AWS SNS how to add line breaks in message

Question

I\'m trying to send SNS messages via CLI in json format.

aws sns publish --cli-input-json \"{\\\"TopicArn\\\":\\\"xxx\\\",\\\"Message\\\":\\\"first line\\n          


        

Answer 1

I think \\n is actually what you are looking for. I've just tested it by sending push notifications to my device through AWS SNS.

So your message should look like this:

aws sns publish --cli-input-json "{\"TopicArn\":\"xxx\",\"Message\":\"first line\\nsecond line\",\"Subject\":\"Empty subject\"}"

Note, you should not leave the white space after the line break symbol, otherwise, your new line would start with that space.
