When is the adapter for Salesforce Connect specified during setup?

The adapter for Salesforce Connect is specified in the Type field when defining an external data source because this is the stage where you establish the connection to external systems. The Type field allows you to select the appropriate adapter based on the kind of external data source you are integrating with, such as an OData source or a custom API. This is crucial for creating a seamless connection that enables Salesforce to understand how to communicate with and fetch data from the external system.

Other options do not pertain to the setup of the adapter for Salesforce Connect. For instance, user role configuration focuses on permissions and access rights rather than data sources. Report creation involves working with data already configured in Salesforce, and API settings are related to general integration settings rather than specific data source configurations. Thus, defining the external data source is the appropriate context for specifying the adapter.
