PromoStandards is a set of data standards developed by distributors, suppliers, and service providers in the promotional products industry to improve supply chain efficiency. It defines SOAP/XML web services for product data, pricing, inventory, purchase orders, order status, shipment notifications, and invoices. PSRESTful exposes all of these as clean REST/JSON endpoints.

For read-only services like product data, media content, and public inventory, no credentials are needed — just your PSRESTful API key. For transactional services like Purchase Orders, Order Status, and Invoices, you'll need to configure your own supplier credentials in the PSRESTful dashboard.

PSRESTful integrates with PromoStandards-compliant suppliers including SanMar, PCNA, S&S Activewear, HIT, Koozie Group, and hundreds more. Visit our Integrated Suppliers page to see the full list with configuration status.

The Free plan gives you 10 API calls per day across all core PromoStandards services — product data, PPC, media, inventory, purchase orders, order status, shipment notifications, and invoices. No credit card required. It's designed to let developers explore and test integrations before committing to a paid plan.
