# Consul-Terraform-Sync Enterprise License
<EnterpriseAlert>
Licenses are only required for Consul-Terraform-Sync Enterprise
</EnterpriseAlert>
Consul-Terraform-Sync Enterprise binaries require a [Consul Enterprise license](/docs/enterprise/license/overview) to run. There is no Consul-Terraform-Sync Enterprise specific license. As a result, Consul-Terraform-Sync Enterprise's licensing is very similar to Consul Enterprise.
All Consul-Terraform-Sync Enterprise features are available with a valid Consul Enterprise license, regardless of your Consul Enterprise packaging or pricing model.
To get a trial license for Consul-Terraform-Sync Enterprise, you can sign-up for the [trial license for Consul Enterprise](/docs/enterprise/license/faq#q-where-can-users-get-a-trial-license-for-consul-enterprise).
## Setting the License
Choose one of the following methods (in order of precedence) to set the license:
1. Set the `CONSUL_LICENSE` environment variable to the license string.
```shell-session
export CONSUL_LICENSE=<LICENSE_VALUE>
```
2. Set the `CONSUL_LICENSE_PATH` environment variable to the path of the file containing the license.
```shell-session
export CONSUL_LICENSE_PATH=<PATH>/<TO>/<FILE>
```
3. Configure the [`license_path`](/docs/nia/configuration#license_path) option in the configuration file to point to the file containing the license.
```hcl
license_path = "<PATH>/<TO>/<FILE>"
```
~> **Note**: the [options to set the license and the order of precedence](/docs/enterprise/license/overview#binaries-without-built-in-licenses) are the same as Consul Enterprise server agents.
### Updating the License
The previous section describes options for [setting the license](#setting-the-license) needed to start running Consul-Terraform-Sync Enterprise. Use the following procedure to update the license when it expires or is near the expiration date:
1. Update the license environment variable or configuration with the new license value or path to the new license file
1. Stop and restart Consul-Terraform-Sync Enterprise
Once Consul-Terraform-Sync Enterprise starts again, it will pick up the new license and run the tasks with any changes that may have occurred between the stop and restart period.
## Notification and Termination Behavior
Licenses have an expiration date and a termination date. The termination date is a time at or after the license expires. Consul-Terraform-Sync Enterprise will cease to function once the termination date has passed.
The time between the expiration and termination dates is a grace period. Grace periods are generally 24-hours, but you should refer to your license agreement for complete terms of your grace period.
When approaching expiration and termination, Consul-Terraform-Sync Enterprise will provide notifications in the system logs:
| Time period | Behavior |
|---------------------------------------------|-----------------------------------|
| 30 days before expiration | Warning-level log every 24-hours |
| 7 days before expiration | Warning-level log every 1 hour |
| 1 hour before expiration | Warning-level log every 1 minute |
| 1 day before expiration | Warning-level log every 5 minutes |
| At or after expiration (before termination) | Error-level log every 1 minute |
| At or after termination | Error-level log and exit |
~> **Note**: Notification frequency and [grace period](/docs/enterprise/license/faq#q-is-there-a-grace-period-when-licenses-expire) behavior is the same as Consul Enterprise.
