I was wondering if there was a way to post messages on Slack without using a bot, directly from a user’s account. I don’t seem to find a way to do that and bots are not always the most suitable (or possible) option, specially in workspaces where you can’t approve the bot. It feels strange because n…

As a random user in the channel or as you?

I would guess that he wants to send it on behalf of someone else on the team? Because you can send a message as you. Unless I’m missing something.

As myself. For now, all sending options are through a bot (Token or OAuth authentication alike) and that requires having permissions to install bots in each workspace. You can send block messages via the Block Kit page and that goes as oneself (can select all workspaces and then the destination ch…

I did wonder if that was the case but it wouldn’t be very good if someone could randomly send a message as another user. Doesn’t it need each user to go through the Auth process so the user can grant the permission for the app to send?

Correct, you should only be able to send messages from accounts that you control; and that’s the intention here. The point is to not need an app to send the message, rather to do it directly on behalf of your own user (which as mentioned above is possible via Slack API and can be tested with the Bl…

Perhaps using incoming web-hooks? [image] Sending messages using Incoming Webhooks Creating an Incoming Webhook gives you a unique URL to which you send a JSON payload with the message text and some options.

That solution seems to still need to have app permissions for each workspace. I can’t wrap my head around the fact that Slack wouldn’t allow to authenticate a connection as a user and then let you post via API.

Maybe the trick is that it can only be done via Web API? [image] Using the Slack Web API The Web API is an RPC-style collection of methods that either yield information about Slack workspaces or allows your app to enact change within them. Learn how to formulate requests it will underst…

You still need a token for that one which need and admin to create but would do the job. Same deal with a web hook, I think the main problem might be with how slack works. User accounts are treated as unique between workspaces whereas with say Discord you have one user account and use that to join …

While user accounts are treated as unique, the Blocks Kit Builder allows for the objective to be accomplished, seamlessly. Unless Slack has some kind of Super-Admin access over all the workspaces and can internally assign a token then I don’t see how it is not possible to reproduce the same behavior…
