# License States

Each license in Key Administrator can be in one of the four possible states:

1. Active - an active, usable license.
2. Suspended - a license is temporarily disabled. Typically this is done to stop suspicious activity with this license, if such is detected.
3. Expired - a license was not renewed on time and, therefore, became expired. Typically, this happens when a customer who uses pre-paid scheme does not pay on time.
4. Terminated - the final state. A canceled, unusable license with no possibility to revert changes back.

The diagram below demonstrates transitions between the license states:

Only the following license actions from the diagram above involve calls from KA to the ISV endpoint over the ISV protocol:
