Overview
This node interacts with the Wechat Official Account platform, specifically allowing management of user blacklists. The "取消拉黑用户" (Unblacklist Users) operation under the "用户" (User) resource enables removing one or more users from the blacklist by specifying their OpenIDs. This is useful in scenarios where previously blocked users need to regain access or interaction capabilities with the official account.
Practical examples include:
- Reinstating users who were mistakenly blacklisted.
- Allowing previously blocked users to receive messages or interact again after resolving issues.
- Batch unblocking up to 20 users at once for efficient management.
Properties
| Name | Meaning |
|---|---|
| OpenID列表 | A list of OpenIDs representing users to be removed from the blacklist. Up to 20 OpenIDs can be provided per execution. Each OpenID uniquely identifies a user on the Wechat platform. |
The property structure expects multiple values, each containing an "Openid" string identifying a user.
Output
The node outputs JSON data representing the result of the unblacklisting operation for each input item. Each output item corresponds to an input and contains either the success response or an error message if the operation failed for that item.
No binary data output is indicated.
Dependencies
- Requires valid API authentication credentials for the Wechat Official Account platform.
- The node depends on internal helper modules for resource and operation management.
- Proper configuration of the Wechat Official Account API credentials within n8n is necessary.
Troubleshooting
Common Issues:
- Providing more than 20 OpenIDs in a single request will likely cause errors due to API limits.
- Invalid or expired API credentials will prevent successful calls.
- Incorrect OpenIDs (nonexistent or malformed) may cause partial failures.
Error Messages:
- Errors thrown during the call are captured and can be returned per item if "Continue On Fail" is enabled.
- Typical error messages relate to invalid parameters, authentication failures, or API rate limits.
Resolutions:
- Ensure the OpenID list does not exceed 20 entries.
- Verify API credentials are current and have sufficient permissions.
- Validate OpenID formats before submission.
- Use "Continue On Fail" cautiously to handle partial failures gracefully.
