Overview
This node facilitates the OAuth authentication flow for VK (VKontakte), a popular Russian social media platform. It helps users obtain an authorization URL to start the OAuth process, which is necessary to get access tokens for interacting with VK APIs on behalf of a user.
Common scenarios where this node is useful include:
- Integrating VK login or data access into custom workflows.
- Automating VK API calls that require user authorization.
- Managing VK OAuth flows in n8n without manually constructing URLs.
For example, a user can generate the authorization URL, open it in a browser to grant permissions, and then use the obtained authorization code in subsequent steps to fetch access tokens.
Properties
| Name | Meaning |
|---|---|
| Client ID | The Client ID obtained from your VK application, identifying your app during OAuth flow. |
| Client Secret | The Client Secret obtained from your VK application, used to securely authenticate. |
| Redirect URI | The callback URL where VK will redirect after authorization; must match your app settings. |
| Scope | Permissions requested from the user, e.g., email, wall, offline. |
| Manual Mode | Whether you want to manually open the authorization URL and paste the authorization code. |
Output
The node outputs a JSON array with one object containing the following fields:
authUrl: The generated VK OAuth authorization URL to be opened by the user.clientId: The provided Client ID.clientSecret: The provided Client Secret.redirectUri: The provided Redirect URI.scope: The requested permission scopes.manualMode: Boolean indicating if manual mode is enabled.note(optional): A message prompting the user to open the URL in their browser when manual mode is disabled.
This output serves as the starting point for the OAuth flow, providing all necessary information to proceed with user authorization.
Dependencies
- No external libraries are required beyond standard HTTP/URL encoding.
- Requires valid VK application credentials (Client ID and Client Secret).
- The Redirect URI must be registered in the VK application settings.
- The node expects the user to handle the next steps of the OAuth flow (e.g., exchanging authorization code for tokens) outside this node.
Troubleshooting
- Invalid Client ID or Secret: Ensure the credentials are correctly copied from your VK developer console.
- Redirect URI mismatch: The Redirect URI used here must exactly match the one registered in your VK app settings.
- Scope issues: Requesting invalid or unauthorized scopes may cause VK to reject the authorization request.
- Manual Mode confusion: If manual mode is enabled, you must manually open the URL and paste the authorization code elsewhere; forgetting this step will halt the flow.
- Authorization URL not working: Verify URL encoding and parameters; ensure network connectivity and VK service availability.
