How To Delete Slack Messages

by

Slack is a powerful communication tool that is widely used by teams across the globe. It helps to streamline communication, making it easy for team members to stay connected. However, there may be instances where you need to delete a message from a Slack channel. Whether you’ve posted something by mistake or the message is no longer relevant, knowing how to delete a Slack message can come in handy. Here is a step-by-step guide for doing just that.

Deleting a Slack Message

To delete a Slack message, follow the steps below:

  1. Open the Slack application on your device.
  2. Navigate to the channel where the message was posted.
  3. Hover over the message you want to delete. Several options will appear to the right of the message.
  4. Click on the three vertical dots (‘More actions’ icon).
  5. Click on the Delete message option. You will be asked to confirm your decision.
  6. Click on the Yes, delete this message button.

That’s it! Your message has been successfully deleted. Do note that only the author of the message or an admin can delete a message.

Deleting Multiple Slack Messages

If you want to delete multiple Slack messages at once, unfortunately, Slack does not provide a built-in feature for this task. However, there are third-party apps and scripts that can help. One such script uses the Slack API to delete messages.

Please note that using scripts or third-party apps should be done with caution. Always back up your data before using these methods.

Here’s an example of a script that uses the Slack API to delete messages. You will need to replace “token” and “channel” with your own information.

import requests

def delete_slack_messages(token, channel, ts_to):
    get_url = 'https://slack.com/api/conversations.history'
    delete_url = 'https://slack.com/api/chat.delete'
    headers = {
        'Authorization': f'Bearer {token}',
        'Content-type': 'application/json; charset=utf-8'
    }
    
    params = {
        'channel': channel,
        'latest': ts_to,
        'inclusive': True,
        'limit': 100
    }
    
    while True:
        r = requests.get(get_url, headers=headers, params=params)
        messages = r.json()['messages']
        
        for message in messages:
            delete_params = {
                'channel': channel,
                'ts': message['ts']
            }
            requests.post(delete_url, headers=headers, json=delete_params)
        
        if r.json()['has_more']:
            params['latest'] = messages[-1]['ts']
        else:
            break
delete_slack_messages(token="your-token", channel="your-channel", ts_to=timestamp)

Please replace “your-token” with your Slack API token, “your-channel” with the channel ID you want to delete messages from, and timestamp with the timestamp up to which you want to delete messages.

Remember to always be mindful of what you are deleting. Once a message is deleted on Slack, it cannot be recovered.

Conclusion

Knowing how to delete a Slack message can come in handy in many situations. While Slack doesn’t currently offer a built-in way to delete multiple messages simultaneously, scripts and third-party tools can fill in the gap when needed. Always proceed with caution when using these methods, backing up necessary data before proceeding with deletion.
