# Plan APIs

This feature is in a closed beta phase and is available upon request only for Enterprise partners. Talk to us to learn more.

## Overview <a href="#h_b13fc7bc5d" id="h_b13fc7bc5d"></a>

The foundation of the Aphex Planner data model are projects and tasks. Tasks reflect planned work and crucial properties such as subcontractors or shifts.

For customers and partners wanting to build external or internal applications and workflows on top of planned tasks, we provide a broad set of endpoints that give access to real-time data from a Plan workspace.

Typically use cases for these endpoints include;

* Third-party platforms and products building integrations to Aphex
* Internal customer teams using planned tasks as the trigger for internal apps or workflows

## Querying the Plan APIs <a href="#query" id="query"></a>

Our APIs follow the essence of REST and all queries must be made via HTTPS to pass the endpoint security rules.

Endpoints query rules and response structure can be accessed from the following page;

<table data-view="cards"><thead><tr><th></th><th></th><th></th></tr></thead><tbody><tr><td></td><td><a data-mention href="/pages/MhJaNenTuhYVOeHn86SZ">/pages/MhJaNenTuhYVOeHn86SZ</a></td><td></td></tr><tr><td></td><td><a data-mention href="/pages/JIpUX1aUyQZN5J5nVtI3">/pages/JIpUX1aUyQZN5J5nVtI3</a></td><td></td></tr><tr><td></td><td><a data-mention href="/pages/FrlJtktJ6lklRmnfhnWM">/pages/FrlJtktJ6lklRmnfhnWM</a></td><td></td></tr></tbody></table>
