceIdentifier​

Value to set. If empty, any existing value will be removed.

Possible transformations of the current State to other States of the same type (for example, Initial -> Shipped). When performing a transitionState update action and transitions is set, the currently referenced State must have a transition to the new State.

If transitions is an empty list, it means the current State is a final State and no further transitions are allowed. If transitions is not set, the validation is turned off.

When performing a transitionState update action, any other State of the same type can be transitioned to.

Example: json
{
  "action": "setTransitions",
  "transitions": [
    {
