Create Trial Key - Devolens (formerly Cryptolens) Documentation

This method creates a license key that is time-limited, node-locked and with the “Time-Limited” and “Trial” features set to true (which can be set by editing the feature definitions on the product page). Note, by default, the trial will work for 15 days. To change this limit, you can set the Feature Lock to the desired value, when creating the access token. If a trial key was already created for a certain machine code, this method will try to find the license key and return it instead. However, this will only occur if the license key is still a trial key (based on feature definitions) and is not blocked. This method is accessed by https://api.cryptolens.io/api/key/CreateTrialKey
