# API/REST Interface Description CoderBridge The Coder Bridge Software will run on the Messerschmitt System PC, locally in the hotel. It is a simple Webserver and provides a REST API. The REST Interface uses JWT(JSON Web Token) as Authentication. The communication between an external Service(PMS Service) and the Bridge will be done, depending on the needs, in 2 or 4 steps: 1. Authentication with JWT 2. Get the Messerschmitt Checkout Times 3. Get the Messerschmitt Special Areas 4. Request a GuestKey or Mobile Key or CheckinRoom(RMS) or Read a Card 1. Checkin Room 2. Checkout Room 3. Request a Guestkey 4. Checkout GuestKey 5. Request a PreCheckin Guestkey 6. Request a MobileKey 7. Request a MobileKey using PushService 8. Read a Card 9. Examples The steps 2 and 3 are optional. If there is no need to overwrite the hotels system standards, this functions have not to be called. In this case the standard values, defined in the Messerschmitt Database will be used. **Note:** normally there is no need to perform the steps 2 & 3 everytime requesting a guestkey or mobilekey. So storing this values temporary in memtables or something is recommended. ## General information and credentials The Coder Bridges webservice will be reachable via the Messerschmitt System PCs IP address and the Port 7331. The sub-path for the service is 'mst/enc' e.g.: > URL: http://192.168.15.67:7331/mst/enc ... **CLIENT ID AND PASSWORD FOR THE JWT AUTHENTICATION WILL BE CONCLUDED DURING INSTALLATION AND CONFIGURATION**
