Example script to Send SMS via AWS SNS using boto

Here's the code to publish directly to a phone number via SNS using boto3. If you get an error regarding the PhoneNumber parameter, you'll need to upgrade your version boto. It's important to remember that SNS currently supports direct publish to a phone number (PhoneNumber) or push notifications endpoint (targetArn). Also note that TopicArn, PhoneNumber, and TargetArn are all mutually exclusive and therefore you can only specify one of these per publish.

import boto3

sns_client = boto3.client('sns')

response = sns_client.publish(
    PhoneNumber='+12065551212', 
    Message='This is a test SMS message',
    #TopicArn='string', (Optional - can't be used with PhoneNumer)
    #TargetArn='string', (Optional - can't be used with PhoneNumer)
    #Subject='string', (Optional - not used with PhoneNumer)
    #MessageStructure='string' (Optional)
)

print(response)

The below script is working for me just replace the required parameters that are defined as constants in the script. The below script also handles bulk SMS to multiple recipients

import json
import boto3
import os


ACCESS_KEY = <your key>
ACCESS_SECRET = <your secret>
AWS_REGION = <your region>

RECIPIENT_NUMBERS = [<recipient number list>]
SENDER_ID = <sender_id>
MESSAGE = <your message>

sns = boto3.client('sns', aws_access_key_id=ACCESS_KEY,
               aws_secret_access_key=ACCESS_SECRET,
               region_name=AWS_REGION)
for number in RECIPIENT_NUMBERS:
    response = sns.publish(
        PhoneNumber=number,
        Message=MESSAGE,
        MessageAttributes={
            'AWS.SNS.SMS.SenderID': {'DataType': 'String',
                                 'StringValue': SENDER_ID},
            'AWS.SNS.SMS.SMSType': {'DataType': 'String',
                                'StringValue': 'Promotional'}
        }
    )
    print(response)

Just replace in required fields, you will get this working.

import boto3
# Create an SNS client
client = boto3.client(
    "sns",
    aws_access_key_id="your_access_key_id",
    aws_secret_access_key="you_secret_access_key",
    region_name="us-east-1"
)

# Send your sms message.
client.publish(
    PhoneNumber="your_phone_number",
    Message="Hello World!"
)
