RCS Setup with Twilio

This guide explains how to create an RCS Sender in Twilio and share access with Alvio.

Before you start

• A paid Twilio account (console.twilio.com (opens in a new tab))
• Brand assets: logo, banner, privacy policy URL, and terms of service URL
• Carrier approval can take several weeks — start early if you have a launch date

1. Create an RCS Sender

1. Log in to the Twilio Console (opens in a new tab).
2. In the left menu, open Numbers & senders > Overview.
3. Open the RCS tab.
4. Click Create new sender.

5. Enter your display name (the brand name users will see), accept the terms, and continue.
6. Fill in the brand profile Twilio asks for (description, logo, banner, accent color, contact details, privacy policy, and terms of service).
7. Save the sender. You can add a test device later if you want to try messages before approval.

2. Submit for carrier approval

1. Open your RCS Sender → Compliance registration.
2. Select the countries where you want RCS.
3. Complete the registration form (business details, opt-in / opt-out, use case).
4. Submit and wait until at least one carrier shows as Active for your region.

3. Add the sender to a Messaging Service

Alvio sends through a Twilio Messaging Service, so the RCS Sender must be in its sender pool.

1. Go to Messaging > Services and create a service (or open an existing one for Alvio).
2. Add your RCS Sender to the Sender Pool.
3. (Recommended) Also add an SMS number for fallback when RCS is unavailable.
4. Copy the Messaging Service SID (MG…).

4. Give Alvio access

Use one of the options below once the sender is approved and in a Messaging Service.

Option A — Share credentials securely

Send these values to Alvio via a secure channel (password manager share, encrypted note — not plain email if possible):

The Auth Token grants full API access. Prefer a dedicated Twilio subaccount for Alvio / RCS when possible.

Option B — Invite Alvio as Console admin

1. Ask your Alvio contact for the email to invite.
2. Go to Account > Manage users (or Organization settings > User management).
3. Invite that email with the Administrator role on the account that owns the RCS Sender.
4. Tell your Alvio contact once the invite is accepted.

With admin access, Alvio can complete the integration without you copying secrets.

Summary

1. Create the RCS Sender in Twilio.
2. Submit compliance registration and wait for approval.
3. Add it to a Messaging Service.
4. Share credentials or invite Alvio as admin.

Alvio handles the rest.
