Integration With Shippo

Last Updated: March 22, 2026

ReturnGO integrates with Shippo to help you manage your returns shipping.

Shippo is a shipping aggregator that connects you to a wide range of carriers for automating return shipping labels to save you time and money.

For the best experience, it’s recommended to use Ship by ReturnGO, ReturnGO’s built-in shipping solution. Ship by ReturnGO is available on all plans and needs no integration.

Capabilities

The ReturnGO-Shippo integration supports:

Pay-on-scan return labels
QR code generation through supported carriers:
- Evri - for both forward and return labels.
- USPS - only for forward labels, and only for supported services. Unsupported modes will result in an error.
Live tracking status updates
Auto-select-cheapest

Requirements

To link your Shippo account to ReturnGO, you will need:

A Premium plan or higher
Shippo Account
- Make sure you have a Shippo web app account.
Shippo API token
- Log in to Shippo > Settings > API to generate a live API token.
Shippo API (Latest Version)
- Log in to Shippo > Settings > API to verify or upgrade your Shippo API version.
- In some cases, using an older Shippo API version can prevent label creation.

Valid Payment Method
- A valid payment method must be registered in your Shippo account.
- Log in to Shippo > Settings > Account > Billing to set up a payment method in Shippo.

When choosing a carrier, it should be configured to support return labels.

Otherwise, the carrier may show up in your shipping account but will not be listed as a carrier option in ReturnGO.

Linking your Shippo Account to ReturnGO

To link your Shippo account to ReturnGO:

Go to Integrations.
Click on ADD PRODUCT OR SERVICE.
Choose Shippo from the drop-down list.
Click on the green check mark.

5. Enter your credentials.

6. Click CONNECT.

Adding the Integration to a Return Method

Once you've connected the integration, you'll need to add it to a return method:

Go to Settings > Return Methods.
Open the Ship with pre-paid label section.
Click ADD RETURN METHOD or select a return method to edit.

4. Open the Shipping Label Settings section.

5. Set Connection to Shippo.

6. Select a carrier/service level.

7. Set the Dangerous Goods Type, such as:

Not Dangerous
Other
Lithium Batteries
Biological Materials

Note: Please select the correct option. Dangerous goods information is required for some carriers, such as USPS. ReturnGO does not validate whether the selected dangerous goods type meets the carrier’s requirements, which may vary by domestic or international shipment and hazardous material type.

8. Verify your return address and shipping instructions.

9. Click on the save icon to save your changes.

Note: You can choose to disable the shipping address validation that Shippo performs when a shipment is created, by enabling the toggle under Return Methods > Shipping Label Settings.

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 require that the return address be registered or linked to your carrier account.
If the address is not associated with your shipping account, the label may fail to generate and display an error such as No shipping locations found.
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 order's shipping 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.
