Just prepend docker run -it --rm sgratzl/slack-cleaner for each command does not work for me.
I only get slack-cleaner to work if I run it from inside the container shell.

i.e. use https://pypi.python.org/pypi/colorama

I only wanted to delete messages from one incoming webhook in a channel but the botname did not want to filter out those messages. I tired a few different variation but I always got 0 messages back.

I tried to filter the messages by the title or message but that did not seem to work too. I would like to delete the messages from "production Monolog" but keep those from "staging-server"

Hey there - I need some help.
I keep getting the following error:
AttributeError: 'dict' object has no attribute 'iteritems'

And here's the last bit from the console:

Any advice?

slack-cleaner: error: unrecognized arguments: --purge yes

Hi,

I'm once again trying to use slack-cleaner as my semestr starts. THis time I get a new error about the attributes of the Slacker object:

Hi.
I used this one for cleaning up my space from files and it works great, thanks! 🥇
I used it with a: https://github.com/auino/slack-downloader which is a simple script to download the files, but gets the job done as well.
I'm wondering if you think it would be desired to add a backup feature to this user-friendly toolkit of yours.

It appears that there isn't a way to delete direct messages where one or more of the users has a username with a space in it. One of my users has a "First Last" username. I've tried putting the name in quotes, as well as using the "@" code (ex: <@U2B7M4JKQ>). This @ code I tried with and without the opening and closing brackets, as well as with quotations.

e.g. SLACK_TOKEN

original idea from https://github.com/higanworks/slack-cleaner

I'm using 0.5 (just installed w/ pip) but am getting what seems like the behaviour described in #37:

slack-cleaner --token=XXXXXXXXXXXXXXXXX --channel tech-setup --message --as_user 
Running slack-cleaner v0.5.0
Deleting messages from channel tech-setup

0 message(s) will be cleaned.

I justregenerated the token so I think that is not the issue (though I am not sure how else to test that).

Thank you, let me know if I na help debug!

Hello,

Thank you very much for making this fork of slack-cleaner and maintaining it.

I'm trying to run slack-cleaner behind my company proxy which messes up SSL certificates to make them not valid. Is it possible to disable the SSL check as a flag or something?

Failed to delete (HTTPSConnectionPool(host='slack.com', port=443): Max retries exceeded with url: /api/chat.delete?token= (Caused by SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726)'),)))->

nevermind

Started cleaning slack recently from CI bot spam
Once I got over 100 messages I start receiving:
Failed to delete (429 Client Error: Too Many Requests for url: https://slack.com/api/chat.delete?token=<my token>

According to Slak's Documentation the error shows up once you reach the limit and you should start parsing Retry-After parameter in the response.

I am using --group and the name of the channel is correct as far as I can tell.

Are there some new Slack limitation on the channel containing more than X messages then can't delete with the API ?

Running slack-cleaner v0.3.0
Channel, direct message or private group not found

currently they are mixed up with commands and options.

possible structure

basic commands:

• message - delete messages
• bot - delete bot messages
• files - delete files
• info - dump information about users and channels

extras:

• invert the logic add ad --dry-run instead of --perform
• don't separate groups and channels but unify them

Hi,
i can delete normal message, but no webhook message.
i always get the error message:

platform:

1. mailclark website (https://help.mailclark.ai)
2. using docker with main branch of slack-cleaner
3. I am chat channel owner and granted API

e.g. a simple support for storing messages in some place before deleting them, such as

• a json file
• a mongodb
• stdout

Using --channel works, however, whenever I try to run the command with --group to delete all messages from a private channel it does not recognize the channel.

I'm trying to delete messages delivered to a channel via the Twitter or Google Calendar apps, but the slack-cleaner does not appear to detect these messages even in a public channel.

Hello! I'm running slack-cleaner v.0.4.0 on Python 3.6, via PowerShell. I'm trying to delete one particular bot's messages from one particular channel:

PS C:\1\insta_env> slack-cleaner --token xxxx --message --channel internal-updates --botname notion
Running slack-cleaner v0.4.0
Deleting messages from channel internal-updates

�[92m0�[0m message(s) will be cleaned.

Now you can re-run this program with `--perform` to actually perform the task.

I guess it's a character issue, but still, even after initiating the delete via --perform with this output,

�[92m0�[0m message(s) cleaned.

All the messages remain. None are deleted. Have I missed a crucial step here? This is the bot whom I'm trying to wipe.

Here's what the app looks like:

see https://api.slack.com/types/file

field: url_private_download

see also the authentication section: Authorization: Bearer A_VALID_TOKEN header is required

To enable the use of the botname parameter the below code will enable filtering based on an exact match of the username using the botname parameter when using the 'bot' message type option:

I'm the owner of the Slack workspace
and I'm trying to remove messages from Direct Messages.

It deleted my own messages without any issues.
But the other person's messages I can't delete.
Not a single one.

Getting (with --rate of 3) on every message:

Failed to delete (cant_delete_message)->

    u'text': u'XXX ',
    u'ts': u'XXX',

}

Any ideas?

always happy if someone goes on with a great idea.... thanks man !!!

for debugging purposes since the internal names aren't obvious all the time.

Around 90% of our Slack space is comprised of direct messages, and we're fast approaching the 10k nag. Can I delete DMs using wildcards?

I've tried:

slack-cleaner --rate $RATE --token $TOKEN --message --direct "*" --user "*" --before $DATED $1

With no luck.

Hello.
Whenever I --perform some query that is to delete tens of messages - I usually get 429 errors (about exceeding rate limit).
If I set --rate high enough to not get those errors - deleting goes too slow: even with rate of 0.7 I from time to time get those errors, so I'd rather go at rate 0.1 and delete things faster but also get more 429 errors.

Anyways, my question is about the exit status: shouldn't it be non-zero in case there was at least a single message not deleted due to an error?
I think it makes sense to set exit status equal the number of failed attempts to delete a message.

Or there should be an option to just move the failed tasks to the end of queue?

After deleting files, these messages appear in the channel history. These messages cannot be found by slack-cleaner to delete.

Hi,
let me kindly announce official packages available in the Fedora repository, currently for Rawhide, F30 and EPEL7 (latter as addon for RHEL7/CentOS7). I'm the proud maintainer of both packages named slack-cleaner and python-slacker (as dependency).
Commands to install:

# Fedora
dnf install slack-cleaner
# EPEL7
yum install -y epel-release ; yum install slack-cleaner

Regards.

Everything works really well, except that when deleting all messages on a channel, I find that the replies on a thread are usually left behind. I've tried most of the args to try getting rid of it but am hitting a wall.

Hello.
I can't delete any message from logs channel.
I run : slack-cleaner --token TOKEN --message --channel CHANNEL --bot --perform --rate 5.
Scopes under this token :

users:read
channels:history
channels:read
chat:write:user
chat:write:bot

Running the cleaner on my machine with a fresh install is appearing to have problems finding any files to delete. This is a new problem, I have successfully run it in the past with no problems. Not getting any error messages, just the below output:

slack-cleaner --token <token> --file --user "*" --rate=5
Running slack-cleaner v0.4.1
Deleting all matching files

0 file(s) will be cleaned.

Also pulled the latest Docker image and tried that method, to no avail.

docker run -it --rm sgratzl/slack-cleaner -c "slack-cleaner --token <token> --file --user \"*\""
Running slack-cleaner v0.4.1

Now you can re-run this program with `--perform` to actually perform the task.

Also reissued a new token and tried that with no success.

Hey there!

Been looking for a python program to bulk delete messages from Slack, and stumbled upon this project. Anyway, I pulled the image from Docker and ran slack-cleaner with the following arguments:
/backup # slack-cleaner --token TOKEN --message --channel test --user "*"

This got thrown back at me:

Any ideas?

Is your feature request related to a problem? Please describe.
I want to run your script on a cron, so I would like to issue the same command every day. For example:

slack-cleaner --channel debug --bot --perform --before 'yesterday'

To remove all messages older than a day. Right now I have to calculate the date it was yesterday using some other library or tool.

Describe the solution you'd like
I would like the --before and the --after parameters to take human readable input as well as YYYYMMDD

Describe alternatives you've considered
Wrapping your tool in ruby, since it's pretty easy to work with dates in Ruby

Additional context
I'm a lazy sysadmin and would 100% understand that you can't/won't implement this feature. Btw: amazing product, please keep it alive!

I do slack-cleaner --token <MY_TOKEN> --info and I get a list of users, public channels, private channels, instant messages and multi user direct messages, which proves my token is working.

Then I do slack-cleaner --token <MY_TOKEN> --message -channel <ANY_CHANNEL> and it says that 0 message(s) will be cleaned, but we do have messages in the channel! And I have enough rights to remove messages at least from myself and from bots.

This happened first with slack-cleaner v0.3.0 (although it worked before), then I updated to v0.4.0 and the issue is still there.

When I’m trying to get info on the group, I get this error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xf1' in position 28: ordinal not in range(128)

Rather than having the user guess what the rate should be, it would be ideal if the application handles gracefully 429's errors Client Error: Too Many Requests.

When using the --keeppinned argument, I am seeing an unrecognized argument error. If I remove this argument, everything runs well. Was this option removed or renamed recently?

Launch Command:
slack-cleaner --token TOKEN --message --keeppinned --channel test --user "*" --perform --rate 1

Console Output:
usage: slack-cleaner [-h] --token TOKEN [--log] [--rate RATE] (--message | --file) [--channel CHANNEL | --direct DIRECT | --group GROUP | --mpdirect MPDIRECT] [--user USER] [--bot] [--after AFTER] [--before BEFORE] [--types TYPES] [--perform] slack-cleaner: error: unrecognized arguments: --keeppinned

Per the Readme, this should be right:
usage: slack-cleaner [-h] --token TOKEN [--log] [--quiet] [--rate RATE] [--as_user] [--message | --file] [--regex] [--channel CHANNEL] [--direct DIRECT] [--group GROUP] [--mpdirect MPDIRECT] [--user USER] [--botname BOTNAME] [--bot] **[--keeppinned]** [--after AFTER] [--before BEFORE] [--types TYPES] [--pattern PATTERN] [--perform]

Im sure that there are more messages in channel but it only deletes messages that are available in Slack itself. what can be done?

I orginally tried to delete all files for everyone older than July 1st, e.g.:
slack-cleaner --token xxx --file --user "*" --before 20170701
It says 391 will be deleted, try again with --perform. I do it again:
slack-cleaner --token xxx --file --user "*" --before 20170701 --perform
and it errors on all 391 it looks like, with the following for each:
Failed to delete (delete() got an unexpected keyword argument 'as_user') ->

I restricted it to myself:
slack-cleaner --token xxx --file --user "kelly" --perform
which should have deleted a handful of files and I get the same error.
Running slack-cleaner v0.4.0
Deleting all matching files
Failed to delete (delete() got an unexpected keyword argument 'as_user') ->
(etc)

Ideas?

I had an existing token I tried to with slack-cleaner; it failed with a cryptic invalid_scope error. Eventually I found documentation that certain APIs only work with user tokens (ones that start wtih xoxp and not bot tokens xoxb).

A quick note on the documentation might save others some trouble.
