Q:

Message attribute names starting with 'AWS.' or 'Amazon.' are reserved for use by Amazon

I'm using nodejs. According to the documentation of AWS I should use the following sentence in order to change the senderid :
 MessageAttributes: {
'AWS.SNS.SMS.SENDERID': {
  'DataType': 'String',
  'StringValue': 'BLABLA'
}

When I'm running it, I get back this error:
ParameterValueInvalid: Message attribute names starting with 'AWS.' or 'Amazon.' are reserved for use by Amazon.

I believe that they have probably limited the access to use AWS after making the documentation, but I could not find another way to change the sellerid online.  Does anyone have a solution for this?

A:

The correct attribute name is AWS.SNS.SMS.SenderID but you're using AWS.SNS.SMS.SENDERID.
