I have created a bot using Botkit and am working on creating an interactive message. What I want to do is when the user clicks on the button in the interactive message, a new message will be created pulling som info from the original interactive message, BUT WILL NOT BE SENT. I need to continue editing the message before choosing to send it. Does anybody know whether this is possible or not? I have been googling and searching slack's docs and botkit's docs, but haven't been able to find an answer.
If you want to let the user edit a message before sending you can use the Dialog feature from Slack. It will allow you to show an input text field, where the user can make his edits. I am not familiar with Botkit though and can not say if it supports Dialogs.

I want to show "show more" in slack messages.
I use the slack web api to send messages.
If the number of characters is long, I want to use the "show more" button.
What I've found so far is using the text field of secondary message attachments.
But since this is legacy, they tell me to use the block kit, but I don't know how.
(https://api.slack.com/reference/messaging/attachments)
Is there any way?
Using Block Kit, you aren't able to define where breaks/read more etc should occur. The theory is that you send the content as Blocks, and the Platform decides how best to render it for the device where it's viewed.
Instead of text fields you should send as attachments, then Slack should display a show more if there are too many attachments.
See more on https://api.slack.com/messaging/composing/layouts.
Note: Attachments is a legacy part of messaging functionality at Slack
My scenario is: I send card attachments each with an AcceptButton to users. When 1 user clicks on that button, ideally I want to disable all similar buttons (of the same offer) for all users. I am storing conversation details of each user, and I know the ActivityId of each message-with-said-button (it follows a certain string format).
My issue is similar to this and this but for WebChat not Teams.
I did try those solutions but I got the error "Method not allowed" for both UpdateActivityAsync() and DeleteActivityAsync(). Then I read here that UpdateActivity is not supported in WebChat. (But might be available in the future?)
I would like any visual indication that the offer is no longer available. (Right now, they receive an "Offer was already accepted by {UserX}" which would still be in place on top of changing the card/message.)
Is there a way to do this via backChannel? I can trigger an event and pass the ActivityId (tested by showing a simple alert()) but how do I apply changes to that specific activity?
Per this comment in Web Chat's source code and this open issue in the Web Chat repository for adding support for deleteActivity and updateActivity, Update Activity events are not currently supported in Web Chat. Unfortunately, there is currently no way to really update an activity in Web Chat.
Hope this helps!
In a Slack conversation, is it possible to click on a button to send a message to the Slack channel?
The Slack conversation could be:
The user types a word (or message)
A slackbot shows some text and two buttons
The user clicks on a button to send a TEXT message to the Slack channel
The Slackbot reacts on the 'action' message.
It is not possible to create an REST service for my Slackbot, because the Slackbot is behind a firewall. So, registering commands is not possible.
So sending a message as the result of a button click is needed. The Slackbot can react on that message.
I read that attachments could be a good way to do this, BUT the is 'outmoded'.
I tried to send an secondary attachment, which is outmoded, but that was not possible.
The next approach was adding a webhook. So pushing a button resulted in using the url, but that is of course not possible because I cannot send a POST request via a simple (get) url.
Please give a short example.
This will not work.
Every interactive feature (e.g. buttons) require your app to be able to receive POST requests from Slack through the public Internet. Since you say you can not provide that (e.g. behind a company firewall) you will not be able to use any interactive features.

Is there a way, by means of some setting or programmatically, to allow a user on Slack to confirm that the user really wants to send a message before the message is sent? Often times we end up sending messages on the wrong channels or DMs. How can we prevent these?
Assuming by "send a message" you mean "post a message" to a channel.
Via Settings
No. There is no Slack setting to enable confirmation before a message is posting.
Programmatically
No. Its possible to retrieve all messages that are posted to a channel with a Slack app (e.g. via Events API) and then react to them, but only after the fact. To the best of my knowledge it is not possible to insert some kind of confirmation logic into the standard process of posting a message.
I want my bot to post a message to a user which has a "delete" link to a particular message posted by that user. For e.g.
"Hi #someuser , you have posted an inappropriate message. Click >>here<< to delete it."
When the user clicks on "here" it will open up the slack delete message UI?
I have the message ts and channel ID.
I know i can do this via chat.delete api call (have the link point to my backend and then issue the chat.delete api call).
But i was wondering if there is a way to point user to the "delete message" window via a direct link in the message itself.
You can not add to or change the existing message of another user. Only delete a message (with admin rights).
What you can do though is send the guy a direct message from your app including the link (or button) to delete the message. Just send a message to the user ID of the user via chat.postMessage.
Or you can send the guy an ephemeral message into the channel, that only he will be able to see with chat.postEphermal.
To create a user experience similar to Slack's delete pop-up for messages I would suggest the following:
Include a "Delete" button in your message to the user with the
danger style, so it is shown in red color.
Include a confirmation pop-up with a copy of the message text.
