+Json-RPC API
+============
+
+User and application API
+------------------------
+
+There are two types of API access:
+
+### Application API
+
+- Access to the API with the user "jsonrpc" and the token available on the settings page
+- Access to all procedures
+- No permission checked
+- There is no user session on the server
+- No access to procedures that starts with "My..." (example: "getMe" or "getMyProjects")
+- Example of possible clients: tools to migrate/import data, create tasks from another system, etc...
+
+### User API
+
+- Access to the API with the user credentials (username and password)
+- You can also generate a personal access token instead of your password
+- Application role and project permissions are checked for each procedure
+- A user session is created on the server
+- Example of possible clients: native mobile/desktop application, command line utility, etc...
+
+Security
+--------
+
+- Always use HTTPS with a valid certificate (avoid clear text communication)
+- If you make a mobile application, it's your responsability to store securely the user credentials on the device
+- After 3 authentication failure on the user api, the end-user have to unlock his account by using the login form
+- Two factor authentication is not yet available through the API
+
+Protocol
+--------
+
+Kanboard use the protocol Json-RPC to interact with external programs.
+
+JSON-RPC is a remote procedure call protocol encoded in JSON.
+Almost the same thing as XML-RPC but with the JSON format.
+
+We use the [version 2 of the protocol](http://www.jsonrpc.org/specification).
+You must call the API with a `POST` HTTP request.
+
+Kanboard support batch requests, so you can make multiple API calls in a single HTTP request. It's particularly useful for mobile clients with higher network latency.
