Slack Bolt - can not receive dm msg

[kohei-miyata]

Channels where the created application exists can retrieve messages. However, some users can retrieve messages in DMs, while others cannot.

The application does not invite in DM.

I don't see any problem

with authority, etc. Because some users can get them. Do we need anything else?

import os
from slack_bolt import App
from slack_bolt.adapter.socket_mode import SocketModeHandler
from dotenv import load_dotenv

load_dotenv() 
app = App(token=os.environ.get("SLACK_TOKEN"))
domain = 'XXXX'
send_channel = 'DDDDD'
@app.event("message")
def handle_direct_mention(event, client):
    channel_type = event.get("channel_type")
    print(json.dumps(event, indent=2, ensure_ascii=False, sort_keys=True))
    text = event.get("text", "")
    user = event.get("user", "")
    channel = event.get("channel")
    ts = event.get("ts")
    channel_type = event.get("channel_type")
    thread_ts = event.get("thread_ts") if event.get("thread_ts") else None
    url = get_message_url(domain, channel, ts)
    if thread_ts:
        url += f"?thread_ts={thread_ts}"
    category = talk = "スレッド" if thread_ts else "チャンネル"
    url = f"<{url}|メッセージを確認する>"
    #print(url)
    #print(channiel)
    mention_user_ids = ['AAAA', 'BBBBB', 'CCCC']

    if any(f'@{user_id}' in text for user_id in mention_user_ids) and channel != send_channel:
        if channel_type == 'group':
            type = 'チャンネル'
        elif channel_type == 'im':
            type = 'DM'
        else:
            type = '不明'
        dt_now = datetime.datetime.now()
        user_info = client.users_info(user=user)
        username = user_info['user']['profile']['display_name'] or user_info['user']['real_name']

        print("\n--- debug in U030YMK1X61 ---")
        print(f"現在日時{dt_now}")
        print(json.dumps(event, indent=2, ensure_ascii=False, sort_keys=True))
        converted_text = emoji.emojize(text, language='alias') 
        client.chat_postMessage(

        )

def get_message_url(domain, channel_id, ts):
    ts_formatted = ts.replace(".", "")
    return f"https://{domain}.slack.com/archives/{channel_id}/p{ts_formatted}"

Hi there!

If I understand correctly, this relates to the app receiving message events when users post in certain channels; message events are received as expected for regular channels where the app bot has been added as a member, but the app does not receive message events for messages posted in direct message (private) channels? This would be the expected behaviour as an app cannot listen to messages in a channel where the bot user doesn't have membership

[kohei-miyata]

Yes, your understanding is correct.

However, we have observed that some users are able to receive message events from direct messages, even though the app was not explicitly added to the DM and has never interacted in the conversation.

Do you know why this might be happening?

If possible, we would like to be able to receive messages from all direct messages. Is there a way to achieve this?

some users are able to receive message events from direct messages, even though the app was not explicitly added to the DM and has never interacted in the conversation.

Oh! You're right! With the message.im User Event subscription, you should be able to receive message events from DMs where at least one of the users have 'authorized' the app. It's the message.im Bot Event subscription where the bot user must be part of the conversation in order to receive events.

Assuming your app is subscribed to the User Event and the app was reinstalled after adding the subscription, it sounds like the issue would be that in some DMs one or both participants may not have installed the app
