Creates a platform application object for one of the supported push notification services, such as APNS and GCM (Firebase Cloud Messaging), to which devices and mobile apps may register. You must specify PlatformPrincipal and PlatformCredential attributes when using the CreatePlatformApplication action.

• For ADM, PlatformPrincipal is client id and PlatformCredential is client secret.

• For Baidu, PlatformPrincipal is API key and PlatformCredential is secret key.

• For APNS and APNS_SANDBOX using certificate credentials, PlatformPrincipal is SSL certificate and PlatformCredential is private key.

• For APNS and APNS_SANDBOX using token credentials, PlatformPrincipal is signing key ID and PlatformCredential is signing key.

• For GCM (Firebase Cloud Messaging), there is no PlatformPrincipal and the PlatformCredential is API key.

• For MPNS, PlatformPrincipal is TLS certificate and PlatformCredential is private key.

• For WNS, PlatformPrincipal is Package Security Identifier and PlatformCredential is secret key.

You can use the returned PlatformApplicationArn as an attribute for the CreatePlatformEndpoint action.
