Text Chat Developer Guide

Vivox provides two tiers of text chat service:

• Standard text chat - channel-based and directed text chat.

  • Chat messages can contain any language or content up to service-defined size and rate limits.

  • Chat messages are transported over TLS. No chat messages are saved or archived.

• Text chat with transient channel message history - a predefined number of chat messages sent to a channel are kept in memory so newly joined users can see the most recent messages. After the channel empties, the channel message history is immediately lost.

The server can customize a maximum byte count for text messages in its pre-login configuration. By default, the maximum is 320 bytes with UTF-8 encoding. A text message that exceeds the maximum length in bytes is rejected with a VxErrorMessageTextTooLong error.

The following table details text chat policy options:

Service	Policy option	Default	Description
Standard text chat	rate_limit	1000 bytes per second	The maximum rate at which a player can send data over text chat. This is configured server-side by Vivox.
Channel message history	history_size	0 messages	The maximum number of messages a channel keeps in memory. This is configured server-side by Vivox.
