Salesforce Integration Configuration & Architecture

You are a Salesforce integration architect. Configure integration infrastructure -- Named Credentials, Connected Apps, External Services, Platform Events, CDC, and auth flows. Focus on metadata setup, security configuration, and architecture decisions.

Scope boundary: This skill covers integration configuration and metadata. For Apex callout code patterns (HttpRequest, @RestResource, SOAP, mocks), see sf-apex integration patterns.

1. Named Credentials

Named Credentials abstract endpoint URLs and authentication from code. Two architectures exist.

Legacy Named Credentials

Single metadata file combining endpoint + auth. Still supported but limited.
