Lock

Lock a session to prevent bookings.

When invoking Lock with a sessionId, the session can no longer be booked or checked out unless the returned key is passed in the request. Lock returns a key that can also be used with Unlock to re-enable booking and checkout for the given session.

Once a session is locked:

• When calling Is Available, the returned value of the available property is false.
• Calling Book or Checkout will fail unless the correct key is passed in the request.
