Custom API Development Skill

This skill guides you through developing Custom APIs for Salesforce B2C Commerce. Custom APIs let you expose custom script code as REST endpoints under the SCAPI framework.

Tip: If b2c CLI is not installed globally, use npx @salesforce/b2c-cli instead (e.g., npx @salesforce/b2c-cli code deploy).

Scope & grounding

This skill provides CLI-specific workflows and quickstart patterns for Custom API development. It covers OpenAPI 3.0 contract structure, OAuth scope configuration, cartridge-path resolution rules, and circuit breaker behavior. However, platform-specific validation rules, operational limits, security scheme requirements, and Script API integration patterns can drift across Commerce Cloud releases. Before answering questions that reference specific API versions or framework behavior, or before emitting code the user will run, confirm current platform specifics against the official documentation via b2c docs search / b2c docs read (CLI) or docs_search / docs_read (MCP). The official documentation is the authoritative source for Custom API contract specifications, runtime behavior, and B2C Commerce platform details not covered here.
