Dependencies
- Requires an active WeChat Official Account with appropriate permissions to send customer messages.
- Needs an API authentication token or key configured in n8n credentials to authorize requests to the WeChat API.
- The base URL defaults to
https://api.weixin.qq.com/cgi-bin/but can be overridden via credentials.
Troubleshooting
- Invalid or expired media IDs: If the video media ID or thumbnail media ID is incorrect or expired, the API will return an error. Ensure that media files are uploaded and valid before referencing their IDs.
- User OpenID issues: Sending to an invalid or unsubscribed user OpenID will fail. Verify the recipient’s OpenID is correct and that they have interacted with the Official Account.
- API authentication errors: Missing or incorrect API credentials will cause authorization failures. Confirm that the API key/token is correctly set up in n8n.
- Message size limits: Videos exceeding WeChat’s size or duration limits may be rejected. Check WeChat documentation for media constraints.
