Bulk Import Subscription to AWS SNS Topic

AWS SNS currently does not have a bulk import option for adding subscriptions.

Please remember AWS SNS API throttling Limits before implementing this.

The possible workaround is as follows:

Prerequisites

1. awscli
2. Access and Secret Keys
3. terminal

Create a file company.txt and the endpoints for example lets say you want to subscribe phone numbers of your employees in the company.

$ company.txt
+11111111111
+11111111112
+12222222222
+12222222221

2. Open a terminal and run the following command by replacing the topic-arn with your topic ARN.

while read line; do aws sns subscribe — topic-arn <TOPIC_ARN> — protocol sms — notification-endpoint $line; done < company.txt

PowerShell:
ForEach ($file in (Get-Content -Path company.txt
)) {aws sns subscribe — topic-arn <TOPIC_ARN> — protocol sms — notification-endpoint $file}

Then you can check it in the AWS SNS Console. You will see the subscription registered.
