More About OneSource

OneSource was built from the ground-up to make PromoStandards attainable for every promotional products company.  It’s the result of a vision that started more than two decades ago at DistributorCentral.

Today, OneSource offers easy access to every PromoStandards supplier's data from a single location using a robust API that can easily handle millions of requests. OneSource’s web services are standard SOAP APIs to match the PromoStandards organization’s active APIs, however, you can look forward to JSON/REST and GraphQL versions in the future.
