# Module types

## Module types <a href="#module-types" id="module-types"></a>

Modules should be associated with the correct type depending on their functionality.

Detailed descriptions of different types of modules can be found in our [modules](https://developers.make.com/custom-apps-documentation/app-components/modules) documentation as well as in the [best practices guide to module descriptions](https://developers.make.com/custom-apps-documentation/best-practices/naming-conventions/modules/module-descriptions).

## Universal modules

Each app should have a universal module. This module allows users to use API endpoints that are not supported, using their connection created to the app.

More about universal modules can be found in our [modules](https://developers.make.com/custom-apps-documentation/app-components/modules/universal-module) documentation.

Make sure the universal module has the:

* correct label and description,
* correct `url` which starts with the [base URL](https://developers.make.com/custom-apps-documentation/app-components/base/base-url), and
* correct connection.
