Describe the problem/error/question

Hi all, I have multiple Bedrock Agents that I built that I want to connect to a Slack bot and call them via slash commands. How can I do that?

Hey, you need to figure out two main parts: how to route Slack commands to n8n and how to call your agents on Bedrock.

Slack setup

  • You need to create a Slack app and configure it to send slash command data to an n8n webhook
  • Go to Slack API: Applications | Slack and sign in
  • Click on “Create an App” => “From scratch”
  • Go to Slash Commands under the “Features” sections
    • “Create New Command”
    • Request URL: this should be a webhook in a new n8n workflow that you create
  • Under “Settings” click on “Install App”
    • you may need to get approval to install it in your workspace
  • Now in Slack go to a channel where you want to test the slash commands
    • in the field to write a message type “/invite” and select “Add apps to this channel”
    • select your newly created Slack app
    • now you should be able to use the slash commands in the channel, but you will likely get an error - to fully test this go to your n8n workflow with the webhook and click on “Listen for test event”
    • now the slash command should start the workflow

Call Bedrock

  • as of now there’s no existing node to call Bedrock agents from n8n, so you need to use the REST API
  • go to your n8n workflow and after the webhook node add a HTTP Request node
  • I’m not very familiar with Bedrock, but I think this is the API endpoint to call an agent: InvokeAgent - Amazon Bedrock
  • the API seems quite complicated to use, so you could also consider to implement your agents directly in n8n - it’s super easy and powerful! You can still use models from Bedrock in the Agent node

Once you have the basic setup running you can improve things, like adding a Switch node in n8n to distinguish which Slack slash command was sent (you can figure it out by the payload that the webhook receives from Slack).
