# Testing API locally

To test API locally, you need a test License Key.

1. Head over to console.cal.dev and create a free account. 
2. Create a testing (license) key.
3. When asked for payment here in test mode, you can enter the Stripe testing card `4242 4242 4242 4242` <br>

4. Copy over the test license key and paste it in as your `CALCOM_LICENSE_KEY` env variable's value &#x20;
5. Now, head over to your localhost webapp (not localhost API) and log in to an account.
6. Go to `settings/developer/api-keys` and create a new API key.
7. Give it a name and set the expiration settings, click Save.<br>

8. You should see the generated API key, make sure to copy it and store in a safe location as you will **NOT** be able to recover an API key once lost, only create new ones
