# Vue.js integration

Integrate the Access Checkout Web SDK in a Vue.js v2 application.

## Integration

You must add the SDK checkout.js script via JavaScript in the mounted() function of a Vue.js component. You must then add a listener for the load event where you initialize the SDK.

### Full integration example
