The backend API provides additional possibilites on top of the frontend API. To use this API, the tapp must be registered in the Tapp administration in the TSPN. After the registration the Tapp Secret is needed for the authorization on requests to the API.

The requests in frontend and backend have the same structure. For the authorization you can use the Tapp Secret along with the TappID in the backend or a PageAccessToken in the frontend.

The request structure looks like

https://api.chayns.net/{APIVersion}/{LocationID}/{Controller}/{ObjectID}

(the ObjectID parameter is optional).

General parameters explained

• APIVersion - string: Compound of the letter 'v' and the API version. So the parameter could look like 'v2.0'.
• LocationID - int: The ID of the current location. It is contained in chayns.env.site.locationId.
• TappID - int: The ID of the current tapp. It is contained in chayns.env.site.tapp.id and used in the Authorization header.
