# License key • What if a customer purchases a license key that is not in stock anymore? If your customer purchases a digital product with one of your own license keys BUT you've ran out of license key, the following will happen: * your customer will be notified the license key will be sent soon * you, the merchant, will see an alert under the "license key" tab saying one (or several) customers are waiting for their license keys to be sent. * you, the merchant, will be able to add license keys then you'll find a button to send said license key to your waiting customers --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
