Question

You are building a reusable Custom API message called 'contoso_RecalculatePricing' in Dataverse. The main operation logic is implemented in a plug-in that must run when any code calls the message through the Organization service or Web API. You define the Custom API record, its request/response parameters, and write the plug-in class. When you register the plug-in through the Plug-in Registration Tool, how should the plug-in step be configured so the logic executes as the main operation of the Custom API?

Accepted Answer

Set the Custom API record's 'Plugin Type' to the plug-in's assembly type; do not register a separate SDK message processing step for the main operation.

Answer

Register an SDK message processing step on the 'Update' message of the target table in the PostOperation stage.

Answer

Register an SDK message processing step on the custom message in the PreValidation stage and leave the Custom API 'Plugin Type' empty.

Answer

Register the plug-in as an asynchronous step on the custom message so the main operation runs outside the transaction.
