Overview
This node interacts with the WhatsApp API to mark a specific chat as unread. It is useful in scenarios where you want to programmatically flag conversations for follow-up or attention, such as in customer support workflows or automated messaging systems. For example, after processing messages from a chat, you might mark it unread to remind agents to review it later.
Properties
| Name | Meaning |
|---|---|
| Id | The unique identifier of the WhatsApp instance to target. |
| Chat Id | The identifier of the chat to mark as unread. Format: <countrycode_short><usernumber>@c.us for individual chats or @g.us for groups. |
Output
The node outputs JSON data representing the result of the "mark chat unread" operation. This typically includes confirmation of the action or any relevant status information returned by the WhatsApp API. There is no binary data output.
Dependencies
- Requires an active connection to the WhatsApp API service.
- Needs an API key credential configured in n8n to authenticate requests.
- The base URL for the API is
https://waapi.app/api/v1. - The node uses standard HTTP headers for JSON content.
Troubleshooting
- Invalid Chat Id format: Ensure the chat ID follows the correct pattern (
<countrycode><number>@c.usfor individuals or@g.usfor groups). - Authentication errors: Verify that the API key credential is correctly set up and has necessary permissions.
- Network issues: Confirm that the n8n instance can reach the WhatsApp API endpoint.
- API rate limits: If too many requests are sent in a short time, the API may reject calls; implement retries or backoff strategies.
