Through the package tracking Early Adopters Program, which is available in all countries, shipping companies can sign-up to participate in this feature and give feedback on how to improve it. To take part in the program, a carrier will need to provide a RESTful JSON or XML API that returns the package tracking information. We can work with you to reuse an existing API or setup a new one.
Interested in providing package tracking information to your customers? Please review the full eligibility requirements and fill out the interest form.
If you have any questions, let us know through the forum or on Twitter.
