Sample request

This sample demonstrates how to issue refunds using the POST /v3/returns/{returnOrderId}/refund endpoint. Replace {returnOrderId} with the actual return order identifier for which you want to process a refund.

curl -X POST "https://marketplace.walmartapis.com/v3/returns/{returnOrderId}/refund" \ -H "Authorization: Basic <Base64EncodedConsumerKey:ConsumerSecret>" \ -H "WM_SVC.NAME: Walmart Marketplace" \ -H "WM_QOS.CORRELATION_ID: 1234567890" \ -H "Accept: application/json" \ -H "Content-Type: application/json"

import requests returnOrderId = "<ReturnOrderId>" # Replace with your actual return order ID
url = f"https://marketplace.walmartapis.com/v3/returns/{returnOrderId}/refund" headers = { "Authorization": "Basic <Base64EncodedConsumerKey:ConsumerSecret>", "WM_SVC.NAME": "Walmart Marketplace", "WM_QOS.CORRELATION_ID": "1234567890", "Accept": "application/json", "Content-Type": "application/json"
} response = requests.post(url, headers=headers)
print("Status code:", response.status_code)
print("Response JSON:", response.json()) 

Modify your code

1. Replace <Base64EncodedConsumerKey:ConsumerSecret> with your actual Base64-encoded credentials.
2. Replace {returnOrderId} with the actual return order identifier for which you wish to process a refund.
