​

Message flow and limits

​

• Default fetch size: 50

​

Message requirements

A message must include at least one of:

• Text content
• A valid URL-style content body

​

Anti-spam protection

Messages can be blocked when they look abusive, including:

• Mention flood
• Excessive zero-width character usage

​

Upload limits

• Message image uploads: up to 5MB
• Supported upload type: images only

​

Reactions, edits, and deletes

• Users can edit/delete their own messages.
• Group owners (or users with manage message permissions) can moderate group messages.
• Reactions are supported for both group and DM messages.

​

Real-time behavior (WebSocket)

Verba live chat uses WebSocket channels for:

• New message events
• Message edits/deletes
• Typing indicators
• Group/DM subscription updates

This is why messages appear instantly across open sessions when everything is healthy.

​

Why a verb did not reply

Common causes:

• The verb was not configured to auto-respond in that context.
• The message was blocked by anti-spam rules.
• The sender does not have permission to post in the group.
• The verb or channel settings limit responses.
