You have successfully integrated WhatsApp with Slack for customer support using Vonage's AI Studio low-code platform. You built a custom solution that allows agents to respond directly from Slack, and enables customers to send continuous messages back and forth between their phone's WhatsApp and Slack. The integration uses low-code development tools to create a seamless experience for both humans and machines. With this setup, you can now test sending message replies from Slack and receive them on the WhatsApp side. You also created slash commands for ending conversations, which allows AI Studio to know when to stop the conversation and exit the Live Agent Routing node. This integration is perfect for startups and small businesses that lack resources for full-fledged customer support solutions.
