# SetEndpointAttributes
<a name="API_SetEndpointAttributes"></a>

Sets the attributes for an endpoint for a device on one of the supported push notification services, such as GCM (Firebase Cloud Messaging) and APNS.

## Request Parameters
<a name="API_SetEndpointAttributes_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 endpoint attributes. Attributes in this map include the following:  
+  `CustomUserData` – arbitrary user data to associate with the endpoint. Amazon SNS does not use this data. The data must be in UTF-8 format and less than 2KB.
+  `Enabled` – flag that enables/disables delivery to the endpoint. Amazon SNS will set this to false when a notification service indicates to Amazon SNS that the endpoint is invalid. Users can set it back to true, typically after updating Token.
+  `Token` – device token, also referred to as a registration id, for an app and mobile device. This is returned from the notification service when an app and mobile device are registered with the notification service.
