An endpoint is the address that you specify for a subscription to receive messages. When messages are published to a topic, MNS pushes the messages to the specified endpoints. You can specify an endpoint for multiple subscriptions.
- HttpEndpoint
-
- You can use HTTP URIs as endpoints.
- Syntax:
http://$example.com[/uri]. You can specify a multi-level directory for a URI. - Limit: The directory that you specify in a URI cannot start with mns-reserverd-.
- MNS sends HTTP requests to specified endpoints. You can process the requests at the endpoints.
- QueueEndpoint
-
- You can use MNS queues as endpoints.
- Syntax: acs:mns:{REGION}:{AccountID}:queues/{QueueName}.
- Limit: Messages can be pushed only to the queues that belong to the same region and account as topics.
- MNS writes messages to the specified queues. You can call the ReceiveMessage operation to receive the messages. For more information, see Push messages to a queue.
