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, the node supports multiple operations such as sending messages, managing users and departments, uploading media, and retrieving media files.

The Get Media operation under the WeChat Work resource allows users to retrieve media files stored in WeChat Work by specifying a Media ID. This is useful when you need to access images, videos, or other media uploaded to WeChat Work for further processing, archiving, or sharing within your workflows.

Practical examples:

• Automatically download and process images sent to a WeChat Work group.
• Retrieve video recordings shared via WeChat Work for analysis or storage.
• Access documents or other media files uploaded by employees or clients through WeChat Work.

Properties

Output

The output of the Get Media operation contains a JSON object representing the retrieved media file's data. The exact structure depends on the media type and the underlying 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 will provide the media content appropriately encoded or referenced so that subsequent nodes can handle it (e.g., save to disk, upload elsewhere).

Dependencies

• Requires an active connection to the WeChat Work API, authenticated via appropriate credentials (such as an API key or OAuth2 token).
• Uses an external service called "N8N Tools API" for subscription and API key validation before executing operations.
• The node expects valid credentials configured in n8n to authenticate requests to WeChat Work.
• No additional environment variables are explicitly required beyond standard credential setup.

Troubleshooting

• Invalid subscription or API key error: If the node throws an error indicating invalid subscription or API key, verify that the API key credential used is correct and has the necessary permissions.
• Unsupported operation error: Ensure that the selected operation matches the resource; for example, "Get Media" must be used with the WeChat Work resource.
• Media not found or invalid Media ID: Confirm that the Media ID provided exists and is accessible with the current credentials.
• Network or API errors: Check network connectivity and WeChat Work API status if requests fail unexpectedly.
• JSON parsing errors: When providing JSON input parameters (not applicable for Get Media), ensure the JSON is well-formed.
