Supported Modification Types

    "subtitle": "Up to 50% off all items",
    "cta_text": "Shop Now"

  }
}

Response Fields

Supported Style Properties

When using dot notation for style updates, the following properties are commonly supported:

Error Responses

Cache Invalidation

When modifications are applied:

1. Template render cache is automatically invalidated
2. Dynamic URL cache for the template is cleared
3. Subsequent render requests will use the updated content

Best Practices

1. Use Parameter IDs: Ensure your template has parameterId set on elements you want to update
2. Batch Updates: Combine multiple page modifications in a single request to reduce API calls
3. Validate URLs: Ensure image URLs are accessible and return valid images
4. Error Handling: Always check the failed array in responses for partial failures
5. Style Consistency: When updating styles, ensure values are compatible with the element type
