Get started

The Return Label API is very closely related to the carrier and method selection and shipment label APIs, so you will find that many of the structures and components overlap with those. Required and optional fields are defined in the table for the previous example.

Generate a return label

The Shipium Return Label API assumes you're using one of the authentication mechanisms detailed in our authentication documentation.

📘
Authentication for API Calls
In the cURL example on this page, the environment variable AUTHSTRING is used to handle authorization. The recipe below shows how to set it correctly for both API Key and OAuth users.

The following table provides required and optional fields for calling the Return Label API. You can find additional support in the Return Label API Reference.

Request field	Required/Optional	Field properties	Description
`currencyCode`	Required	String Example: USD	Currency in which all the rates for shipping carrier selection costs will be calculated
`generateLabel`	Optional	Boolean `True` or `False`	When `true`, a request to the selected carrier will be sent to generate a label for the shipment based on the information provided in the `labelParameters` field of this object. When `false`, this step is skipped and the system will record what carrier service method would have generated a label for.
`labelParameters.testMode`	Optional	Boolean `True` or `False`	When `true`, calls to generate the labels will be made to the carrier sandbox servers. No actual labels are created, only a representation of the label. No money is charged to the underlying account.
`labelParameters.currencyCode`	Optional	String	Currency in which all the rates for shipping carrier selection costs will be calculated
`labelParameters.labelFormats`	Required	String Supported formats are: - PDF - PNG - ZPL	List of formats to generate the package label in
`labelParameters.manifest`	Required	Boolean `True` or `False`	When `true`, a manifest for the label is generated. While manifesting is optional, this field value must be provided.
`labelParameters .includeLabelImagesInResponse`	Optional	Boolean `True` or `False`	When `true`, the response will include the raw image data of the labels that were requested to be generated by the carrier.
`labelParameters .contentDescription`	Optional, but required for return shipments	String	A short description (under 35 characters) of the package contents being returned that is passed on to the carrier; required for return shipments only
`labelParameters .customLabelEntries`	Optional	String	List of formats in which to generate the package label
`destinationAddress.addressType`	Optional	String enumeration Values are: - Commercial - Residential	The type of location for the destination address

`destinationAddress.city`	Optional	String	The name of the city for the destination address
`destinationAddress.state`	Optional	String	The 2-letter postal abbreviation of the state for the destination address
`destinationAddress.postalCode`	Required	String	A country-code-appropriate postal code for the destination address
`destinationAddress.countryCode`	Required	String	The ISO 3166-1 country code for the destination address
`originAddress.addressType`	Optional	String enumeration Values are: - Commercial - Residential	The type of location for the origin address
`originAddress.name`	Optional	String	The name of the contact for the origin address
`originAddress.company`	Optional	String	The company name for the origin address

`originAddress.postalCode`	Required	String	A country-code-appropriate postal code for the origin address
`originAddress.countryCode`	Required	String	The ISO 3166-1 country code for the origin address
`packagingType.packagingMaterial`	Optional	String enumeration Values are: - Box - Envelope - Flat_Pack	The type of packaging used to create the package for the shipment
`packagingType.packagingSizeName`	Optional	String Example: 13x12x10 Box	A custom name for the packaging

When this value is absent, `linearDimensions` is required.
`packagingType.linearDimensions .linearUnit`	Optional, but required if the `packagingTypeId` is not included	String enumeration Values are: - cm (centimeter) - in (inch)	The unit in which linear dimensions are provided
`packagingType.linearDimensions .length`	Optional, but required if the `packagingTypeId` is not included	Number ($float) Example: 13	The longest linear dimension (i.e., the longest side of a box or envelope)

`customerReturnParams .returnRequestDateTime`	Optional	String ($date-time)	ISO-8601 formatted date of the return request, if not set, the current date-time will be used.
`customerReturnParams .contentDescription`	Required	String	A short description (under 35 characters) of the package contents being returned that is passed on to the carrier

Example cURL request

The request looks very similar to a shipment label request. You pass information about the origin address and destination address, as shown in the cURL request below:

curl --request POST \
     --url <<api_url>>/api/v1/deliveryexperience/customerreturn/label
     --header 'accept: application/json' \
     --header $AUTHSTRING \
     --header 'content-type: application/json' \
     --data 'INSERT REQUEST BODY FROM BELOW'

Example request body

The following example includes partnerReturnRequestId, customLabelEntries, and orderItemQuantities. All these are optional and can be omitted. You can find more details about custom label entries in Label Customization. The table describing request fields in the section above and the Return Label API Reference provide details about information to include in the API request.

Example response body

The return label response is almost identical to the response returned by the shipment label, though with some differences as carrier costing does not occur for return labels.

Retrieve previously created labels

You can retrieve previously created labels by calling the same API endpoint you used to generate the label, using the GET request type and passing the returnLabelId you previously received in your response body.

Here's the cURL example call for retrieving a return label. You'll replace the returnLabelId value with the one you received during label generation.

curl --request GET \
     --url  <<api_url>/api/v1/deliveryexperience/customerreturn/label/{returnLabelId}
     --header 'accept: application/json' \
     --header $AUTHSTRING \
     --header 'content-type: application/json'
