ABC Telecom uses Communications Cloud while its distributors use their own CRM system.

TM Forum 620 Product Catalog Management APIs provide a standardized telecommunications interface for exchanging product offerings, specifications, categories, and related catalog information with external partner systems. Using the productized TMF620 API lets distributors consume a vendor-neutral representation instead of depending on Salesforce ' s internal Product2 or EPC object structure. The key is to represent the requirement in the same layer where Salesforce evaluates that business state. CPQ cart APIs are transactional and do not provide the catalog-exchange abstraction, while generic Object REST exposes Salesforce-specific storage rather than the industry-standard product-offering model. TMF620 is the better interoperability boundary for distributor catalog setup. This avoids mixing customer-facing product logic with downstream technical state or using integration code as a substitute for catalog and orchestration design. When the model is aligned correctly, the platform can validate the request, retain the required lifecycle information, and generate the appropriate downstream action without redundant processing. That improves auditability and makes later changes easier because administrators can adjust the relevant metadata rather than reworking multiple custom components.
