Overview

This node integrates with the VKontakte (VK) social network API, specifically enabling sending messages when the Resource is set to Messages and the Operation is Send Message. It allows users to send text messages to a specified peer (user, chat, or community) on VK.

Common scenarios where this node is beneficial include:

  • Automating customer support by sending notifications or replies via VK messages.
  • Broadcasting updates or alerts to VK users or groups.
  • Integrating VK messaging into workflows for marketing campaigns or user engagement.

Example: Automatically send a welcome message to new users who sign up on your platform by triggering this node with their VK peer ID and a custom message.

Properties

Name Meaning
Count Number of items to return (used in various operations but not directly relevant here).
Offset Offset for pagination (used in various operations but not directly relevant here).
Message The text content of the message to be sent.

Additional required input parameters for sending a message (not listed in the provided properties but used internally):

  • peerId: The identifier of the recipient (user, chat, or community).

Output

The node outputs JSON data representing the response from the VK API after attempting to send the message. This typically includes information such as the message ID, status, or any error details if the operation failed.

No binary data output is involved in this operation.

Example output JSON snippet might look like:

{
  "message_id": 12345
}

or in case of error:

{
  "error": "Error message describing what went wrong"
}

Dependencies

  • Requires an API key credential for VKontakte OAuth2 authentication configured in n8n.
  • Depends on the VKontakte API being accessible at https://api.vk.com/method.
  • Uses an internal VKApi helper class to interact with VK endpoints.

Troubleshooting

  • Common issues:

    • Missing or invalid peer ID will cause the message sending to fail.
    • Insufficient permissions or expired API token can result in authorization errors.
    • Network connectivity problems may prevent reaching the VK API.

  • Common error messages:

    • "Unknown operation: sendMessage": Indicates a misconfiguration of the operation parameter.
    • API errors returned from VK, e.g., rate limits exceeded or invalid parameters.

  • Resolutions:

    • Ensure the peer ID is correctly provided.
    • Verify that the API credentials are valid and have the necessary scopes.
    • Check network connectivity and retry if transient errors occur.
    • Use the node's "Continue On Fail" option to handle errors gracefully in workflows.
