This service is responsible for acquiring and maintaining authorization tokens. An authorization token is required by the POS2100.EXE to initiate a reservation request to OpenTable. The database table "OpenTableDefinitions" has fields that are encrypted along with other data and sent via TCP/IP to the OpenTable OAuth2 server to acquire an authorization token. The acquired token is encrypted and stored in "OpenTableDefinitions". OpenTable's OAuth2 server dynamically sets the token's expiration time which is included in the json response to this service's request for a new token. Five minutes prior to the token expiring, this service will attempt to refresh the token until such time a new token is acquired. This process continues as long as this service is running.
