Opcodes and status codes

Opcodes and Status Codes

Gateway

All gateway events in Discord are tagged with an opcode that denotes the payload type. Your connection to our gateway may also sometimes close. When it does, you will receive a close code that tells you what happened.

Gateway Opcodes

Code	Name	Client Action	Description
0	Dispatch	Receive	An event was dispatched.
1	Heartbeat	Send/Receive	Fired periodically by the client to keep the connection alive.
2	Identify	Send	Starts a new session during the initial handshake.
3	Presence Update	Send	Update the client’s presence.
4	Voice State Update	Send	Used to join/leave or move between voice channels.
6	Resume	Send	Resume a previous session that was disconnected.
7	Reconnect	Receive	You should attempt to reconnect and resume immediately.
8	Request Guild Members	Send	Request information about offline guild members in a large guild.
9	Invalid Session	Receive	The session has been invalidated. You should reconnect and identify/resume accordingly.
10	Hello	Receive	Sent immediately after connecting, contains the heartbeat_interval to use.
11	Heartbeat ACK	Receive	Sent in response to receiving a heartbeat to acknowledge that it has been received.
31	Request Soundboard Sounds	Send	Request information about soundboard sounds in a set of guilds.

Gateway Close Event Codes

In order to prevent broken reconnect loops, you should consider some close codes as a signal to stop reconnecting. This can be because your token expired, or your identification is invalid. This table explains what the application defined close codes for the gateway are, and which close codes you should not attempt to reconnect.

Code	Description	Explanation	Reconnect
4000	Unknown error	We’re not sure what went wrong. Try reconnecting?	true
4001	Unknown opcode	You sent an invalid Gateway opcode or an invalid payload for an opcode. Don’t do that!	true
4002	Decode error	You sent an invalid payload to Discord. Don’t do that!	true
4003	Not authenticated	You sent us a payload prior to identifying, or this session has been invalidated.	true
4004	Authentication failed	The account token sent with your identify payload is incorrect.	false
4005	Already authenticated	You sent more than one identify payload. Don’t do that!	true
4007	Invalid seq	The sequence sent when resuming the session was invalid. Reconnect and start a new session.	true
4008	Rate limited	Woah nelly! You’re sending payloads to us too quickly. Slow it down! You will be disconnected on receiving this.	true
4009	Session timed out	Your session timed out. Reconnect and start a new one.	true
4010	Invalid shard	You sent us an invalid shard when identifying.	false
4011	Sharding required	The session would have handled too many guilds - you are required to shard your connection in order to connect.	false
4012	Invalid API version	You sent an invalid version for the gateway.	false
4013	Invalid intent(s)	You sent an invalid intent for a Gateway Intent. You may have incorrectly calculated the bitwise value.	false
4014	Disallowed intent(s)	You sent a disallowed intent for a Gateway Intent. You may have tried to specify an intent that you have not enabled or are not approved for.	false

HTTP

Our API will return semantically valid HTTP response codes based on the success of your request. The following table can be used as a reference for response codes it will return.

HTTP Response Codes

Code	Meaning
200 (OK)	The request completed successfully.
201 (CREATED)	The entity was created successfully.
204 (NO CONTENT)	The request completed successfully but returned no content.

5xx (SERVER ERROR)	The server had an error processing your request (these are rare).

JSON

Along with the HTTP error code, our API can also return more detailed error codes through a code key in the JSON error response. The response will also contain a message key containing a more friendly error string. Some of these errors may include additional details in the form of Error Messages provided by an errors object.
