Swiss Post integration for labels and parcel references

The Swiss Post integration creates a label from a shipment prepared in myFulfillment, without re-keying the address in a carrier portal. The module keeps the consignment identifier returned with the document. Orders, warehouse checks and cross-dock flows remain in myFulfillment before the parcel is handed to Swiss Post.

Overview

How Swiss Post fits with myFulfillment

What is Swiss Post?

Swiss Post is Switzerland's national postal operator. For an e-commerce merchant, its role begins with carrying the parcel. myFulfillment manages the layer before that: orders from connected channels, allocation, preparation, checks and carrier-service selection. The Boostmyshop integration uses Digital Commerce API client authentication and the Barcode service to request a label with the address, weight, service and print settings. It then stores the returned document and consignment identifier. Tracking events, PickPost and shipping options are separate Swiss Post APIs, activated on their own.

Our verdict

When Swiss Post is enough, and when myFulfillment makes the difference

Our operational assessment: the connection is solid for creating a Barcode label and keeping its identifier in a multi-channel flow; Swiss Post's other APIs are activated on their own.

Strengths · Limits
Strengths
  • A direct Digital Commerce API connection with client authentication
  • Packing-station output in PDF, sPDF or ZPL2, from A5 to A7
  • Specific Swiss services and options, including PostPac, Saturday, signature, VinoLog and SameDay
Limits
  • Comparison uses prices configured in myFulfillment, not a live Swiss Post rate request
  • The consignment identifier is stored on the shipment; tracking events go through the Track Consignments API
  • PickPost and Swiss Post's other APIs are activated separately from the integration

In practice

How our customers use Swiss Post day to day

In daily operations, Swiss Post becomes one step in the preparation flow instead of a second data-entry station. The operator works in myFulfillment, checks the parcel, selects an allowed service and receives the carrier document with its shipment reference.

01
Create the label at the packing step

After the parcel check, myFulfillment sends Swiss Post the address already held on the order, the weight, the service and the print settings. The document is attached to the shipment.

02
Select from configured services

The team can use PostPac Economy, PostPac Priority and other services enabled for the account. The compared price comes from carrier-account configuration, not a live rate request to Swiss Post.

03
Keep the reference without copying it

Swiss Post returns the consignment identifier with the label. myFulfillment attaches it to the shipment, where the team finds it without re-keying it from a carrier portal.

04
Ship a cross-docked order

A product received for a waiting order is checked, prepared without long-term storage and labeled with Swiss Post on departure. Cross-docking remains a myFulfillment capability, not a carrier API feature.

A comparable operation

Multi-channel orders to prepare, followed by parcel data re-entry for every carrier label.

Preparation stays in myFulfillment and the Swiss Post label is requested at the packing station.

Getting started

Connect Swiss Post to myFulfillment, step by step

  1. 1Open a Swiss Post business billing relationship and request Digital Commerce API access through the developer portal.
  2. 2In myFulfillment, enter the client ID, secret and franking license number without copying them into shared operating notes.
  3. 3Enable only the services and options covered by your Swiss Post relationship, then choose the paper size, file type and resolution.
  4. 4Test an order with its address, weight and service, then check the label and consignment identifier before opening the regular flow.
Before you connect

A Swiss Post business billing relationship and API credentials are required. The integration creates the Barcode label and keeps the identifier returned with that document. Compared prices come from carrier-account configuration. Tracking-event retrieval and PickPost point search belong to separate Swiss Post APIs, subscribed on their own. Service and option availability depends on the merchant's Swiss Post relationship.

FAQ

Swiss Post: frequently asked questions

You need a Swiss Post business billing relationship and Digital Commerce API access. In myFulfillment, the Boostmyshop module asks for a client ID, secret and franking license number. Test one label with a real address, weight and service combination before opening the regular flow.

The integration offers PostPac Economy, PostPac Priority, Saturday variants, bulky-goods services, Swiss-Express Moon, VinoLog and SameDay. A service in the integration does not replace account eligibility. Enable only the services included in your Swiss Post relationship.

The integration offers A5, A6 and A7 paper sizes, PDF, sPDF or ZPL2 files, and 200, 300 or 600 dpi resolution. The chosen setting is sent when the Swiss Post label is created.

No. The comparison goes through the Swiss Post services and reads the price configured in the myFulfillment carrier account. No rating request is sent to Swiss Post at calculation time.

The integration picks up the consignment identifier returned with the label and stores it on the shipment in myFulfillment. Detailed journey events belong to Swiss Post's Track Consignments API, subscribed on its own.

Swiss Post publishes PickPost as a separate API, which the current integration does not call. If pickup-point choice is essential at checkout, plan that flow from the start of the project.

For this service only, the integration combines the RETR code with the PRI service during label creation. Other Swiss Post services do not have this return flow preconfigured; each case depends on the service and your contract.

No. The sales channel's Boostmyshop module imports the order into myFulfillment. The team then prepares the parcel and selects Swiss Post as the carrier. This separation lets the same carrier connection serve eligible orders from several channels.
