Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Authentication for Salesforce Connect Custom Adapters

Your DataSource.Provider class declares what types of credentials can be used to authenticate to the external system.

If your extension of the DataSource.Provider class returns DataSource.AuthenticationCapability values that indicate support for authentication, the DataSource.Connection class is instantiated with a DataSource.ConnectionParams instance in the constructor.

The authentication credentials in the DataSource.ConnectionParams instance depend on the Identity Type field of the external data source definition in Salesforce.
  • If Identity Type is set to Named Principal, the credentials come from the external data source definition.
  • If Identity Type is set to Per User:
    • For queries and searches, the credentials are specific to the current user who invokes the query or search. The credentials come from the user’s authentication settings for the external system.
    • For administrative connections, such as syncing the external system’s schema, the credentials come from the external data source definition.
