# Endpoints

Frontend Operations can take place in easy or complex Scenarios. In any Case, you must have a valid Frontend Session:

{% content-ref url="/pages/-M9bgIaAG6MxGVRdvLvk" %}
[Session Management](/frontend-api/endpoints/session-endpoint.md)
{% endcontent-ref %}

If you only want to enable simple User Interactions like Rating or Comments, start with Media Interactions:

{% content-ref url="/pages/-M9bgBxbOnBPT1XiALLJ" %}
[Media Interactions](/frontend-api/endpoints/interaction-endpoint.md)
{% endcontent-ref %}

If you are using the nexxOMNIA User Model too, you will need the User Endpoint for Profile Management and User defined Content:

{% content-ref url="/pages/-M9bgK\_52KjU9VI1bm\_m" %}
[User Endpoint](/frontend-api/endpoints/user-endpoint.md)
{% endcontent-ref %}

And in the most complex Cases, you will also use the nexxOMNIA Payment APIs. You will find the Details of them here:

{% content-ref url="/pages/-M9bgMjFmPNSDxtrlddF" %}
[Payment Processing](/frontend-api/endpoints/payment-endpoint.md)
{% endcontent-ref %}
