Wechat Official Account Node

Actions43

Overview

This node interacts with the Wechat Official Account platform, specifically to retrieve permanent media materials. It is useful when you need to fetch stored media files such as images, videos, or other content that has been permanently saved on the Wechat server. For example, a marketing automation workflow might use this node to pull a specific image or video by its media ID to include in outgoing messages or posts.

Properties

Name Meaning
媒体文件ID The unique identifier of the permanent media file to retrieve from the Wechat server.

Output

The node outputs JSON data representing the retrieved permanent media material. This typically includes metadata and content details about the media file identified by the provided media ID. If the media contains binary data (e.g., an image or video), it will be included in the output's binary property for further processing or download.

Dependencies

  • Requires an API key credential for authenticating with the Wechat Official Account platform.
  • The node depends on the Wechat Official Account API being accessible and the media ID being valid and existing on the server.

Troubleshooting

  • Common issues:

    • Invalid or expired media file ID: The node will fail if the media ID does not exist or has been deleted.
    • Authentication errors: Ensure the API key credential is correctly configured and has sufficient permissions.
    • Network or API downtime: Temporary failures may occur if the Wechat API is unreachable.

  • Error messages:

    • "未实现方法: 素材.获取永久素材" ("Unimplemented method: Resource.Operation") — indicates the requested resource-operation combination is not supported; verify correct resource and operation names.
    • Errors containing "errorMessage" in the output JSON indicate specific API or execution errors; check the message for details.
