Sending SMS with Twilio API

Setup overview

• Create a Twilio account
• Get Account SID + Auth Token
• Buy/verify a sender phone number

Store secrets in env vars:

• TWILIO_ACCOUNT_SID
• TWILIO_AUTH_TOKEN

Example

twilio_sms.py

import os
 
# from twilio.rest import Client
 
 
def send_sms(to: str, body: str):
    account_sid = os.environ["TWILIO_ACCOUNT_SID"]
    auth_token = os.environ["TWILIO_AUTH_TOKEN"]
 
    # client = Client(account_sid, auth_token)
    # msg = client.messages.create(
    #     body=body,
    #     from_="+15551234567",
    #     to=to,
    # )
    # return msg.sid
 
 
# send_sms("+15550001111", "hello")

Notes

• keep rate limits in mind
• never hardcode auth tokens
