Wechat Official Account Node

Actions43

Overview

This node integrates with the Wechat Official Account platform, specifically allowing users to modify existing draft messages. It is useful for scenarios where you need to update content in a previously saved draft before publishing or further editing. For example, if you have a multi-article draft and want to change one article's content without recreating the entire draft, this node enables that precise update.

Properties

Name Meaning
草稿ID The unique identifier (media_id) of the draft you want to modify.
要更新的文章在图文消息中的位置 The position index of the article within the multi-article draft to update (starting at 0). Only relevant for drafts containing multiple articles.
草稿对象(Articles)内容 The new content of the draft article(s) in JSON format. This should follow the structure defined by the Wechat Official Account API for updating drafts.

Output

The node outputs an array of JSON objects representing the result of the draft update operation. Each output item corresponds to an input item processed. If the update is successful, the output JSON will typically contain confirmation data from the Wechat API. In case of failure, the output JSON will include an error field describing the issue encountered.

No binary data output is produced by this node.

Dependencies

  • Requires an active connection to the Wechat Official Account API.
  • Needs an API authentication token or key configured in n8n credentials to authorize requests.
  • The node depends on internal helper modules for resource and operation management but no external libraries beyond those bundled with n8n.

Troubleshooting

  • Common Issues:

    • Invalid or missing media_id: Ensure the draft ID provided exists and is correct.
    • Incorrect index value: The index must correspond to an existing article position within the draft; otherwise, the update will fail.
    • Malformed JSON in the articles property: The JSON must conform to the expected schema as per Wechat's documentation.
    • Authentication errors: Verify that the API credentials are valid and have sufficient permissions.

  • Error Messages:

    • "未实现方法: draft.update": Indicates the requested operation is not implemented; check that the resource and operation names are correct.
    • API error responses will be passed through in the error field of the output JSON. Review these messages for specific issues like rate limits or invalid parameters.
