3.8 Twilio
Configure your Twilio account credentials for outbound phone calls. Once saved, these
credentials are shared across all your workflows — any Phone Call or AI Phone Call node
will use them automatically without per-step configuration.
Getting Your Twilio Credentials
-
Sign up or log in
Go to
twilio.com and
create a free account or log in to your existing account.
-
Open the Twilio Console
After logging in, navigate to the
Console Dashboard at
console.twilio.com. Your Account SID and
Auth Token are displayed on the dashboard home page under
Account Info.
-
Buy a phone number
Go to Phone Numbers → Manage → Buy a number in the Twilio
Console. Search for a number with Voice capability in your desired country. The number
will appear in your account once purchased and can be used as the From
Number in Flusso.
Trial accounts: Twilio trial accounts can only call verified phone numbers.
To place calls to arbitrary recipients, upgrade your Twilio account to a paid plan.
Configuration Fields
| Field |
Required |
Description |
| Account SID |
Required |
Your Twilio Account SID — a 34-character string beginning with AC.
Found on the Twilio Console Dashboard under Account Info. Stored encrypted.
|
| Auth Token |
Required |
Your Twilio Auth Token — used to authenticate API requests. Found alongside the
Account SID on the Console Dashboard. Treat this value as a password; it is stored
encrypted and never displayed after saving.
|
| From Number |
Required |
The Twilio phone number from which outbound calls will be placed. Must be in
E.164 format, e.g. +15550001234. The number must belong to your
Twilio account and have Voice capability enabled.
|
Saving Your Settings
-
Open Twilio settings
Navigate to Settings → Twilio in the sidebar.
-
Enter your credentials
Paste your Account SID, Auth Token, and From Number into the respective fields.
-
Test the connection
Click Test Connection to validate your credentials against the Twilio
API. Flusso checks that the Account SID and Auth Token are valid and that the From
Number exists on the account.
-
Save
Click Save. The credentials are stored encrypted and immediately
available to all workflow nodes that place phone calls.
Tip: Always use Test Connection before running a live
workflow. An invalid Auth Token or an unverified From Number will cause every Phone Call
node to fail at runtime.
Where These Credentials Are Used
The Twilio credentials configured here are shared across your entire Flusso account and
are automatically used by the following workflow nodes:
-
Phone Call — places an outbound call and reads a script or questionnaire
to the recipient using Twilio's text-to-speech synthesis.
-
AI Phone Call — places an outbound AI-driven call where the conversation
is handled by a language model. Supports ElevenLabs voices when an ElevenLabs API key is
also configured under Settings → ElevenLabs.
No per-node credentials: There is no credential field on individual Phone
Call or AI Phone Call nodes. The account-level Twilio settings here apply to all calls
placed by any workflow in your account.
