 ====== SyCes API ====== ====== SyCes API ======
-based on Json RPC via HTTPS+=== Requirements === 
 +Only regular clients can use the API. Furthermore you require an api-key. We will also store a default tariff and the default type of username if you specify them. 
 + 
 +=== Protocol === 
 +Our  [[en:syces:api_hidden:rpcs| SyCes-API]]  uses the JSON-RPC protocol, version 2.0. 
 + 
 +JSON-RPC (JavaScript Object Notation Remote Procedure Call) is a simple remote procedure call protocol encoded in JSON. 
 + 
 +You must call the [[en:syces:api_hidden:rpcs| API]]  via HTTPS. 
 + 
 +=== Usage === 
 +== Request == 
 +Clients need to send a request object to our server with  
 +the following properties: 
 + 
 +  * jsonrpc: a string containing the JSON RPC version, currently "2.0" 
 +  * method: a string with the name of the method to be invoked 
 +  * params: an array of objects to be passed as parameters to the defined method 
 +  * id: a unique string to match the response with the request that it is replying to 
 +(could be a combination of sessionid + sequence) 
 + 
 +== Response == 
 +the response object contains the following properties 
 + 
 +  * jsonrpc: a string containing the JSON RPC version, currently "2.0" 
 +  * result:  If no error occurred, the data returned by the invoked method. Else no result is sent. 
 +  * error:  if there was an error,a specified error code, otherwise no error is sent. 
 +  * id: the id of the request it is responding to 
 +    
 +=== Authentication === 
 +You need to a valid token for any api call. It can be retrieved by calling the authenticate-method. 
 + 
 +=== Examples === 
 +request { "jsonrpc": "2.0", "method": "authenticateByRealm", "params": {"api_key": "231af78...", "realm": "clientdomain.de"}, "id": 1}\\ 
 +result for valid credentials { "jsonrpc": "2.0", "result": {"token": "0252rkcf5jm2rop8rtbnno4og5"}, "id": 1}\\ 
 +result for invalid credentials { "jsonrpc": "2.0", "code": 20, "error": {"message": "Invalid credentials."}, "id": 1} 
 + 
 +=== Example using curl === 
 +curl -i -k -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d '{"jsonrpc": "2.0", "method": "authenticateByRealm", "params": {"api_key": "abc...", "realm": "clientdomain"}, "id": 1}' 'https://host:port'
