Implement B2B punchout catalog integration with headless buyer experience

Real World Scenario

Enterprise buyer procurement system punchout lands in Salesforce Commerce B2B storefront but return cart cXML fails validation breaking ERP requisition creation.

Expected Answer

• Implement cXML punchout setup and return cart handlers per buyer procurement system requirements • Maintain buyer-specific catalog visibility and contract pricing in punchout session context • Validate return cart payload schema before redirect preventing ERP rejection loops • Map Commerce cart lines to buyer ERP material numbers via integration middleware • Session timeout handling with cart persistence and punchout session token renewal • Support level 2 punchout where checkout completes in buyer system not Commerce • Monitor punchout success rate, return cart errors, and buyer-specific integration logs

Main difference: use case and scale. Implement cXML punchout setup and return cart handlers per buyer procurement system requirements. Maintain buyer-specific catalog visibility and contract pricing in punchout session context. Pick based on your integration pattern and team capability. Punchout is integration-heavy B2B—cXML correctness and buyer-specific mappings matter more than storefront UX polish. Document the decision in an ADR and align with enterprise standards.
