How this works

This workflow enables businesses to automate customer support on WhatsApp by routing incoming messages to the most suitable agent based on predefined criteria, ensuring faster and more personalised responses. It's ideal for small teams or solo entrepreneurs handling high volumes of queries without constant manual oversight, saving hours of triage time each day. The key step involves parsing the incoming message via a webhook, validating it, checking for opt-outs or group blocks, then querying Airtable to find and assign the optimal agent before merging their details for seamless handoff.

Use this when you need efficient message distribution in a WhatsApp-based support setup with structured agent data in Airtable, particularly for text-only interactions. Avoid it for voice or media-heavy communications, or if your team requires real-time collaboration tools beyond basic routing. Common variations include adding HTTP requests for external API checks, like sentiment analysis, or integrating error triggers to log and retry failed assignments.
