# Channel extension

For a channel to remain active and functional, timely extension is key. Initially, upon creation, every channel enters a Trial mode, which lasts for 5 days. Post-Trial, the channel ceases to operate unless extended.

{% hint style="success" %}
If you subscribe to channels on your own, there is no need to extend channels as this will be done automatically.
{% endhint %}

To facilitate this, a specific method exists that allows days to be transferred from an account's balance to the channel. For instance, adding 30 days extends the channel's active period by a month, ensuring uninterrupted service up to the extended date.

{% hint style="info" %}
Some of our partners opt to charge daily for the service, automating channel extensions day by day to match their billing cycle.
{% endhint %}

The channel will run until the date you extend the channel to

The `comment` parameter is required, but it is done for convenience, you can type anything here. This information is displayed on the [Billing History page](https://panel.whapi.cloud/billing/history).
