Status Codes

Status Code	Description
200	Users removed from blacklist successfully
400	Request parameter error
403	No management permission
404	Channel does not exist
500	Internal server error

Functionality

Remove Operation

The remove operation performs the following steps:

1. Verify Users: Check if specified users are in the blacklist
2. Remove Entries: Delete specified users from channel blacklist
3. Restore Permissions: Users regain ability to send and receive messages
4. Restore Conversations: Restore user’s related conversations if applicable

Permission Restoration

Removed users will regain:

Permission	Description	Effective Time
Send Messages	Can send messages to the channel	Immediately
Receive Messages	Can receive channel messages	Immediately
Conversation Access	Restore channel conversations (if applicable)	Immediately
Normal Interaction	Restore all normal channel interaction permissions	Immediately

Special Cases

Live Channels

• No Conversation Restoration: Live channels do not automatically restore conversations
• Permissions Take Effect Immediately: Users can still immediately regain send and receive permissions

Person Channels

• Blacklist Not Supported: Person channels do not support blacklist operations
• Returns Error: Attempting operations will return corresponding error messages

Use Cases

Lift Mistaken Ban

# Remove users mistakenly added to blacklist
curl -X POST "/channel/blacklist_remove" -d '{
  "channel_id": "group123",
  "channel_type": 2,
  "uids": ["innocent_user"]
}'

Batch Restoration

# Batch remove multiple users
curl -X POST "/channel/blacklist_remove" -d '{
  "channel_id": "group123",
  "channel_type": 2,
  "uids": ["user1", "user2", "user3"]
}'

Temporary Unban

# Temporarily lift user restrictions
curl -X POST "/channel/blacklist_remove" -d '{
  "channel_id": "group123",
  "channel_type": 2,
  "uids": ["temp_banned_user"]
}'

Best Practices

1. Permission Verification: Ensure operator has sufficient management permissions
2. Operation Recording: Record all blacklist change operations
3. Notification Mechanism: Notify relevant administrators and users
4. Progressive Unbanning: For serious violators, consider progressive permission restoration
5. Monitoring Mechanism: Continue monitoring user behavior after removal
6. Backup Strategy: Backup current blacklist state before bulk operations

Error Handling

Common Errors

Error Message	Cause	Solution
Channel ID cannot be empty	No channel ID provided	Ensure valid channel ID is provided
Channel type cannot be 0	Invalid channel type	Use valid channel type (1 or 2)
uids cannot be empty	No user list provided	Provide list of user IDs to remove
