## Request Parameters
<a name="API_SetPlatformApplicationAttributes_RequestParameters"></a>

 For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

 **Attributes** Attributes.entry.N.key (key)Attributes.entry.N.value (value)  
A map of the platform application attributes. Attributes in this map include the following:  
+  `PlatformCredential` – The credential received from the notification service.
  + For ADM, `PlatformCredential`is client secret.
  + For Apple Services using certificate credentials, `PlatformCredential` is private key.
  + For Apple Services using token credentials, `PlatformCredential` is signing key.
  + For GCM (Firebase Cloud Messaging) using key credentials, there is no `PlatformPrincipal`. The `PlatformCredential` is `API key`.
  + For GCM (Firebase Cloud Messaging) using token credentials, there is no `PlatformPrincipal`. The `PlatformCredential` is a JSON formatted private key file. When using the AWS CLI, the file must be in string format and special characters must be ignored. To format the file correctly, Amazon SNS recommends using the following command: `SERVICE_JSON=`jq @json <<< cat service.json``.
+  `PlatformPrincipal` – The principal received from the notification service.
  + For ADM, `PlatformPrincipal`is client id.
  + For Apple Services using certificate credentials, `PlatformPrincipal` is SSL certificate.
  + For Apple Services using token credentials, `PlatformPrincipal` is signing key ID.
  + For GCM (Firebase Cloud Messaging), there is no `PlatformPrincipal`. 
+  `EventEndpointCreated` – Topic ARN to which `EndpointCreated` event notifications are sent.
+  `EventEndpointDeleted` – Topic ARN to which `EndpointDeleted` event notifications are sent.
+  `EventEndpointUpdated` – Topic ARN to which `EndpointUpdate` event notifications are sent.
+  `EventDeliveryFailure` – Topic ARN to which `DeliveryFailure` event notifications are sent upon Direct Publish delivery failure (permanent) to one of the application's endpoints.
+  `SuccessFeedbackRoleArn` – IAM role ARN used to give Amazon SNS write access to use CloudWatch Logs on your behalf.
+  `FailureFeedbackRoleArn` – IAM role ARN used to give Amazon SNS write access to use CloudWatch Logs on your behalf.
+  `SuccessFeedbackSampleRate` – Sample rate percentage (0-100) of successfully delivered messages.
The following attributes only apply to `APNs` token-based authentication:  
+  `ApplePlatformTeamID` – The identifier that's assigned to your Apple developer account team.
+  `ApplePlatformBundleID` – The bundle identifier that's assigned to your iOS app.
