Overview

Twilio is a communications platform for programmatic SMS, voice, WhatsApp, verification, and phone-number lookup. The Automize Twilio connector covers the message/call lifecycle, contact verification (OTP), and number metadata.

Regions: Twilio operates regional APIs (US1, IE1, AU1, SG1, BR1). Account SIDs are global but resources can be scoped to a region. Connector talks to api.twilio.com (auto-routes by account location).
Plans: Twilio is pay-as-you-go. All accounts have API access. SMS deliverability + cost vary by destination country and number type.

Setting up the connection

Auth type: HTTP Basic.

Sign in to console.twilio.com → Account → API keys & tokens.
Copy your Account SID and Auth Token (or create an API Key for granular scoping).
In Automize, open Settings → Connectors → Twilio → Add connection. Use Account SID as username, Auth Token as password.

Find your credentials at https://console.twilio.com/.

Rate limits

Twilio enforces ~1 message/sec on free trial, ~10/sec on paid. Higher via support ticket. Voice calls have lower per-second limits. The connector retries 429 with exponential backoff. For high-volume SMS, use Messaging Services (pooled numbers) rather than a single From number.

Data model

Phone-centric:

    Account (SID) ─┬─ Phone Numbers (your purchased numbers)
                   ├─ Messages (SMS + MMS + WhatsApp)
                   ├─ Calls (voice)
                   ├─ Verifications (OTP service)
                   └─ Recordings

FAQ

Why does my SMS to a country fail?: Country-specific rules – some need pre-registration (US A2P 10DLC, India DLT), specific number types, or content approval. Check Twilio's country guidelines.
Status callback – how?: Pass status_callback URL on Send SMS – Twilio POSTs status changes (sent → delivered/failed) to your webhook. Configure separately in Automize webhooks.
Trial account limitations?: Trial accounts can only send to verified phone numbers + have 'Sent from Twilio trial account' prepended to every SMS. Upgrade to a paid account to remove.
WhatsApp template – when?: Outside of a 24h business-initiated conversation window, you must use a pre-approved template. Within the 24h window after the user messages you, freeform replies are allowed.
