# Trial Licenses

All licenses have a Boolean field denoting whether it is a trial or not. This can be seen on the license summary as well as the license detail page:

{% hint style="info" %}
By using the `is_trial` Boolean designating a license is of type trial, you have a flag that allows you to configure your software in demo mode.
{% endhint %}

### Particularities of a Trial License

* Trial licenses are the only type of license that can be issued through the License API. In other words, your application can request and activate a trial license without the software vendor's involvement.
* By changing the Boolean value of the `is_trial` field from `True` to `False`, you can upgrade a license.
* Since any license type can also be a trial license, you might notice that a perpetual or a consumption license can also have an expiry date.

{% hint style="info" %}
When a license is a trial license, the expiry date for that license always refers to the trial expiry date.
{% endhint %}

### Setting a Trial Expiration Date Through the Vendor Platform

You can either set a fixed end date, or a set number of days from the first use of the trial license:

Before activation you have two options - you can either set `trial_days` OR `validity_period` on a trial license. If both are defined on a trial license, when this license is activated, `validity_period` will take precedence and License API will use this field and ignore `trial_days`. If only `trial_days` are defined, then `validity_period` will be calculated and used to determine license validity.

Use only `trial_days` if you want the `validity_period` to be calculated at the time of activation based on this number.

Use `validity_period` if you already know, even before activation, until when this license should be valid.

### “Upgrading” a Trial License

Any trial license can be edited to modify the license so that it is no longer a trial license, but a full license for your product. To do so:

{% stepper %}
{% step %}

### Open the license detail page

Open the license detail page for that given trial license and click "Edit License".
{% endstep %}

{% step %}

### Disable trial and save

Uncheck the "Is Trial" box, and click "Save".
{% endstep %}
{% endstepper %}

### Issuing New Trial Licenses

There are a few ways that a trial license can be issued:

* Through the vendor platform on [**Issuing New Licenses**](https://docs.licensespring.com/vendor-platform/licenses/issuing-new-licenses) view
* Through the License API using [**Trial Key**](https://docs.licensespring.com/license-api/trial-key) endpoint
* Through the Management API using [**Create Order**](https://docs.licensespring.com/management-api/order/create-order) endpoint
