Test mode is a checkbox on every carrier connection except Royal Mail, Posti and DSV XPress. When it is on, Zippendo sends your shipments to the carrier’s test system instead of the real one. Use it to try a carrier before you go live. Leave it off for real shipments. It is off unless you tick it. Walkthrough: Carriers. Every carrier field: Carrier credentials.
Leave Test mode off for real orders. Shipments sent in test mode are only tests, so never put a test label on a parcel you ship. If Test mode does not match your credentials (test credentials with it off, or real credentials with it on), sending fails, usually with The carrier rejected your login details. Update the carrier credentials under Carriers.

​
Where to find it

  • New carrier: in the sidebar, click Carriers → All carriers → Connect on the carrier. Test mode is under Optional fields in the Connect carrier window.
  • Connected carrier: click Carriers → My carriers → Edit carrier. Test mode is in the Carrier settings section.
The setting belongs to the carrier connection. You cannot turn it on for a single shipment, shipping rule or printer.

​
Which credentials to use

Some carriers give you separate test credentials. Others use the same ones for testing and for real shipments. Test mode does not change anything else in Zippendo. The shipment still gets a label and tracking number, and it counts toward the shipments on your plan like any other. The carrier never moves a test shipment, so expect few or no tracking events on it.

​
Test with Posti

Posti says it invoices a shipment only when the parcel is actually shipped, so a test label you never hand over costs nothing. Posti notifies the receiver, so put your own email address and phone number on a test shipment. Zippendo cannot cancel a Posti shipment. See Connect Posti.

​
Test a carrier, then go live

1

Connect the carrier with Test mode on

Fill in the credentials the carrier gave you for testing (see the table above) and tick Test mode.
2

Send a test shipment

Create a shipment with this carrier and send it. Check that the label and tracking number come back.
3

Switch to live

Open the carrier with Edit carrier. Untick Test mode, replace any test credentials with your real ones, and click Save.
To keep testing after you go live, connect the carrier a second time with its own name, for example “GLS Denmark (test)”, and Test mode on. The second connection counts toward the number of carriers your plan allows.
