How to Create a Twilio Account for Linxi
Linxi runs on top of your own Twilio account — it never provisions numbers on your behalf. This guide covers creating the account and finding the two credentials Linxi actually needs from it.
Why you need Twilio at all
Twilio is the carrier-connectivity layer — it owns the actual phone number, sends/receives SMS to the cellular networks, and is who Twilio's Trust Hub and TCR (The Campaign Registry) hold responsible for A2P compliance. Linxi is the inbox, contacts, and campaign layer on top of it. You need both.
Create the account
Go to twilio.com and sign up with an email address and password (or Google sign-in). Twilio will ask what you're building — any answer is fine, it doesn't gate anything. New accounts start in trial mode with a small amount of free credit.
Navigating the new console (1console.twilio.com)
Twilio rolled out a redesigned console — everything now lives under a Products and services menu in the left sidebar, grouped by category (Communications, Messaging, etc.) instead of one long flat list. Account-level settings (SID, Auth Token, billing) moved under a separate Settings menu, also in the left sidebar.
Finding your Account SID
In the left sidebar: Settings → Account settings → API keys & auth tokens, then the Auth tokens tab. Your Account SID is shown at the top of that page.
AC is your Account SID, even though Twilio doesn't always label it clearly on that page — look for the 34-character string beginning with those two letters.
Finding your Auth Token
Same page as the Account SID (Settings → Account settings → API keys & auth tokens → Auth tokens tab). The Auth Token is hidden by default — click the eye icon next to "Primary auth token" to reveal it, then copy it. Treat it like a password: anyone with it has full control of your Twilio account, including the ability to send messages and spend your balance.
Trial vs. paid account
A trial account can only send SMS to phone numbers you've manually verified in the console, and every outbound message is prefixed with "Sent from your Twilio trial account." You'll need to add a payment method and upgrade before Linxi can send to real, unverified contacts.
