# Usage

The Frontend API works in many Ways similar to the Media APIs. Many of the common Parameters are valid here also, wherever possible.

{% hint style="info" %}
Please notice, that all the following Endpoints are intended for Frontend Operations and need a valid Session.
{% endhint %}

To control an API Session, you will need the following Endpoints:

{% content-ref url="endpoints/session-endpoint" %}
[session-endpoint](https://api.docs.nexx.cloud/frontend-api/endpoints/session-endpoint)
{% endcontent-ref %}

In many Cases, Users interact with Media Objects (like, comment, rate etc). To handle these Cases, use the Media Interaction API:

{% content-ref url="endpoints/interaction-endpoint" %}
[interaction-endpoint](https://api.docs.nexx.cloud/frontend-api/endpoints/interaction-endpoint)
{% endcontent-ref %}

If your Domain uses a nexxOMNIA User Model, the registered User has a lot of Options for his Profile and Activities:

{% content-ref url="endpoints/user-endpoint" %}
[user-endpoint](https://api.docs.nexx.cloud/frontend-api/endpoints/user-endpoint)
{% endcontent-ref %}

If your Domain uses a nexxOMNIA Payment Model, the Payment Processing Endpoints can be found here:

{% content-ref url="endpoints/payment-endpoint" %}
[payment-endpoint](https://api.docs.nexx.cloud/frontend-api/endpoints/payment-endpoint)
{% endcontent-ref %}
