Getting Started with Custom Integrations

Last updated: October 16, 2026

Customily offers several ways to integrate personalization into your ecommerce platform.

Important: API integrations require a compatible plan

Our standard $49/month plan does not support API integrations. You'll need to upgrade to an API-compatible plan to use this integration.

Contact our support team for more information at support@customily.com.

Standalone Integration

Integrate Customily into any ecommerce platform using an iframe-based approach. Customily handles the personalization experience, including the live preview and option set form. The iframe can host the complete experience or run in options-only mode when the preview is embedded directly into your page.
