Slack + Webhooks by Zapier + Google Vertex AI

Start new conversations with a Google Vertex AI assistant from caught webhooks and post the replies in a Slack channel

Using this Zap template, you can build a Google Vertex AI slash command bot that lets you converse with a Google Vertex AI assistant (and get answers about your company files) right inside Slack. When setting up your command in Slack, use your Webhook URL to connect your Slack app to Zapier. Then, you'll be able to send a prompt to Google Vertex AI using the slash command, and carry on the conversation in a Slack thread.
