Trying to set up Postman to send push notifications through AWS. I've got the notifications going out through the Test Notifications interface to a specific DeviceID in the management console. But I'm receiving the error message below when attempting to send via Postman.
{"message":"Credential should be scoped to correct service: 'mobiletargeting'. "}
Did you use the AWS Signature feature in the Authorization tab? If so, set the Service Name to mobiletargeting (that's an advanced setting of the authentication). Accept and Content-Type set to application/json
