Every request, call, event and field a bot can use. For a walk through making a bot, start with Building a bot.

This page is written out from the server's own code by tools/apiref.mjs, so the names, fields and types are the ones the server uses. Change that file, not this page.

• Address: https://api.maplecord.app. Requests are under /api/; the live connection is at /hubs/chat.
• Token: every request carries Authorization: Bot <token>. The live connection is a SignalR connection whose access token is bot:<token>.
• Bodies and answers are JSON. Field names are camelCase.
• IDs are GUIDs, written as text. Times are ISO 8601 text, in UTC.
• Kinds (of message, of channel, and so on) are sent as numbers. The tables under Kinds say which number is which.
• Errors come back as { "error": "..." } with a status that fits: 400 the request was wrong, 401 no token or a bad one, 403 not allowed, 404 not there or not visible to the bot, 413 too large, 429 too fast.
• Something missing or hidden answers 404 either way: a bot is not told that a channel it cannot see exists.
• P2P channels: nothing in them goes through the server, so none of this reads or posts there.
• GET /api/meta needs no token. Among other things it says whether the live connection must go straight over a WebSocket (webSocketsOnly).

What	Limit	Past it
Requests	600 a minute for each bot	429 with a Retry-After header
Posting with a request, and posting, editing, reacting, pinning and voting over the live connection, all together	10 in any 10 seconds	A request gets 429 with a Retry-After header; a call fails: "You are doing that too fast"
Other calls on the live connection	800 in any 10 seconds	The same
A webhook	30 posts a minute	429
One message over the live connection	128 KB
A message	4000 characters	400

What a bot can call. A call that is refused fails with the reason as its message.

Call	What it does	Answer
QueuePlace()	Where this connection stands in the line to get in, when the server is full; null when it is in. Ask it before Ready: on a connection that is waiting nothing else is answered, and plain requests are answered 503. When Admitted arrives, connect afresh.	QueuePlaceDto, or null

Vote(messageId, options)	Votes in a poll: the numbers of the choices picked, counting from 0. An empty list takes the vote back. messageId: ID; options: list of number.
ClosePoll(messageId)	Closes a poll: one the bot started, or anyone's with Manage messages. messageId: ID.
SetTyping(channelId)	Shows the bot as typing in a channel for a few seconds. channelId: ID.

Connection() answers this connection's own ID as text. It is only needed when webSocketsOnly is true.
