# Introduction to Link

> Introduction to Junction Link, the mechanism for connecting user wearable accounts to Junction as a hosted widget or custom API integration.

Junction Link enables your users to connect their accounts with [supported cloud-based providers](/wearables/providers/introduction)
to Junction.

Junction Link is offered in two forms:

* [Junction Link Widget](/wearables/connecting-providers/link_flow) is a web flow hosted by Junction, providing a complete
  provider connection wizard UX that is ready to integrate.

* [Junction Link API](/wearables/connecting-providers/custom_widget) allows you to build your own Link Widget-like user experience.

<Warning>
  Junction Link API covers **only** [cloud-based providers](/wearables/providers/introduction#cloud-based-providers).

  Your mobile app has to manage connections with SDK-based providers — such as Apple HealthKit and Android Health
  Connect — through the [Junction Mobile Health SDK](/wearables/sdks/health/overview), separately from Junction Link.
</Warning>
