Activation is an entity that represents a certain License activation. Licenses can be activated multiple times as long as the limit allows or unlimited times.
Activation token is a unique identifier for each Activation entry in the database which can be used to validate, deactivate or download software assigned to the License and the purchased Product.
Each activation is stored separately in the database. You can activate one License in various places and each activation will be stored in its own row as long as the activation count allows.
Note: Activations could not be created from the WordPress admin or Digital License Manager screens because it doesn’t make sense to do so, but, they can be added through the REST API.
Note: Developers can call the REST API to activate specific License and if validation is OK the API will return activation token which needs to be stored somewhere securely for future access to the Software API.
