APIs

 The Service Standards File Download API provides an efficient way for mailers to download Service Standards files so they can be consumed programmatically and not require manual intervention.

Receive a comprehensive list of pricing, service standards, and shipping options for USPS products within a single API call.

This API allows customers to create and mange their subscriptions for any adjustments on their packages.  This also includes the listener URL specifications for the webhook to receive adjustment event notifications per package.

Adjustments are any changes or discrepancies detected in the mailstream against a package's manifested characteristics that affect the package's pricing.  For example, if a package was manifested with one weight and mailed with another, an adjustment may be issued for the difference in pricing.

Create a subscription to receive tracking events by mailer ID or tracking number. Manage all tracking subscriptions, in one place, by providing your server URL to receive Postal Service tracking events.  This also includes the listener URL specifications for the webhook to receive tracking notifications per package.

This API returns tracking status and related details for a given USPS package, including scan events and their date, time, and location. The Tracking APIs allow you to integrate the status of your shipment into your customer-facing experience and internal fulfillment processes that will benefit your company by:

• Providing your customers with the latest status and delivery expectations while keeping them within your company’s or organization’s website.

• Integrating status and delivery information for incoming packages or customer returns directly into your systems and processes so that you know when a package will arrive at your facilities.
