Send messages → Send meeting event
AI-generatedOverview
This node allows sending a WhatsApp meeting event message via the WaliChat WhatsApp API. It is designed to create and send calendar-like event invitations directly into WhatsApp chats, groups, or channels. This is useful for scheduling meetings, appointments, or reminders with rich event details such as name, description, date/time, location, and call type.
Practical scenarios include:
- Sending meeting invites to clients or team members through WhatsApp.
- Broadcasting event notifications to WhatsApp groups or channels.
- Automating appointment reminders with event details and optional location coordinates.
- Including voice or video call options linked to the event.

Output
The node outputs JSON data representing the result of the send meeting event operation. This typically includes confirmation details such as message IDs, status, timestamps, or error information if the operation failed.
No binary data output is expected from this operation.
Dependencies
- Requires an active WaliChat WhatsApp API connection authenticated via an API key credential configured in n8n.
- The node depends on WaliChat backend services to send WhatsApp messages and manage chats.
- Some properties load dynamic options (e.g., devices, groups, channels, agents, labels) which require proper API access and permissions.
Troubleshooting
- Invalid phone number format: Ensure phone numbers follow the E.164 format (e.g., +1234567890). Errors will occur if the regex validation fails.
- Missing required fields: Event name, date/time, and target identifiers (phone/group/channel) are mandatory. Omitting these will cause errors.
- Delivery failures: Using real-time delivery mode ("live" or "never queue") with high message volume may lead to WhatsApp bans or throttling.
- Incorrect quoting: Quoting a message ID not in the same conversation will fail.
- Agent or department IDs: Must be valid 24-character hexadecimal strings; invalid IDs will cause validation errors.
- Message expiration misconfiguration: Ensure expiration times are within allowed ranges and correctly formatted.
- Strict order conflicts: Using strict message order with incompatible delivery modes will cause errors.
To resolve issues, verify all inputs against their validation rules, check API credentials, and consult WaliChat API documentation for rate limits and usage policies.
