Trello to Twilio SMS Lead Alerts via n8n Webhook

Turn new Trello lead cards into instant Twilio SMS alerts—safely

This n8n workflow listens for new or updated Trello cards, extracts lead details (including a phone number), and sends an SMS via Twilio to confirm or alert your team. It also includes a preview/safe mode that builds the message without sending it—so you can verify content before going live.

What this workflow does

• Receives webhook input: it handles a POST request from a Trello webhook when a card is created/updated, or you can run a demo that injects sample Trello card payloads.
• Loads centralized configuration: pulls Trello/Twilio settings, lead label rules, and a configurable SMS template, then processes the incoming card payload.
• Parses lead details from the Trello card: extracts fields such as contact name, phone, email, company, budget, timeline, labels, and the Trello card URL.
• Filters non-qualified cards: rejects cards missing a required phone number or the required lead label, returning a rejection reason without attempting to send.
• Renders the SMS: generates the message body from the configured template and selects the recipient number (the card phone number, or an optional test number in preview mode).
• Sends via Twilio (optional): if Twilio is enabled and DRY_RUN is off, it sends the SMS using the Twilio Messages API and returns success or the failure reason.
• Preview mode: if Twilio is not enabled, it outputs an exact SMS preview (to/from/body) so you can validate the content safely.

Use cases

• Instantly notify leads or internal staff when a new lead card is added to Trello.
• Prevent accidental SMS sends by validating templates and lead data in preview mode.
• Automate lead routing based on Trello labels (only qualified cards trigger SMS).

Technical details

• Webhook trigger for incoming Trello events
• HTTP Request / API calls as needed for Trello/Twilio interactions
• if node for qualification logic (label/phone checks)
• code node for parsing and message rendering
• no op and sticky note for workflow structure and clarity

Set your Trello webhook to call the workflow’s production webhook URL, provide Trello and Twilio credentials, and deploy a reliable Trello to Twilio SMS lead alert automation in n8n.
