Which connector should be used to execute a Dataverse custom action?

The appropriate connector for executing a Dataverse custom action is the Dataverse connector. This choice is correct because the Dataverse connector is specifically designed to allow interactions with Dataverse entities, including executing custom actions that have been defined within Dataverse.

Using the Dataverse connector enables you to perform a variety of operations on your data, such as creating, updating, deleting records, or invoking custom actions. Custom actions in Dataverse are typically used when you need to perform operations that are not directly tied to the default create, read, update, and delete (CRUD) actions that come with standard entity operations.

When setting up integrations or flows that need to utilize these custom actions, the Dataverse connector ensures that all the required parameters and context are handled correctly, making it easier to incorporate logic that may be encapsulated within the custom action.

The other options provided either do not specifically cater to the execution of custom actions or represent broader categories that do not directly apply. For instance, Dynamics 365 and Power Apps connectors provide access to broader functionalities of the respective platforms but do not directly target the execution of Dataverse-specific custom actions.
