Digital Commerce is the Communications Cloud channel layer designed for high-volume product discovery, configuration, basket management, and self-service ordering. It lets an external portal consume offers and commerce functions from the same Enterprise Product Catalog and CPQ environment without replicating the full catalog into another selling platform. This keeps Communications Cloud as the commercial system of record while exposing channel-appropriate APIs to the web experience. This approach is preferable because it uses the platform feature designed for the exact lifecycle stage involved, rather than forcing the requirement into a neighboring layer. EPC APIs are primarily catalog-management interfaces, while cart APIs operate at a lower transactional CPQ level. Digital Commerce provides the optimized digital-browsing and basket abstraction required for consumer portal use cases and peak digital traffic. In Communications Cloud, that separation materially affects maintainability, performance, and the accuracy of future MACD or order-processing behavior. The solution should therefore preserve parent-child and inventory dependencies, use standard qualification or orchestration semantics, and ensure that downstream systems receive only the information relevant to their responsibility. The same design also simplifies regression testing because the business rule is expressed in one authoritative place and can be validated independently from unrelated product or integration behavior.

A custom Apex integration adapter is justified when the downstream system requires a payload format and error semantics that the standard adapters and declarative mappings cannot represent cleanly. Apex can control serialization, HTTP behavior, response parsing, exception translation, and the mapping of non-standard errors into Order Management processing while still being invoked through the normal System Interface and orchestration model. This approach is preferable because it uses the platform feature designed for the exact lifecycle stage involved, rather than forcing the requirement into a neighboring layer. DataRaptor/Data Mapper can transform data but does not by itself implement the complete transport and custom response semantics. Manual handling should not replace an integration that can be automated reliably.

UX design, reservation API design, and inventory-system integration should be planned as coordinated parallel workstreams once the interface contract is understood. The UX team needs the shape and behavior of the reservation API, but it does not need the complete downstream implementation to be finished before prototyping and validation can begin. Frequent integration checkpoints keep the streams aligned and shorten elapsed delivery time. The recommended configuration follows the native Communications Cloud responsibility boundary: catalog and CPQ determine the commercial request, while Order Management, OmniStudio, or the relevant platform service performs the downstream processing required by the use case. Fully sequential delivery creates avoidable waiting and often exposes integration constraints too late, forcing redesign. The goal is contract-first collaboration rather than one team completing all work before the next begins. Avoiding duplicate logic is important because repeated rules across catalog, integration, and orchestration layers quickly become inconsistent as products evolve. The selected approach keeps the authoritative data in the correct object model, supports later lifecycle operations, and minimizes additional processing or manual intervention. It should be implemented declaratively wherever the platform feature can express the requirement, with customization reserved only for behavior that genuinely falls outside the supported framework.

Suspend and Resume represent temporary operational state changes that preserve the underlying service relationship, so they typically require explicit lifecycle handling beyond the basic Add/Modify/Disconnect patterns. The solution must define how those actions map to downstream provisioning, billing, assurance, orchestration conditions, and asset/technical-inventory state so that the service can later resume without being recreated as a new commercial product. This is the decisive architectural point in this scenario because the Salesforce Industries model separates commercial selling concerns from fulfillment, lifecycle, and integration concerns. Treating suspension as a normal Disconnect loses the temporary-state semantics. The business process should therefore be modeled deliberately across CPQ, Order Management, and downstream integrations. Using the standard capability also keeps the design supportable across releases, reduces unnecessary custom code, and makes operational behavior easier to trace during troubleshooting. From an implementation perspective, the configuration should be tested with representative product structures and transaction volumes so that rules, mappings, and downstream dependencies behave exactly as intended. The resulting design is therefore both functionally correct and aligned with the managed Communications Cloud operating model.
