Wechat Official Account Node

Overview

This node interacts with the Wechat Official Account platform to retrieve data related to user tags. Specifically, for the "用户标签" (User Tag) resource and the "获取用户身上的标签列表" (Get User's Tag List) operation, it fetches the list of tags associated with a particular user identified by their OpenID.

Common scenarios where this node is useful include:

• Segmenting users based on their tags for targeted messaging or marketing campaigns.
• Managing user groups dynamically by fetching their current tag assignments.
• Integrating user tag information into CRM or analytics workflows.

For example, you might use this node to get all tags assigned to a user who just interacted with your service, then decide which promotional message to send them next.

Properties

Output

The node outputs JSON data representing the list of tags associated with the specified user. Each item in the output array corresponds to a tag object containing details such as tag ID and tag name (exact fields depend on the Wechat API response).

If the node supports binary data output, it is not indicated here; thus, the output is purely JSON-based.

Dependencies

• Requires an API key credential for authenticating with the Wechat Official Account platform.
• The node depends on internal helper modules for resource and operation management.
• No additional external services are explicitly required beyond the Wechat Official Account API access.

Troubleshooting

• Common issues:

  • Providing an invalid or empty OpenID will likely cause the operation to fail or return no tags.
  • Network or authentication errors if the API key credential is missing, expired, or incorrect.
  • If the specified resource-operation combination is not implemented, the node throws an error indicating the method is not implemented.

• Error messages:

  • "未实现方法: 用户标签.获取用户身上的标签列表" means the requested resource-operation is not implemented.
  • Errors during API calls will be logged with detailed messages and stack traces.
  • If "Continue On Fail" is enabled, errors for individual items will be returned as JSON objects with an error field instead of stopping execution.

To resolve these:

• Ensure the OpenID is valid and correctly passed.
• Verify that the API credentials are properly configured and have necessary permissions.
• Check network connectivity to the Wechat API endpoints.
• Enable "Continue On Fail" cautiously to handle partial failures gracefully.
