I need to send the multiple bot replies to the same channel. using this API method: https://api.slack.com/methods/chat.postMessage
But when i am sending multiple messages, The order in which the messages get rendered is not in the correct order, is there anyway to fix this.

I would like to send messages to users through Slackbot, just like integration apps such as Zapier.
If I set the channel ID to the user ID it sends a 1:1 message showing up in the Apps tab, but what I really would like to do is to send a message in Slackbot, as I want to create a seamless experience for a Workflow I'm creating.
Then, if I try adding the Slackbot channel ID it returns channel_not_found and there's no way to add the App there.
My current bot token scope to send messages is: chat:write and I'm sending a message using chat.postMessage
Do I need a different scope? Different API method? I've tried going through some other questions/answers, but they look outdated
I am building a slack application.
I added "incoming-webhook" to oauth scopes that let me choose the channel I want the App to post messages. However unless I ping the app in the channel to add it. I get a "channel not found" error.
Is it possible to add the app to a channel when installing app via oauth ? Without adding it manually by #app-name or /invite app-name ?
When you add an incoming-webhookscope to your app, the option to add a channel during authentication is specific to incoming webhooks not bot messages. So any messages you send via the incoming webhook will send to the channel you selected during authentication. Messages sent via [chat.postMessage][1] will require your bot to be a member of the destination channel, via invite. Incoming webhooks can only be linked to a single channel. You will have to create a new webhook for every channel you want to post to using webhooks. For that reason, I'd recommend using chat.postMessage instead. If you request the chat:write.public scope your bot will be able to post into any public channel without invitation.
I need to post multiple bot replies (responses determined dynamically) to the same channel.
The obvious way seems to be to do an HTTP POST for each message in succession using this API method: https://api.slack.com/methods/chat.postMessage
Is there a way to send messages to Slack in bulk to post to the same channel? The order in which the messages get rendered need not be important for me.
No, there is no bulk variant. So you basically need to build your own bulk message sender.
Keep in mind that there is a request limit of 1 message per second or your API requests will fail.
There also is a 3 seconds request time-out for many requests between Slack and your app. (e.g. for direct response to slash commands). So if your bot needs to send many messages you want to use an approach that allows you to send them asynchronously.
One solution to this problem that works very well for me is to use a messaging queue for all Slack messages sent from my bots.
You can try multiple messages as attachements -> https://api.slack.com/reference/messaging/attachments
I want my bot to respond only if anyone mentions its name like #mybot.
How to achieve this?
For that you need to use the Events API and subscribe to the event app_metion.
That way your app will receive all message that directly mention your bot with #mybot.
Those messages will be sent as request from Slack to the endpoint provided for receiving events.
