Overview

This node operation locks a poll on the Zalo platform by its poll ID. It is useful for scenarios where a poll needs to be closed or locked to prevent further voting or changes. For example, after a poll has reached its deadline or sufficient responses, this operation can be used to lock the poll to finalize results.

Use Case Examples

1. Lock a poll by providing its poll ID to prevent further votes.
2. Use in automated workflows to close polls at a scheduled time.

Properties

Output

JSON

• success - Indicates if the poll was successfully locked (boolean).
• response - The response data from the Zalo API after locking the poll.
• poll_id - The ID of the poll that was locked.

Dependencies

• Requires Zalo API credentials (cookie, imei, userAgent) to authenticate and perform the lock operation.

Troubleshooting

• Ensure the poll ID is valid and exists on the Zalo platform.
• Verify that the Zalo API credentials are correctly configured and have not expired.
• Common error: 'No API instance found' indicates missing or invalid credentials; re-authenticate to resolve.
• If the poll cannot be locked, check if it is already locked or if the user has permission to lock it.
