Programmable SMS Python Quickstart
Ahoy there! All messaging transmitted using Twilio’s messaging channels is treated as Application-to-Person (A2P) messaging and subject to Twilio’s Messaging Policy. For detailed information on policy rules to ensure you remain compliant while using Twilio’s services, please see our Acceptable Use Policy.
With just a few lines of code, your Python application can send SMS messages with Twilio Programmable Messaging.
This Programmable Messaging Quickstart will walk you through the entire process step-by-step, starting with setting up your Twilio account all the way through sending an SMS using a Messaging Service.
このクイックスタートでは、下記のことを学んでいきます:
- Twilioにサインアップして、SMS機能を持ったはじめてのTwilio電話番号を入手する
- Set up your development environment to send outbound messages
- Send your first outbound SMS
- Set up your first Twilio Messaging Service
- Send a second SMS from that Messaging Service
By the end of this Quickstart, you’ll have a solid foundation for building and scaling with Twilio’s Programmable Messaging for your specific use cases.
Sign up for - or sign in to - Twilio
Already have a Twilio account? Go ahead and skip this section.
You can sign up for a free Twilio trial account here.
- When you sign up, you'll be asked to verify your personal phone number. This helps Twilio verify your identity and also allows you to send test messages to your phone from your Twilio account while in trial mode.
- Once you verify your number, you'll be asked a series of questions to customize your experience.
- Once you finish the onboarding flow, you'll arrive at your project dashboard in the Twilio Console. This is where you'll be able to access your Account SID, authentication token, find a Twilio phone number, and more.
Install the Twilio CLI
We'll use the Twilio CLI (command line interface) for a few tasks, so let's install that next.
The suggested way to install twilio-cli on macOS is to use Homebrew. If you don’t already have it installed, visit the Homebrew site for installation instructions and then return here.
Once you have installed Homebrew, run the following command to install twilio-cli:
brew tap twilio/brew && brew install twilioThe suggested way to install twilio-cli is by using Scoop, a command-line installer for Windows. If you don’t already have it installed, visit the Scoop site for installation instructions and then return here.
Note PowerShell will need to be run as an administrator to avoid common permission issues when installing via Scoop.
- Add the
twilio-cliBucket:
scoop bucket add twilio-scoop https://github.com/twilio/scoop-twilio-cli - Install the app:
scoop install twilio
twilio-cli can be installed using the Advanced Package Tool (apt) on most distributions such as Debian, Ubuntu, and Mint.
To do so, run the following commands in your terminal:
wget -qO- https://twilio-cli-prod.s3.amazonaws.com/twilio_pub.asc \
| sudo apt-key add -
sudo touch /etc/apt/sources.list.d/twilio.list
echo 'deb https://twilio-cli-prod.s3.amazonaws.com/apt/ /' \
| sudo tee /etc/apt/sources.list.d/twilio.list
sudo apt update
sudo apt install -y twilioFor other installation methods, see the Twilio CLI Quickstart.
Run twilio login to get the Twilio CLI connected to your account. Visit https://www.twilio.com/console, and you’ll find your unique Account SID and Auth Token to provide to the CLI.

Get a phone number
If you don't currently own a Twilio phone number with SMS functionality, you'll need to purchase one. With the CLI, run:
twilio phone-numbers:buy:local --country-code US --sms-enabledReplace US with your ISO-3166-1 country code if you would like a phone number in another country. If you aren't finding any SMS enabled numbers, try looking for a mobile number instead of a local number: twilio phone-numbers:buy:mobile --country-code DE --sms-enabled
Select a phone number to add it to your account.
Next, we need to install Python and the Twilio Python Helper Library.
PythonとTwilioヘルパーライブラリーをインストールする
すでに他のPythonクイックスタートを終えていて、PythonおよびTwilio Pythonヘルパーライブラリーがインストールされている場合は、このステップを読み飛ばしてすぐに最初のテキストメッセージを送信できます。
To send your first SMS, you’ll need to have Python and the Twilio Python helper library installed.
Pythonをインストールする
あなたがMacやLinuxマシン上にある場合、あなたはおそらくすでにPythonがインストールされています。 ターミナルを開いて下記のコマンドを入力することでこれを確認できます:
python --version下記のように表示されます:
$ python --version
Python 3.6Windows users can follow this excellent tutorial for installing Python on Windows, or follow the instructions from Python's documentation.
Twilio’s Python server-side SDK supports both Python 2 and Python 3. You can use either version for this quickstart, but we recommend using Python 3 for future projects with Twilio unless there are specific libraries your project needs which are only compatible with Python 2.
Please note: Twilio's Python 7.x library only supports Python 3.6+.
Install the Twilio Python Server-side SDK
The easiest way to install the library is using pip, a package manager for Python that makes it easier to install the libraries you need. Simply run this in the terminal:
pip install twilioIf you get a pip: command not found error, you can also use easy_install by running this in your terminal:
easy_install twilioIf you'd prefer a manual installation, you can download the source code (ZIP) for twilio-python and then install the library by running:
python setup.py installin the folder containing the twilio-python server-side SDK library code.
PythonでSMSを送信する
これでNode.jsとTwilio Pythonライブラリーがインストールできたので、今しがた購入したTwilio電話番号から、1回のAPIリクエストでSMSを送信できます。 send_sms.pyという名前のファイルを作成して開き、下記のコードサンプルを入力またはペースとします。
You’ll need to edit your send_sms.py file a little more before your message will send:
プレースホルダーのクレデンシャル値を置き換える
Swap the placeholder values for account_sid and auth_token with your personal Twilio credentials. Go to https://www.twilio.com/console and log in. On this page, you’ll find your unique Account SID and Auth Token, which you’ll need any time you send messages through the Twilio Client like this. You can reveal your auth token by clicking on the 'view' link:
send_sms.pyを開き、account_sidおよびauth_tokenに対応する値をご使用のアカウントの一意な値に置き換えます。
ご注意ください: 初めのうちは認証情報をハードコーディングしても構いませんが、本番環境にデプロイするにあたっては、環境変数を使用してこれらが漏洩しないようにしてください。 追加情報については、環境変数の設定方法を参照してください。
from 電話番号を置き換える
Remember that SMS-enabled phone number you bought just a few minutes ago? Go ahead and replace the existing from_ number with that one, making sure to use E.164 formatting:
[+][country code][phone number including area code]
to 電話番号を置き換える
Replace the to phone number with your mobile phone number. This can be any phone number that can receive text messages, but it’s a good idea to test with your own phone so you can see the magic happen! As above, you should use E.164 formatting for this value.
トライアルアカウントをご使用の場合、Twilioで検証済みの電話番号に送信先が制限されます。電話番号はTwilioコンソール内の検証済み発信者番号にて検証できます。
When you send an SMS from your free trial phone number, it will always begin with "Sent from a Twilio trial account." We remove this message after you upgrade.
変更を保存し、ターミナルからこのスクリプトを実行します:
python send_sms.py一丁上がり！ ほどなくして、Twilio電話番号から携帯電話にSMSが受信されるはずです。
米国かカナダに顧客がいますか？ もう1行コードを追加すれば、そのお客様にMMSも送信可能です。 方法を確認するには、MMS送信のガイドを参照してください。
In this code sample, we are making a POST request to the Programmable Messaging API’s Message endpoint in order to create a new outbound message. We are using the twilio-python library’s built-in create method, but you could make this request using the Twilio CLI (that you already installed), curl, or a request module of your choosing.
Check out the code samples to send an SMS with the Twilio CLI and curl. Don't forget to update the body, to, and from parameters!
Set up a Twilio Messaging Service
Congratulations, you’ve sent your first SMS with Twilio Programmable Messaging and received it on your personal device.
At this point, we have acquired one Twilio phone number and used it to send one outbound SMS. You can imagine a time in the not-so-distant future where you'll need a more robust, feature-rich way to send messages, such as:
- sending many messages over a short period of time
- handling opt-ins and opt-outs
- ensuring that your customers always receive a consistent messaging experience with the same phone number.
In the next part of the Quickstart, we’ll walk through setting up your first Messaging Service. You can think of a Messaging Service as a container to hold all of your available phone numbers (and other senders) and comes with features that you may need along your messaging journey.
Create a Messaging Service with your phone number
Run the following Twilio CLI command to create a Messaging Service that we will use to send our first programmable SMS.
twilio api:messaging:v1:services:create --friendly-name "My first Messaging Service"Take note of the Messaging Service SID (It starts with “MGXXX...”). We'll need it to send our next message.
Next, add the phone number you just purchased. Forgot the number already? No worries, you can list it with the Twilio CLI:
twilio phone-numbers:list
# Grab the SID ("PNXXXX...") of your numberAdd your phone number to your newly created Messaging Service with the following command:
twilio api:messaging:v1:services:phone-numbers:create --service-sid MGXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX --phone-number-sid PNXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Send an SMS from your Messaging Service
Sending an outbound SMS from a Messaging Service is similar to sending from an individual Twilio phone number. The primary difference is replacing the from_ parameter with the messaging_service_sid to indicate that you are sending from a phone number within your Messaging Service’s sender pool. (Currently, there is only one phone number in your sender pool, so we'll be sending from that one.)
Replace the messaging_service_sid parameter
Remember that Messaging Service you just created? Instead of the from_ parameter and your phone number, use the messaging_service_sid parameter with the "MGXXXX..." of your Messaging Service SID. Save your changes and run this script from your terminal:
python send_sms.pyAnd that’s in to send an SMS using a Twilio Messaging Service! In a few seconds, you should receive a second SMS on your phone from your Twilio phone number. The Messaging Service seamlessly selected your number from its Sender Pool to send that second outbound message.
