WeChat Enhanced

Overview

The "WeChat Enhanced" node provides comprehensive integration with various WeChat services, including Mini Programs, Official Accounts, WeChat Pay, and WeChat Work. Specifically, for the WeChat Work resource with the Get Media operation, this node allows users to retrieve media files stored in WeChat Work by specifying a Media ID.

This functionality is useful when automating workflows that require fetching images, videos, or other media assets uploaded or shared within WeChat Work. For example, a company might use this node to automatically download and process media files sent in corporate chats or stored in the enterprise account.

Properties

Output

• The output contains a JSON object representing the media file retrieved from WeChat Work.
• The exact structure depends on the media type and WeChat Work API response but generally includes metadata and the media content or a URL to access it.
• If the media is binary (e.g., image, video), the node typically returns the media data encoded or accessible via a link, suitable for further processing or saving.

Dependencies

• Requires an active subscription and valid API key credential for the external "N8N Tools API" service, which acts as a proxy or helper for WeChat API calls.
• Requires OAuth2 or API key credentials configured in n8n for authenticating with WeChat Work.
• The node internally uses a helper library (wechat-api) to interact with WeChat APIs.
• Proper permissions and access rights in the WeChat Work account are necessary to fetch media files.

Troubleshooting

• Invalid subscription or API key error:
  If you receive errors indicating invalid subscription or API key, verify that your API key credential for the external service is correct and active.

• Unsupported operation error:
  This node supports only predefined operations per resource. Ensure you select "Get Media" under the "WeChat Work" resource.

• Media not found or access denied:
  Check that the provided Media ID is correct and that the authenticated WeChat Work account has permission to access the media.

• Network or timeout issues:
  Ensure stable internet connectivity and that the external API endpoint is reachable.
