The Chat message trigger runs a workflow when a message is received in MergePoint Chat. Use it to build conversational agents, assistants, or automated responders that activate when a user sends a message.
Setup
In the Start node inspector, select Chat message. Configure the options below.
Message Source
Choose which messages the trigger listens to:
- MergePoint — messages sent inside MergePoint Chat
- External — messages arriving from an external channel
- All — both sources
Agent Configuration
When this trigger is used to power a chat agent, configure the agent's identity:
- Agent name — the display name shown in the chat interface
- Agent description — a brief description of what the agent does
- Agent icon — an icon displayed next to the agent's name
Publicly available — when enabled, the chat agent can be accessed without logging in to MergePoint.
Hub enabled — when enabled, the agent appears in the MergePoint Chat hub.
Input Properties
Define structured input fields the agent can collect from users during the conversation. Each property has a name and type. These become available as step outputs in the workflow.
File Uploads
Allow file uploads — when enabled, users can attach files to their messages. Specify which MIME types are accepted (e.g. image/png, application/pdf).
Web Search
Allow web search — when enabled, the agent can perform web searches as part of its response.
Response Mode
Choose how the workflow sends its reply:
- Streaming — the response is streamed back to the user as it is generated, word by word
- Complete — the full response is sent once the workflow finishes
Filters
- Filter keywords — only trigger the workflow when the message contains specific words or phrases
- Ignore bots — skip messages sent by automated bots or other agents
Activation
The trigger only processes live messages after the workflow is published.
