How to Integrate Gelato with Customix

  • Go to your Gelato dashboard
  • In the left-hand menu, scroll down and click Developer > API Keys
Create an API

Step 2: Generate Your API Key

The key will grant access to all major Gelato APIs, including:

  • Product catalog discovery
  • Order placement and management

Create key

Step 3: Copy the API Key

  • Once the API key is generated, copy it to your clipboard

Step 4: Connect Gelato to Customix

  • Open the Customix Product Personalizer app in your Shopify admin
  • Go to Settings > Fulfillments
  • Locate the Gelato provider and click to toggle it on
  • Paste your Gelato API key into the prompt and click Update
Apply the API to Customix

How It Works

Once Gelato is integrated:

  • When you create a campaign using a product from the Gelato product base, Customix will automatically link the information
  • When an order is placed, you can click Request Fulfillment
  • The order will be sent to Gelato for production and shipping
  • Once fulfilled, tracking details will be synced back automatically to your Shopify Orders dashboard

This integration ensures that your fulfillment process runs smoothly, reducing manual work and improving delivery efficiency.
