Let’s create a Slack bot that would tell you the current crypto value using Cloud Functions, which is a serverless way to deploy your function and run code on the cloud.

A. Create a bot in a new Slack Workspace

Step 1: Create or Sign in to Slack

Create/Sign in to a different slack workspace where we will create our bot and choose a workspace name for it.

You’re signed in to a new workspace now!

Step 4: Enable event subscription

On the left, go to the event subscriptions and enable events.

Now select all events we want to subscribe to from Subscribe to Bot Events. The event subscription will ensure slack sends the events when they occur to the link provided.
