Look up which PromoStandards suppliers support a given service and WSDL version via the official WebServiceRepository directory API

Steps
Call the REST/JSON directory at services.promostandards.org/WebServiceRepository/WebServiceRepository.svc/json/companies to list all registered company codes
Call the companies/{companyCode} endpoint to get a specific supplier's registration info
Call the services/types endpoint to get the list of valid service type codes (e.g., INV for Inventory, OS for Order Status)
Call companies/{companyCode}/endpoints/types/{serviceTypeCode}?version={version} to get that supplier's actual WSDL endpoint URL for a given service and version
Alternatively consume the full directory as one call via the SOAP 1.2 WSDL at WebServiceRepository.svc?singleWsdl
Known gotchas
This directory is read-only metadata about who implements what — it does not proxy or execute the underlying service calls themselves
The directory can lag behind a supplier's actual production status; confirm an endpoint is live before building against it rather than trusting the listing blindly
Company codes are PromoStandards-assigned identifiers (e.g., STAR), not the supplier's common brand name, so a lookup step is needed to map codes to recognizable suppliers
