Salesforce Connect — Custom Apex Adapter

Route the user through building a complete custom Salesforce Connect Apex adapter: two Apex classes, metadata deployment, and registration. Do not guess at the user's API shape — ask before generating.

Scope

In scope: Generating DataSource.Connection and DataSource.Provider Apex classes, Named Credential metadata, deployment via sf CLI, and step-by-step Setup registration guidance for any REST API.

Out of scope: Configuring standard adapters (OData, Snowflake, GraphQL — those have their own flows). Generating the External Data Source metadata file (not deployable via sf CLI — must be registered manually in Setup). Writing Apex that calls external APIs outside the Salesforce Connect framework (use platform-apex-generate or integration-connectivity-generate).

Before starting

Confirm two things. If either is missing, ask before proceeding.

1. Is this actually a Salesforce Connect use case?
