Connecting an Integration

Ready to link your first platform to Merchkit? This guide walks you through the authentication and connection process for any supported platform.

​
Supported Platforms

Merchkit currently integrates with:
  • Shopify — Direct API connection
  • BigCommerce — OAuth authentication
  • Salsify — API key-based
  • Akeneo — API credentials
  • WooCommerce — REST API
  • Walmart — Vendor API
  • Wayfair — Partner API

​
The Connection Process

​
Step 1: Go to Integrations

Navigate to Workspace → Integrations. [SCREENSHOT: Integrations page main view]

​
Step 2: Click “Add New Integration”

In the Add New Integrations grid, find the platform you want to connect and click its card. [SCREENSHOT: Add New Integrations grid with platform options highlighted]

​
Step 3: Follow Platform-Specific Authentication

Each platform has its own authentication flow. For most, you’ll:
  1. Click Connect or Authenticate
  2. Log in to your account on that platform (you’ll be sent to their login page)
  3. Approve Merchkit’s access request
  4. Return to Merchkit—the connection is established

​
Step 4: Name Your Connection (Optional)

If you have multiple accounts on the same platform, you can label them (e.g., “Shopify US” vs. “Shopify EU”). This helps you remember which is which.

​
Step 5: Review Permissions

Merchkit will confirm which data it can access:
  • Product information
  • Variants and SKUs
  • Custom fields / metafields
  • Pricing
  • Inventory (if needed)
All platform integrations are read-write, so Merchkit can both pull data in and push changes back out. The initial import is read-only until you set up export mapping. [SCREENSHOT: Authentication confirmation screen showing permissions]

​
Your Integration is Now Active

Once authenticated, your integration appears in the Active Integrations list with:
  • Platform name
  • Connection status (Connected)
  • Last sync timestamp (will update after first import)
You won’t be able to import or export data until you’ve set up field mapping. That’s next.

​
Troubleshooting Connection Issues

“Authentication failed”
  • Verify your username and password on the platform
  • Check that the account has API or integration permissions enabled
  • Some platforms require you to generate an API key in your settings first—see platform-specific guides
“Permission denied”
  • Return to the platform’s app permissions settings and grant Merchkit full access to products and variants
  • Some platforms require you to whitelist Merchkit’s IP or domain
“Already connected to this platform”
  • You can only connect one account per platform in Merchkit. If you need to switch accounts, delete the integration and reconnect with the new account.
