### CrossEngage Architecture

CrossEngage Products are built on a Web-Oriented Architecture. This means that you do not need any installations or setup on your device(s), as all processing is done on our Servers. You can use an up-to-date web browser to access our products.

{% hint style="info" %}
We recommend using Google Chrome for CrossEngage products.
{% endhint %}

Additionally, CrossEngage provides APIs to interact with our servers and databases. Once you have your API keys (from your System Setup), you can use any API Client or write your own code to hit the API endpoints. In this documentation, we use Postman and Insomnia as API Clients.
