Step-by-Step: How to Integrate Walmart and Linnworks in 2025

Step 1: Gather Your API Credentials

You’ll need secure API keys from both Walmart and Linnworks. These include:

  • Walmart Marketplace API Details: Client ID, Client Secret, Consumer ID, Private Key
  • Linnworks Developer Credentials: Application ID, Secret Key, Access Token

Make sure these are generated from the latest 2025 developer dashboards for security compliance.

Step 2: Use a Middleware or Custom Script

You can either:

  • Build a custom API bridge using platforms like Postman or Swagger
  • Use a third-party middleware app built specifically for Walmart-Linnworks integration
  • Hire integration experts (like our team at e-commerzz.com) to develop a tailored sync solution

This bridge is responsible for pulling orders from Walmart into Linnworks, syncing inventory, and updating fulfillment statuses automatically.

Step 3: Test Everything Rigorously

Before going live:

  • Simulate order placements
  • Validate that inventory adjusts across both platforms
  • Check if order statuses are updating in real-time
  • Review error logs to catch any sync failures

Never skip this step—testing ensures a seamless launch.

Step 4: Launch & Monitor

Once testing is complete, activate your integration. Monitor the sync daily for the first few weeks. Use performance reports from Linnworks to track issues and make improvements as needed.
