Salesforce Connect adapter types
Key Takeaway
Choose the adapter in the Type field of the external data source, based on where the data lives and how that system exposes it.
Salesforce Connect lets your org work with data that lives somewhere else, such as another Salesforce org or an outside system. It reaches that data in real time through web service callouts. It talks to each system through a protocol-specific adapter.
What an adapter is
An adapter is the connector Salesforce Connect uses to reach one kind of external system. You choose the adapter in the Type field when you define an external data source. The protocol the other system speaks decides which adapter you choose.
Think of an adapter as a plug shaped for one type of outlet. The outlet stands for one kind of external system, and the plug stands for the adapter that fits it.
