USPS Integration for Postage and Labels

The USPS integration lets Pipe17 buy postage through the USPS APIs as soon as a packer requests labels at a store or warehouse. Each label and tracking number is bought on your own business account.

The Solution for USPS Integration & Order Management

USPS Carries the Parcel. Pipe17 Picks the Store and Buys the Label.

Shipping from stores on your own USPS account often takes an iPaaS to move parcel details and a legacy OMS to decide which location packs. Pipe17’s Order Operations Platform covers both jobs, with order management that sends each order to the right store and a USPS label per carton bought on your account.

Check the Price Before You Buy

Before buying, the packer compares USPS mail classes by cost for that carton. Pipe17 then buys the chosen class and attaches the tracking number.

Automated USPS Data Flows

Pipe17 sends USPS three kinds of request: prices, labels, and cancellations. Three results follow in Pipe17: mail-class prices for the packer, a label with its tracking number, and a shipment ready to hand over.
  • Check USPS Prices. Pipe17 asks USPS to price the carton in each mail class, from the packing location to the customer’s address.
  • Buy the Label. Pipe17 buys one USPS label per carton on your business account, in the mail class the packer chose or your default class. The ship-from address belongs to the packing location, such as a store on a ship-from-store order or a warehouse working through the Pipe17 API. USPS insurance is added on request.
  • Cancel a Label. A packer can cancel a label in Pipe17, which voids it with USPS, then request a replacement for the carton.
  • Prices by Mail Class. A cost for every USPS mail class on offer for the carton, in front of the packer at the packing station.
  • Label and Tracking Number. A 4×6 label file per carton in PDF, TIFF, or JPG, with its USPS tracking number and mail class, filed by Pipe17 on the shipment’s label record.
  • Shipment Ready to Hand Over. With every carton labeled, Pipe17 marks the shipment ready for fulfillment, recording USPS as the carrier and the mail class. The tracking number then reaches the sales channel at handover.

USPS Integration FAQs

With the USPS integration, Pipe17 buys a USPS label for each carton on your own USPS business account as the carton is packed. The request comes from a packer at the counter using the StoreOps app, or from any system calling the Pipe17 API. USPS returns a label and tracking number for every carton, and Pipe17 keeps both with the shipment for printing and handover.

Pipe17 is an order management system (OMS) with a USPS integration that buys labels on your own USPS business account. Pipe17's order routing sends each order to the store or warehouse that should ship it, and the packer requests labels there. The USPS tracking number goes back to the sales channel at handover, with no separate tool passing shipment data to USPS.

Your own USPS business account's pricing applies to every label Pipe17 buys through the USPS integration, not a rate set by Pipe17. Postage is paid from your Enterprise Payment account, and you connect by authorizing Pipe17 through USPS. Connecting also needs your Customer Registration ID (CRID) and Mailer ID (MID), which USPS issues to business mailers.

Pipe17 can buy USPS labels for Priority Mail, Priority Mail Express, USPS Ground Advantage, Parcel Select, Media Mail, and Library Mail. A label request names the mail class when one shipment needs a different one. Every other request uses the integration's default mail class, which starts as Priority Mail and is yours to change.

Yes, a packer using the StoreOps app can see what each USPS mail class costs for a carton before Pipe17 buys anything, then choose the class that fits the order's delivery speed and budget. Pipe17 buys the chosen label on your USPS business account and attaches its tracking number to the shipment. The label is then ready to print at the packing station.

USPS labels from Pipe17 come as 4x6 files in PDF, TIFF, or JPG, and PDF is the setting until you pick another. Choose the format once on the integration, based on the printers your stores and warehouses run. Every file sits in Pipe17 next to its USPS tracking number, where a packer prints it at the counter or an API caller downloads it.

Yes, a packer can cancel a USPS label in Pipe17, which voids it with USPS, and request a replacement label for the carton. Typical reasons are the wrong mail class or a carton repacked into a bigger box. The replacement is a new label bought on your USPS business account, with its own tracking number.

Yes, Pipe17 lets one organization run USPS beside other label providers. In StoreOps, each store names its provider or keeps the organization default. Packers at one location can buy USPS postage on your business account while packers at another use the EasyPost integration or the Easyship integration, all in the same packing screen.

You need a USPS business account with a Customer Registration ID (CRID), a Mailer ID (MID), and an Enterprise Payment account for postage. Add the USPS integration in Pipe17, click Connect to authorize Pipe17 through USPS, and enter those numbers. Then choose a default mail class and label format, and select USPS as the label provider for the stores that should use it.
