Get Channel_id through channel_name besides using conversations.list

[Tang20031010]

(Describe your issue and goal here)

Reproducible in:

The slack_bolt version

slack-bolt==1.18.1
slack_sdk==3.27.2

Python runtime version

Python 3.12.3

OS info

ProductName: macOS
ProductVersion: 14.4.1

Steps to reproduce:

I am trying to get channel id by channel name. I would like to let the user input a channel's name and use that to get the channel's id since I need the channel id to do conversations.join. I have found one thread in slackapi/bolt-js#1725 and tried the suggestion by using conversations.list to filter and then use the conversations.info. However, there are too many channels in the organization. I have tried pagination but still failed to retrieve all channels through conversations.list. I think there are more than 50000 channels and the return from conversations.list is not stable. Since that post is in 2023, I am wondering if we have additional solutions to this situation. The worst case I am thinking is letting user input the channel id.

Could you use the Block Kit Conversation Select Menu? It will render a drop down menu of conversations (channels, public or private, even DMs and MPDMs) that is contextual to the user (meaning: the user has access to them). Then, you can listen to block_actions payloads on this element to get channel / conversation ID.

Thank you for your quick response! I looked into it; however, this does not seem quite fit to my situation as what I want is to let the user only interact with the UI I implemented instead of going to slack to do the operation.

I see. Yes, it's a common request and unfortunately we have no good answer. If you have access to an admin token, you could use the admin.conversations.search API as it accepts a query parameter for the channel name. The other is to paginate through conversations.list, as you pointed out.

Thank you! I probably need to go with letting the user input channel_id.
