Overview
The node provides enhanced integration with WeChat services, supporting multiple resources including Official Account, Mini Program, WeChat Pay, and WeChat Work. Specifically for the Official Account resource with the Upload Media operation, the node allows users to upload various types of media files (such as images, voice, video, thumbnails, or generic files) to their WeChat Official Account.
This functionality is beneficial when you want to programmatically manage media assets on your Official Account, for example:
- Uploading images or videos to be used in messages or posts.
- Adding voice clips or other media types for interactive content.
- Managing media files without manual intervention through the WeChat API.
Practical example: A marketing automation workflow could use this node to upload promotional images or videos to the Official Account, which can then be sent to subscribers via message campaigns.
Properties
| Name | Meaning |
|---|---|
| Media Type | The type of media being uploaded. Options: Image, Voice, Video, Thumb, File |
| Media | The media file data encoded in base64 format. This is the actual content to upload |
Output
The output JSON contains the response from the WeChat Official Account API after uploading the media. Typically, this includes metadata about the uploaded media such as a media ID that can be used in subsequent operations (e.g., sending messages referencing the uploaded media).
If the node supports binary data output for media, it would represent the uploaded media file or related binary content; however, in this case, the media is input as base64 and the output is JSON metadata only.
Dependencies
- Requires an active subscription and valid API key for the external "N8N Tools API" service, which acts as a proxy/validation layer for WeChat API calls.
- Requires credentials for authenticating with the WeChat API (via OAuth2 or API keys).
- The node internally uses a helper class (
WeChatApi) to interact with the WeChat Official Account API endpoints. - Proper configuration of these credentials and API keys within n8n is necessary for successful execution.
Troubleshooting
- Invalid subscription or API key error: If the node throws errors indicating invalid subscription or API key, verify that the API key credential is correctly configured and active.
- Unsupported operation error: Ensure the selected operation matches the supported ones for the Official Account resource; "uploadMedia" must be chosen explicitly.
- Base64 encoding issues: The media property must be a valid base64 string representing the media file. Invalid or corrupted base64 data will cause upload failures.
- API rate limits or permissions: The WeChat API may impose rate limits or require specific permissions for media uploads. Check your WeChat Official Account settings and API quotas.
- Error messages from WeChat API: These are passed through and should be inspected for details like unsupported media types, size limits, or authentication failures.
