2. Locate the Account Info section on the Dashboard
3. Note the following information: - Account SID: Format ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx - Auth Token: Click to reveal and copy (keep this secure)

2. Select a country and check the SMS capability
3. Choose and purchase a number (trial accounts get one free number)
4. Note your Twilio phone number (format: +1xxxxxxxxxx)

Number Selection Tips: - Choose a number from the same country as recipients to reduce costs - For international recipients, consider the destination country's regulations - Some countries require sender ID registration

Step 4: Configure Environment Variables¶

Add Twilio parameters to your backend_api_python/.env file:

# =========================
# Phone / SMS Configuration (Twilio)
# =========================

# Twilio Account SID (required)

# Twilio Sender Number (required)
# Format: +CountryCodeNumber, e.g., +14155552671
TWILIO_FROM_NUMBER=+14155552671

Restart the backend service after configuration to apply changes.
