Overview

This node allows sending message status updates (such as typing indicators) to a Zalo chat thread, either with an individual user or a group. It is useful in scenarios where you want to programmatically indicate that a user or bot is typing or update the message status in a conversation on the Zalo platform.

Practical examples include:

  • Showing a "typing..." indicator in a Zalo chat while your bot processes a response.
  • Sending custom message status updates to inform users about ongoing actions.
  • Integrating Zalo messaging status updates into automated workflows for customer support or marketing.

Properties

Name Meaning
Thread ID The unique identifier of the Zalo chat thread where the message status will be sent.
Type The type of the message recipient: either a single User (0) or a Group (1).

Output

The node outputs JSON data with the following structure:

  • success: Boolean indicating if the operation was successful.
  • message: A simple confirmation string "OK" when sending status updates succeeds.
  • In case of errors, error contains the error message.
  • Additional fields may include details about the thread and message content depending on the exact operation.

No binary data output is produced by this node.

Dependencies

  • Requires an API key credential for authenticating with the Zalo platform.
  • Uses the zca-js library internally to interact with Zalo's API.
  • Needs proper configuration of credentials within n8n to function correctly.

Troubleshooting

  • Common issues:

    • Failure to initialize the Zalo API usually indicates invalid or missing credentials.
    • Errors sending typing events might occur if the thread ID or type is incorrect.
    • Network or permission issues can cause message sending failures.

  • Error messages:

    • "Failed to initialize Zalo API. Check your credentials." — Verify that the API key and other authentication details are correct.
    • "Error sending Zalo message: <details>" — Indicates a problem during the send operation; check thread ID, message type, and network connectivity.
    • If the node throws errors referencing inability to send typing events, ensure the thread exists and the bot/user has permission to send status updates.
