Integration With Envoi du Net

Last Updated: May 28, 2024

ReturnGO integrates with Envoi du Net to help you manage your return shipping. Envoi du Net is a French 3PL (Third-Party Logistics) provider through which you can generate return shipping labels and manage your return shipments.


When a return request is approved, ReturnGO alerts Envoi du Net to create a return, and gets the return label accordingly.

The Envoi du Net integration supports:

  • Generating domestic return labels
  • Live tracking status updates

Troubleshooting the Integration 

Many of the issues encountered related to integration can be identified during setup or label generation. 

Here are a few things you can check to try and fix such issues: 

Setup Issues 

Make sure your API credentials are accurate. 

  • There should be no extra spaces before or after each API entry. 
  • Make sure you are using live or production API credentials, and not dev or test APIs. 
  • Try to re-generate a new API key and reconnect. 
  • If a carrier or service level is not available, contact your shipping service support team to verify which return services are available. 

Note: Some shipping carriers support only forward deliveries, only returns, or both.

Label Creation Issues 

Verify your Return Address

  • Some carriers may not recognize special characters, which might cause issues when generating labels.
  • Remove special characters and unnecessary spaces in your return address.
    • For example: 
      • If your store name is “John & Jane Store”, change it to “John and Jane Store”. 
      • If your store phone number has “+” signs or “( )”, remove them. 

Verify the Customer’s Address

  • ReturnGO collects the customer’s address when the request is submitted.
  • If there are corrections to the customer’s address, reject and resubmit the return request. 

Verify the Item Weight

  • If the total weight of the items being returned exceeds the service level’s weight limit, then the carrier will reject the label request.

Verify That the Shipping Platform Can Generate Return Labels

  • If your shipping service platform cannot generate the label, label generation will be unsuccessful in ReturnGO as well.
