Salesforce B2B Commerce Apex Extensions (CartExtension Namespace)
Before Writing Code
ALWAYS fetch live documentation BEFORE writing any Apex code:
- Web-search: "Salesforce B2B Commerce Apex developer guide 2026"
- Web-search: "Salesforce B2B Commerce checkout integration Spring 2026"
- Web-fetch official Salesforce documentation for:
- B2B Commerce ConnectApi namespace reference
- CartExtension namespace and AbstractCartCalculator class
- Apex governor limits (latest release notes)
- Test class requirements and best practices
- Web-fetch:
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/ - Web-fetch:
https://developer.salesforce.com/docs/commerce/salesforce-commerce/guide/b2b-cart-calculate.html
Why this matters: Salesforce releases three times per year (Spring, Summer, Winter). Commerce APIs, CartExtension interfaces, and governor limits change. Live docs prevent using deprecated patterns.
