Simple Message Queue (formerly MNS):API overview

最終更新日:Nov 04, 2025

API standard and pre-built SDKs in multi-language

The OpenAPI specification of this product (Mns-open/2022-01-19) follows the RPC standard. Alibaba Cloud provides pre-built SDKs for popular programming languages to abstract low-level complexities such as request signing. This enables developers to call APIs using language-specific syntax without dealing with HTTP details directly.

Custom signature

If your specific needs, such as a customized signature, are not supported by the SDK, manually sign requests using the signature mechanism. Note that manual signing requires significant effort (usually about 5 business days). For support, join our DingTalk group (ID: 147535001692).

Before you begin

An Alibaba Cloud account has full administrative privileges. A compromised AccessKey pair exposes all associated resources to unauthorized access, posing a significant security risk. Create a Resource Access Management (RAM) user with API-only access and use RAM policies to apply the principle of least privilege (PoLP). Alibaba Cloud accounts are only used when explicitly required.

To call APIs securely, configure the following:

Topic management

API

Title

Description

CreateTopic CreateTopic You can call the CreateTopic operation to create a topic.
SetTopicAttributes SetTopicAttributes Modifies the attributes of a topic.
GetTopicAttributes GetTopicAttributes You can call the GetTopicAttributes operation to retrieve the properties of a topic.
DeleteTopic DeleteTopic Deletes a topic.
ListTopic ListTopic Queries a paginated list of topics in an Alibaba Cloud account.

Queue management

API

Title

Description

CreateQueue CreateQueue The CreateQueue operation creates a queue.
SetQueueAttributes SetQueueAttributes Modifies a queue.
GetQueueAttributes GetQueueAttributes Retrieves the properties of an existing queue.
DeleteQueue DeleteQueue Deletes a queue.
ListQueue ListQueue You can call the ListQueue operation to list all queues in a specified Alibaba Cloud account. The results are paginated.

Subscription management

API

Title

Description

Subscribe Subscribe Creates a subscription to a topic.
SetSubscriptionAttributes SetSubscriptionAttributes The SetSubscriptionAttributes operation modifies the properties of a subscription.
GetSubscriptionAttributes GetSubscriptionAttributes Queries the attributes of a subscription.
Unsubscribe Unsubscribe Deletes a subscription.
ListSubscriptionByTopic ListSubscriptionByTopic Queries all subscriptions to a topic. The subscriptions are displayed by page.

Access point management

API

Title

Description

DisableEndpoint DisableEndpoint You can call this operation to disenable the endpoint of a type. After the endpoint is disabled, all requests from the endpoint are blocked and an error is returned.
EnableEndpoint EnableEndpoint You can call this operation to enable the endpoint of a type. If the endpoint is enabled, requests from the endpoint that are included in the access control lists (ACLs) are not blocked.
GetEndpointAttribute GetEndpointAttribute GetEndpointAttribute
RevokeEndpointAcl RevokeEndpointAcl You can call this operation to delete one or more ACL rules for the endpoint of a specified type.
AuthorizeEndpointAcl AuthorizeEndpointAcl You can call this operation to add one or more access control list (ACL) rules for the endpoint of a specified type.

Event Notification Management

API

Title

Description

GetEventRule GetEventRule Retrieves an event notification rule.
ListEventRules ListEventRules Queries a list of event rules.
CreateEventRule CreateEventRule Creates an event rule.
DeleteEventRule DeleteEventRule Deletes an event rule.
