How to Integrate Gelato with Customix

Step 1: Log in to the Gelato Developer Dashboard

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

Step 2: Generate Your API Key

Click Add API Key
Enter a Name for the API key
Click Create Key
The key will grant access to all major Gelato APIs, including:
Product catalog discovery
Order placement and management
Product and shipment prices

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

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.
