License Lifecycle

The diagram below depicts a possible lifecycle of a third-party license
in Key Administrator:

Step by step description of the above diagram:

  1. First, a license is created as a “Basic” edition. This happens on
    March 12, 2016. This involves the License Creation/Renewal/Upgrade
    Request
    call (the PURCHASE action) from KA to the
    ISV endpoint.

    • The next license renewal date is evaluated as the creation date +
      1 month, which is April 12, 2016. This is the date when the
      license should be renewed (i.e., prolonged for the next 1 month).

    • The license expiration date is evaluated as the creation date + 1
      month + 10 days, which is April 22, 2016.

      Note: If renewal is not possible (this may happen if the ISV endpoint
      is unavailable, or there are network issues that prevent
      successful connection to the ISV endpoint), then KA will repeat
      attempts to renew the license the next day after the “planned”
      renewal date, and then again and again during 10 days, until
      either the license is successfully renewed or the license
      expiration date is reached. In the latter case, the license
      becomes “expired” and no further attempts to renew it are made.

  2. The license is renewed by 1 month. This involves the License
    Creation/Renewal/Upgrade Request
    call (the RENEW
    action) from KA to the ISV endpoint.

    • The next renewal date is shifted 1 month ahead, which is May 12,
      2016.
    • The expiration date is shifted 1 month ahead, which is May 22,
      2016.
  3. The license is renewed by 1 month again. This involves one more
    License Creation/Renewal/Upgrade Request call (the
    RENEW action).

    • The next renewal date is shifted to June 12, 2016.
    • The expiration date is shifted to June 22, 2016.
  4. The License is upgraded from the “Basic” to the “Pro” edition. This
    involves the License Creation/Renewal/Upgrade Request
    call (the UPGRADE action).

    • The license dates remain unchanged.

    • The license body is updated with a newer data returned from the
      ISV endpoint. Now, the license body contains a key that will
      unlock the “Pro” functionality for the end user.

      Note: Upgrade of a third-party license makes sense if there are
      multiple sales options available. So if a customer has
      initially purchased a license for the “lowest” option, they can
      upgrade their license to a “higher” option later. Example:
      Bronze -> Silver -> Gold.

  5. The license is renewed by 1 month again. This involves the License
    Creation/Renewal/Upgrade Request
    call (the RENEW
    action).

    • The next renewal date is shifted to July 12, 2016.
    • The expiration date is shifted to July 22, 2016.
  6. Finally, the license is terminated. This involves the License
    Termination Request
    call.

    Note: Please note that the License Creation/Renewal/Upgrade
    Request
    calls to the ISV endpoint are also used to
    update the body of the license record stored in Key Administrator.
    The License Termination Request call is not used
    for this purpose.
