Hey @shimaper,

What Slack documentation are you following?

Hi @Jon , this one: Incoming webhooks for Slack | Slack

Hey @shimaper,

In that case what you need is the HTTP Request node, You would need something like this…

But as that involves making a Slack app you could also just use the Slack node we have which might be easier.

Hello, I think this is post message, but I need to get new message from channel, I think I need something like trigger (webhook). Otherwise I can use cronjob and fetch all messages, but it is not common way to get new messages, right?

Hey @shimaper,

In that case the documentation you have been following is the wrong one, You will need the Slack Events API which you can find here: Using the Slack Events API | Slack
