# In-app Templates Overview

> Create, search, and update In-app templates (Self-Handled and HTML).

The MoEngage In-app Templates API allows you to seamlessly manage In-app templates within the MoEngage platform. This API enables you to upload templates created outside the MoEngage ecosystem—supporting both **Self-Handled** and **HTML** types—so they can be used for campaign creation.

With these endpoints, you can create versions of your templates, search through your existing library using various filters, and choose whether updates to a template should automatically reflect in your active campaigns.

## Endpoints

The In-app Templates API is a collection of the following endpoints:

* [Create In-app Template](/api/in-app-templates/create-in-app-template): Creates a new In-app template (Self-Handled or HTML).
* [Update In-app Template](/api/in-app-templates/update-in-app-template): Updates an existing template.
* [Search In-app Templates](/api/in-app-templates/search-in-app-templates): Finds templates using filters like name, source, type, or creator ID.
