Integration service layers

Service method pipelines

Version:

Each service method launches a pipeline with the same name. As part of the initial pipeline being executed, one or more additional or shared pipelines can be called and executed. For example, SaveCart or SynchronizeProductArtifacts.

In Sitecore, the default pipeline arguments contain Request and Result properties, which have Properties of type dictionary, and can contain arbitrary data to be used by pipeline processors.

Commerce Connect uses the Request.Properties dictionary to store data that you need to synchronize. There are processors that read and write the custom data.

Values that are stored in Request.Properties are internal temporary data used to carry information between the processors in the pipeline. For example, the CreateOrResumePipeline includes the FindCartInEAState processor that stores the ID of the cart. This ID is then used in the RunLoadCart processor to specify the ID of the cart to be loaded.

Data read and stored in the Request.Properties dictionary is visible between processors within the pipeline.

The following table contains a description of the cart data related to the pipelines stored in the pipeline arguments Request.Properties:

Pipeline	Property name	Data description
`CreateOrResumeCart`	`CartId`	Holds the ID of the cart found in the writer processor and consumed by the reader processor in order to load the cart from the external system. Writer processor: `FindCartInEaState` Reader processor: `RunLoadCart`
`ResumeCart`	`CartSourceStateId`	Holds the ID of the cart state that the `MoveVisitorToInitialState` processor moves visitors from. Writer processor: `CheckCanBeResumed` Reader processor: `MoveVisitorToInitialState`
	`CartDestinationStateId`	Holds the ID of the cart state that the `MoveVisitorToInitialState` processor moves visitors to. Writer processor: `CheckCanBeResumed` Reader processor: `MoveVisitorToInitialState`
