Using MessageAttributes in AWS SNS Post request

Question

I am trying to use the MessageAttributes parameter in AWS SNS POST request. This is to customize the Sender ID (by AWS.SNS.SMS.SenderID). I am trying for Germany phone number and hence is allowed to customize the Sender ID. Can any one help me with the correct syntax?

Thanks, Subhajit

You need to send 3 key/value pairs for each attribute:

MessageAttributes.entry.${index}.Name=${attributeName}&
MessageAttributes.entry.${index}.Value.DataType=String&
MessageAttributes.entry.${index}.Value.StringValue=${attributeValue}

${index} is the numerical index of each attribute, starting with 1

On the second line you need to specify the type of the value. Most common cases are String.

The third line is the actual value. You can see more information in the link above, I have only used strings and StringValue.

All the values need to be url-encoded for obvious reasons.
