JSON-RPC:Technical documentation

This is the technical documentation for JSON-RPC for developers and people who want to interact with UnrealIRCd via the JSON-RPC API. It assumes you have read and configured your UnrealIRCd according to the JSON-RPC article.

Below we talk about the PHP library (optional, in case you use PHP) and then explain the transports that are available (domain sockets, HTTPS POST and websockets), the JSON-RPC protocol and finally all the methods / API calls that are available (currently more than 40 API calls).

PHP library
This wiki page talks about all the inner details of JSON-RPC. But, if you use PHP then it makes more sense to use our library at https://github.com/unrealircd/unrealircd-rpc-php that already does all the work for you.

This PHP library is also used by the webpanel, it allows easy interfacing with UnrealIRCd through regular PHP code, such as:

use UnrealIRCd\Connection;

$api_login = 'api:apiPASSWORD'; // same as in the rpc-user block in UnrealIRCd

$rpc = new UnrealIRCd\Connection("wss://127.0.0.1:8600/",                   $api_login,                    Array("tls_verify"=>FALSE));

$bans = $rpc->serverban->getAll; foreach ($bans as $ban) echo "There's a $ban->type on $ban->name\n";

$users = $rpc->user->getAll; foreach ($users as $user) echo "User $user->name\n";

$channels = $rpc->channel->getAll; foreach ($channels as $channel) echo "Channel $channel->name ($channel->num_users user[s])\n";

Sadly, our PHP library is currently lacking documentation, so the other info on this page could still be of help. Or just to get a better understanding of all the functionality and inner details.

UNIX domain socket
This is for local connections only. On the server side you have this: listen { file "/home/xyz/unrealircd/data/rpc.socket"; options { rpc; } } NOTE: UnrealIRCd 6.0.6+ has this listen block by default when  is included.

Then simply connect to the socket and you can issue JSON-RPC requests directly. Example: $ nc -U ~/unrealircd/data/rpc.sock {"jsonrpc": "2.0", "method": "channel.list", "params": {}, "id": 123} {"jsonrpc": "2.0", "method": "channel.list", "id": 123, "response": {"list": []}}

There is no authentication being done, as only local users can use this and the socket is only readable/writable by the user running UnrealIRCd by default (rwx--).

Each request should end with a newline (an enter). You can issue multiple requests (even in parallel, no need to wait for the response). The connection is not closed. The connection is only closed if some fatal JSON parsing error is encountered such as a missing. Normally that should never happen. Other errors such as an unknown method being called, invalid parameter count, etc. are not fatal.

HTTPS POST
On the server side this requires you to open up a port (Listen block) and add at least one api user (Rpc-user block): listen { ip *; port 8000; options { rpc; } }

rpc-user apiuser { match { ip 192.168.*; } password "password"; }

Then do a  request to   with the JSON request. You must do this over.

Example: curl -s --insecure -X POST -d '{"jsonrpc": "2.0", "method": "channel.list", "params": {}, "id": 123}' https://apiuser:password@127.0.0.1:8000/api The connection is closed after processing the request. If you want to issue another API call then do a new HTTPS POST. If you want streaming requests/responses, use HTTPS Websocket (see next section).

HTTPS Websocket
On the server side the config is the same as for HTTPS POST. You open up a port (Listen block) and add at least one api user (Rpc-user block): listen { ip *; port 8000; options { rpc; } }

rpc-user apiuser { match { ip 192.168.*; } password "password"; }

Now make a HTTPS websocket connection (not HTTP!) to https://localhost:8000/ and:
 * Add a header with "Authorization" type "Basic" that includes your user:pass, so apiuser:password in this case. We do it like this in the unrealircd-rpc-php library.
 * Naturally, localhost will never have a valid TLS certificate so you may need to disable certificate checking. If you use the websocket over the internet to a real host like irc1.example.org then you better keep TLS certificate checks enabled, of course!

Once the websocket connection is established you can send JSON requests. Each request goes into its own websocket frame, eg: {"jsonrpc": "2.0", "method": "channel.list", "params": {}, "id": 123} The connection is kept open so you can issue more JSON-RPC requests. You may also send multiple requests in parallel (each in their own websocket frame), you don't have to wait for a response. Every response will be in their own websocket frame as well.

The connection is only closed upon:
 * A fatal error, such as a JSON parsing error. Obviously this should never happen.
 * When the client does not respond to a websocket PING in time (as required by the websocket specification). Note that browsers automatically PONG back upon PING, so you don't have to worry about it there.

JSON-RPC Methods
The following methods are currently implemented in the git version (with links to documentation!):
 * rpc: ,
 * stats:
 * user:,  ,  ,  ,  ,  ,  ,  ,
 * server:,  ,  ,  ,
 * channel:,  ,  ,  ,
 * server_ban:,  ,  ,
 * server_ban_exception:,  ,  ,
 * spamfilter:,  ,  ,
 * name_ban:,  ,  ,

All the documentation for this is also viewable via the JSON-RPC Methods category
