Is there a SNS function that lists all endpointARNs?

Question

Is there a SNS function that can be called inside a Lambda function to retrieve all SNS endpointARNs? Better yet, can it filter endpointARN by the "user data" attribute?

Answer 1

The closest you'll get is the listEndpointsByPlatformApplication method of the SNS client in the AWS SDK for Node.js.

Example usage (from the linked documentation):

var params = {
  PlatformApplicationArn: 'STRING_VALUE', /* required */
  NextToken: 'STRING_VALUE'
};
sns.listEndpointsByPlatformApplication(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Notes:

• This API is paginated; every response will contain a max of 100 results and return with a NextToken value that you need to pass into subsequent requests to get the next batch. The last page will return a null value for NextToken.
• The data object in the callback will contain a map<String> called Attributes that you can parse to filter for only endpoints having the CustomUserData attribute.
