You can build a variety of bots in Slack using Zapier, including reply bots that respond to specific phrases, notification bots that watch for notifications from other apps and send them to Slack, and slash command bots that wait for commands and then perform actions. Reply bots are the easiest to make, while slash command bots are the most advanced. Notification bots can save your team time by automatically sending updates to Slack. To build a reply bot, you can use Slackbot responses or create a custom bot using Zapier. For notification bots, you can connect an app like Trello or Google Calendar and have Zapier send notifications to Slack. To build a slash command bot, you need to add a new app to your Slack account, select the Slash Commands button, and then configure the command with a request URL that points to a Zapier webhook. You can then use Formatter, searches, and standard Zapier actions to gather data from other apps and send it back to Slack. Additionally, you can build bots for other team chat apps like Discord, Microsoft Teams, or Google Chat using Zapier's notification bot feature.
