# Legacy: Marqeta Widgets

> Documentation for the deprecated Marqeta widget integrations.

<Warning>
  Marqeta is sunsetting their Marqeta.js widget library. We recommend migrating to [Synctera Widgets](/v2/docs/card-widgets#synctera-widgets-recommended) for new integrations.

  The Marqeta widgets documented in this section will continue to work during the transition period, but new integrations should use Synctera Widgets.
</Warning>

## Overview

The legacy Marqeta widgets provide card functionality through two integration methods:

1. **Marqeta.js Library** - For displaying sensitive card data (PAN, CVV, EXP, PIN)
2. **Marqeta Widget URLs** - For card activation and PIN setting via iframes

## Why Migrate?

Synctera Widgets offer several advantages over the legacy Marqeta widgets:

| Feature              | Marqeta Widgets             | Synctera Widgets             |
| -------------------- | --------------------------- | ---------------------------- |
| **Integration**      | iframe URLs or JS bootstrap | Web Components               |
| **Customization**    | Limited CSS styling         | Full theming + custom labels |
| **Event Handling**   | Callback functions          | Standard DOM events          |
| **Token Management** | Multiple token types        | Unified widget token         |
| **Future Support**   | Being sunset                | Actively maintained          |

## Recommendation

* **New integrations**: Use [Synctera Widgets](/v2/docs/card-widgets#synctera-widgets-recommended)
* **Existing integrations**: Plan migration using the [Migration Guide](/v2/docs/card-widgets-legacy-migration)
* **Reveal Card functionality**: Use [Synctera Reveal Card Widget](/v2/docs/card-widgets-reveal)
