Integrate with Stamps.com
The Stamps.com Developer Program provides you with the technical resources and support you need to develop your own application based on Stamps.com technology or integrate USPS shipping into your existing software and workflow. Register now for 24/7 access to complete documentation, code samples and FAQs.
Stamps.com offers four distinct technology platforms to choose from, depending on your technical requirements, business needs and development preferences:
Web Services API
Deliver shipping labels anywhere you want them, exactly when you need them. Stamps.com's SOAP-based Web Services platform allows you to generate USPS shipping labels in virtually any technology environment necessary. The API also supports address cleansing, rating, package tracking, and more. Ideal for web-based ecommerce integration or any web-hosted application. More info on Stamps.com Web Services API.
Software Development Kit (SDK)
Insert Stamps.com postage printing into your application and your workflow without the need to develop your own user interface. This traditional client-based SDK allows you to integrate the Stamps.com software and pre-built User Interfaces directly into your own software application. Use only the software modules that you need. More info on Stamps.com Software Developer Kit.
Exchange information between Stamps.com and any other software program using the Stamps.com XML format. This standardized format allows you to print postage and verify addresses, either singly or in batches. Details such as tracking and cost are returned by Stamps.com using the same XML format. More info on importing data via XML into Stamps.com.
Automate your shipping by retrieving order information directly from the data source - and posting it back. When you configure an ODBC connection, Stamps.com can communicate directly with your data source, including any Excel, CSV, Access, My SQL, SQL Server, Oracle and other database formats. More info on Stamps.com ODBC connections.
