Overview

This node integrates with the Zalo Poll service, allowing users to manage polls within the Zalo platform. Specifically, it supports operations such as creating a new poll, retrieving detailed information about an existing poll, and locking a poll to prevent further votes.

A common use case is automating poll management in group chats or communities on Zalo, for example:

  • Creating a poll with specific questions and options.
  • Fetching poll results or details programmatically.
  • Locking a poll once voting is closed.

The operation "Lấy thông tin bình chọn" (Get poll information) retrieves detailed data about a poll by its ID, which can be useful for reporting or decision-making workflows.

Properties

Name Meaning
ID bình chọn (poll_id) The numeric ID of the poll to retrieve information for. This is required to identify which poll's details to fetch.

Output

The node outputs an array of items, each containing a json object with the following structure when performing the "getPoll" operation:

  • success: A boolean indicating if the API call was successful.
  • response: The detailed poll data returned from the Zalo API. This includes all relevant poll information such as question, options, votes, status, etc.
  • poll_id: The ID of the poll that was queried.

No binary data output is produced by this operation.

Dependencies

  • Requires valid Zalo API credentials including authentication cookies, device IMEI, and user agent strings.
  • Uses the external zca-js library to interact with the Zalo API.
  • The node expects these credentials to be configured in n8n beforehand.
  • Proper network access to Zalo's API endpoints is necessary.

Troubleshooting

  • Common issues:

    • Invalid or expired credentials may cause authentication failures.
    • Missing or incorrect poll ID will result in errors or empty responses.
    • Network connectivity problems can prevent API calls from succeeding.

  • Error messages:

    • "No API instance found. Please make sure to provide valid credentials."
      Means the node could not initialize the Zalo API client due to missing or invalid credentials. Verify credential setup.
    • Errors related to poll ID or parameters usually indicate missing or malformed input. Ensure the poll ID is provided and is a valid number.
    • If the node throws errors during execution but "Continue On Fail" is enabled, it will output error messages per item instead of stopping the workflow.
