Clio Matter Status Webhook to Client Email via SMTP (n8n)

Clio Matter Status updates delivered to clients by email—only when the status truly changes (n8n)

This n8n workflow listens for Clio matter status webhooks, verifies and fetches the latest matter and firm user details via the Clio API, and then sends a compliance-checked status update email to the client using SMTP—but only when a new status should be delivered (no duplicates, no first-seen noise). It also keeps your Clio webhook subscription renewed on a daily schedule.

What this workflow does

• Handles Clio webhook events: completes the one-time X-Hook-Secret verification handshake or acknowledges the event.
• Validates payloads: checks the webhook contains a matter ID and skips unrelated or malformed events.
• Pulls authoritative data from Clio: fetches current matter details and firm user information to determine client email, responsible attorney, and current status.
• Sends only real status changes: compares the new status against the last recorded status in workflow static data and skips if it’s the first time seen or a duplicate delivery.
• Builds the email from firm-written messaging: uses a status-specific message for the new status, creates a personalized email, and runs a separate compliance/opt-out guardrail workflow.
• Sends via SMTP (plain-text + HTML): delivers to the client only if approved; otherwise it skips sending (including opt-out scenarios).
• Renews webhook subscription daily: lists existing Clio webhook subscriptions and creates/renews when missing, unconfirmed, or nearing expiration.

Use cases

• Automatically notify clients when their Clio matter status changes—without manual outreach.
• Reduce email spam by suppressing duplicate and first-time notifications.
• Ensure messages comply with client communication rules using an opt-out guardrail before SMTP delivery.
