Building on the SanMar API? Here's the developer walkthrough. SanMar is a top supplier of wholesale apparel and accessories, with both EDI and API services. The aim: a secure, scalable integration with your eCommerce, ERP or inventory system. First, get SanMar's documentation and credentials: an API key, or FTP or VAN setup for EDI. Then know your REST or EDI standards, your data formats, and tools like Postman. Step one, authentication. The guide's API example passes your key in the authorisation header. For EDI, secure FTP moves the 850 purchase order and the 856 ship notice. Step two, mapping. Map SKU, quantity and order number to SanMar's requirements, and watch product codes, units of measure and address formatting. Step three, workflows. Inbound, you place orders. Outbound, you pull inventory, acknowledgments, ship notices and invoices. The guide's code samples are illustrative, so confirm every endpoint in SanMar's own documentation. Step four, errors and pagination. Capture status codes, retry server errors and rate limits, and page through large data sets. Then test every workflow, deploy securely with encrypted credentials and alerting, and keep monitoring SanMar's updates. A custom SanMar integration is more than the first build. Authentication changes, API versions move, and error handling never stops. APIWORX builds, monitors and maintains SanMar integrations for you, with our ops team on every flow.
