I need a small yet reliable piece of code added to my site, https://globalshippingltl.com, that triggers Walmart’s “shipment delivered” endpoint whenever we confirm a delivery on our side. I already have an active Walmart API key and the official API reference, so you can jump straight into the integration rather than spending time on credential setup. The site is hosted on Wordpress, you’re free to choose the most efficient language or framework that works with the existing stack; we can review that together once you look at the repository. What matters is that the call authenticates with the API key, sends the proper order IDs and tracking data, and returns a success response that we can log for auditing. Deliverables • A well-documented code snippet or module integrated into the live site that posts the “delivered” status to Walmart. • A simple test harness or demo page I can run to verify the call and view the JSON response. • Brief hand-off notes covering where the code lives, any environment variables, and how to extend the logic for future endpoints. Once you’ve wired it up and we run a successful test in my Seller Center, the job is done.
