Web Services Overview

[This is preliminary documentation and is subject to change.]

Purolator International provides a SOAP web service interface for customers who wish to write their own software to interact with Purolator’s Online Shipping System. Web services is fully integrated with the OLS web site so any orders/shipments/closeouts will also be available there.

  • The FAQ page contains short answers to the questions we are asked most frequently.

  • The How To pages contain more detailed information on how to create and closeout both courier and LTL orders, and on how to send label data to a ZPL printer.

  • The Example Requests and Responses pages contain sample SOAP requests and responses to help clarify what the requests and responses should look like.

  • The Return Codes page contains a table of return codes and the associated error message(s) and indicates which requests might generate each error.

  • The API Reference section contains complete MSDN style documentation for the web service code.
