All pipeline components must implement the IPipelineComponent interface, passing an OrderForm object interface pointer between each component. If a component returns an error, the pipeline terminates execution and returns an error to the caller.
The IPipelineComponent interface defines the following methods:
| Method | Description |
|---|---|
| Execute | The entry point at which the order processing pipeline (OPP) or Commerce Interchange Pipeline (CIP) begins executing the component. |
| EnableDesign | Sets the design mode on the component. |
