Integration Experiences​

The CCG widget supports two core delivery models. Choose the one that fits your integration needs:

Embedded

Embedded Experience

Embedded Experience — wallet inside merchant portal

The widget renders directly inside your application via inline, modal, or drawer containers — seamlessly integrated with your brand.

  • Display and manage the member's digital wallet
  • Add, edit, or delete saved payment methods
  • Make one-time payments without saving details
  • Guest checkout — no wallet required
  • Supports React and non-React apps
Hosted

Hosted Experience

Hosted Experience — widget as browser pop-up

The widget is served as a CCG-managed browser pop-up launched from your page — minimal frontend code required.

  • Full wallet experience with HealthSafe Pay
  • Guest checkout (one-time payment)
  • Language selector dropdown
  • Quickest setup — no embedding needed
