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 carriers support forward deliveries only, returns only, 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 takes 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 if you can Generate a Return Label for the Order Directly in the Shipping Platform. 

  • If your shipping service platform cannot generate the label, then it will also fail in ReturnGO.
