Using C#/.NET to Integrate with USPS?
You can't do it through USPS. They use SOAP/XML for their endpoints with absolutely no client libraries or documentation to support you, but you can use Easypost to connect to USPS today using C#/.NET.
With EasyPost's USPS C#/.NET API, you can:
- Print labels at the industry's lowest price
- Track every outbound (or inbound) package
- Verify every address, domestic or international
- Shop for rates across your shipping accounts
- Automate package insurance with low premiums
