AWS SNS

Push a message to an SNS topic and fan it out instantly to every subscribed endpoint — SQS queues, Lambda functions, HTTP endpoints, email addresses, and SMS numbers simultaneously.

Provision a new SNS topic — standard or FIFO — with a chosen name, encryption settings, and delivery policy, ready to receive publishers and subscriptions.

Permanently remove an SNS topic and all its subscriptions, used to clean up ephemeral event channels after a campaign, test run, or tenant offboarding.

Return all SNS topics in the AWS account, paginated, giving the agent a live inventory to drive audits, routing logic, or cleanup passes.

Fetch the full attribute map for a specific topic — ARN, display name, subscription counts, delivery policy, KMS key, and effective policy — for auditing or conditional routing.

Update a topic's display name, delivery retry policy, KMS encryption key, or access policy without recreating the topic or losing existing subscriptions.

Register a new endpoint — SQS ARN, Lambda ARN, HTTP/S URL, email address, or phone number — as a subscriber to an existing SNS topic.

Remove a specific endpoint's subscription from a topic using its subscription ARN, immediately stopping message delivery to that endpoint.

Return all subscriptions in the account or filtered to a single topic, giving the agent a live map of who receives what for audits and routing decisions.

Fetch the attribute map for a specific subscription — confirmation status, raw message delivery setting, filter policy, and redrive policy — to verify configuration or drive conditional logic.

Update a subscription's filter policy, raw message delivery flag, or redrive policy without re-subscribing, enabling real-time routing adjustments on live traffic.

Send up to 10 messages to a topic in a single API call, each with independent subject lines, message attributes, and message structure — reducing round-trips by 10x on high-volume publishing scenarios.

Register a mobile device token (APNs or FCM) with an SNS Platform Application, returning an endpoint ARN the agent can use to push notifications directly to that device.

Deliver a transactional or promotional SMS to any phone number globally via SNS, with control over sender ID, message type, and max spend per message.

Query whether a specific phone number has opted out of SNS SMS messages, letting the agent skip opted-out numbers before a bulk send to avoid violations and wasted spend.

Retrieve the full list of phone numbers that have opted out of SMS from this AWS account, providing a definitive suppression list for compliance and CRM sync.

Grant one or more AWS account principals permission to publish or subscribe to a topic, enabling cross-account and cross-service event bus access without manual IAM policy edits.

Fires when SNS successfully delivers a message to a subscribed endpoint — SQS queue, Lambda, HTTP/S URL, or email — confirming the fan-out reached its destination.

Fires when SNS cannot deliver a message to a subscribed endpoint after exhausting all retry attempts, enabling the agent to recover the payload before it is discarded.

Fires when a new SNS topic is provisioned in the account, letting the agent register it in the service catalog, apply default policies, or alert the team.

Fires when an HTTP/S or email endpoint responds to the SNS confirmation request, signalling that the subscription is active and ready to receive messages.

Fires when an SMS is dispatched from the account, enabling the agent to log the send, check spend against budget caps, or trigger follow-up workflows on successful dispatch.

Fires when a CloudWatch alarm transitions state (OK → ALARM → INSUFFICIENT_DATA), routing infrastructure events through SNS to the agent for triage and response.

Fires when a message that could not be delivered to its intended subscription endpoint lands in the configured dead-letter SQS queue, enabling the agent to recover or replay the lost payload.

Fires when an attribute on an existing SNS topic — display name, delivery policy, encryption key, or access policy — is changed, enabling change-control and drift-detection workflows.
