What can a developer use to create a Custom Adapter for Salesforce Connect?

A developer can utilize the Apex Connector Framework to create a Custom Adapter for Salesforce Connect. This framework provides the necessary tools and infrastructure to integrate external data sources with Salesforce, allowing developers to define how Salesforce interacts with that data.

The Apex Connector Framework is specifically designed for building the integration layer, enabling the creation of custom adapters that can handle complex data processing and communication between Salesforce and external systems. It allows developers to define the data structure, query logic, and handling mechanisms for the data being connected.

Other options such as JavaScript API, REST API, and SOAP API serve different purposes within the Salesforce ecosystem. While the REST and SOAP APIs facilitate standard communication protocols to interact with Salesforce data and services, they are not designed for building custom adapters. The JavaScript API is primarily focused on integrating web applications with Salesforce and does not pertain to the creation of Salesforce Connect adapters.
