Json-RPC 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.

Credentials
-----------

The API credentials are available on the settings page.

- API end-point: `http://YOUR_SERVER/jsonrpc.php`
- Username: `jsonrpc`
- Password: Random token (API token on the settings page)

The API use the [HTTP Basic Authentication Scheme described in the RFC2617](http://www.ietf.org/rfc/rfc2617.txt).
If there is an authentication error, you got an HTTP status code `401 Not Authorized`.

Examples
--------

### Example with cURL

From the command line:

```bash
curl \
-u "jsonrpc:19ffd9709d03ce50675c3a43d1c49c1ac207f4bc45f06c5b2701fbdf8929" \
-d '{"jsonrpc": "2.0", "method": "getAllProjects", "id": 1}' \
http://localhost/kanboard/jsonrpc.php
```

Response from the server:

```json
{
    "jsonrpc":"2.0",
    "id":1,
    "result":[
        {
            "id":"1",
            "name":"API test",
            "is_active":"1",
            "token":"6bd0932fe7f4b5e6e4bc3c72800bfdef36a2c5de2f38f756dfb5bd632ebf",
            "last_modified":"1403392631"
        }
    ]
}
```

### Example with a PHP client:

I wrote a simple [Json-RPC Client/Server library in PHP](https://github.com/fguillot/JsonRPC), here an example:

```php
<?php

$client = new JsonRPC\Client('http://localhost:8000/jsonrpc.php');
$client->authentication('jsonrpc', '19ffd9709d03ce50675c3a43d1c49c1ac207f4bc45f06c5b2701fbdf8929');

print_r($client->getAllProjects());

```

The response:

```
Array
(
    [0] => Array
        (
            [id] => 1
            [name] => API test
            [is_active] => 1
            [token] => 6bd0932fe7f4b5e6e4bc3c72800bfdef36a2c5de2f38f756dfb5bd632ebf
            [last_modified] => 1403392631
        )

)
```
