# Using Junction API

> Use the Junction API to manage patients and access Junction's team-scoped platform capabilities.

Use the [Junction API](/api-details/junction-api) alongside Junction Connect to work with patient and clinical data in a team.

<Info>
  To create, retrieve, and update patients and their demographics, see [Managing Patients](/api-reference/org-management/connect/managing-patients).
</Info>

Authenticate Junction API requests using one of its [team-scoped authentication methods](/api-details/junction-api#authentication):

* Authenticate with a **Team API Key**.
* Authenticate with a **Team API Access Token** created through the [Create Team API Access Token](/api-reference/org-management/team-api-access-token/create-team-api-access-token) endpoint.

Through the Junction API, you can:

* manage users and demographics information in your Team with the [Core API](/api-reference/user/create-user);
* manage user connections, pull ingested device data, inspect connection backfill statuses through the [Devices API](/wearables/connecting-providers/introduction);
* order lab tests, manage appointments and pull the results through the [Lab Testing API](/lab/overview/introduction); and
* aggregate ingested device data with the [Junction Sense API](/sense/overview).

See the [Junction API overview](/api-details/junction-api) for links to each API category, available environments, regional endpoints, and authentication options.
