An endpoint is the address that you specify for a subscription to receive messages. When messages are published to a topic, Message Service (MNS) pushes the messages to the specified endpoints. You can specify the same 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 the 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 about how to push messages and specify endpoints, see Push messages to queues.
