For Agents
Create and manage AWS CodeStar notification rules that deliver CodeCommit, CodeBuild, CodeDeploy, and CodePipeline events to SNS topics and Slack via AWS Chatbot. Backed by 13 endpoints across rules, targets, and event types.
Use for: I need to create a notification rule for CodePipeline failures, Subscribe a Slack channel to a CodeStar notification rule, List supported event types for CodeBuild, Unsubscribe an SNS topic from a notification rule
Not supported: Does not handle event generation, message formatting, or chat platform onboarding (configure AWS Chatbot separately) — use for routing AWS Developer Tools events to SNS and Chatbot targets only.
Jentic publishes the only available OpenAPI specification for AWS CodeStar Notifications, keeping it validated and agent-ready. CodeStar Notifications routes events from AWS Developer Tools (CodeCommit, CodeBuild, CodeDeploy, CodePipeline) to SNS topics and AWS Chatbot Slack channels via notification rules. The API covers notification rules, targets, event types, subscriptions, and tags, so an agent can wire up build- and deploy-event delivery to chat or downstream automation.
Install Jentic One Beta
Connect the AWS CodeStar Notifications to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS CodeStar Notifications, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with AWS CodeStar Notifications API.
Create notification rules that match Developer Tools events on a specific resource
Subscribe and unsubscribe SNS topic and AWS Chatbot Slack targets to a notification rule
List supported event types per service and resource type
Update existing notification rules to change event filters or status
Delete unused notification rules and orphaned targets
Tag notification rules for ownership and cost allocation
Use Cases
Patterns agents use AWS CodeStar Notifications API for, with concrete tasks.
★ Slack Alerts for Pipeline Failures
Engineering teams that live in Slack want a message every time a production CodePipeline fails. The agent creates a notification rule with the pipeline ARN as Resource, the relevant pipeline-execution-failed EventTypeIds, and a Target that points to a Slack channel registered with AWS Chatbot. ListEventTypes returns the canonical event-type IDs to use, removing guesswork.
Create a notification rule named pipeline-fail-alerts on the prod pipeline ARN with EventTypeIds for codepipeline-pipeline-pipeline-execution-failed and target a Slack chat configuration
Centralised Build Event Stream into SNS
When build, deploy, or repository events need to be processed by Lambda, EventBridge, or third-party tooling, an agent creates a notification rule with an SNS topic Target. Once events flow into SNS, downstream subscribers can transform or fan out the messages. Subscribe and Unsubscribe make it easy to add or remove SNS topics on existing rules without recreating them.
Subscribe SNS topic arn:aws:sns:..:dev-events to notification rule arn:aws:codestar-notifications:..:notificationrule/abc
Inventory and Cleanup of Stale Notification Rules
When repositories or pipelines are decommissioned, their notification rules can be left orphaned, sending events about non-existent resources. ListNotificationRules with a Filter on RESOURCE returns every rule on a given ARN, and DeleteNotificationRule removes those that are no longer relevant. Tagging rules with an owner helps the agent decide which can be safely cleaned up.
List all notification rules tagged Team=billing-svc and delete any whose Resource ARN no longer exists
AI Agent Integration via Jentic
Through Jentic, an AI agent uses CodeStar Notifications by searching for an intent like 'create a CodeStar notification rule', loading the CreateNotificationRule schema, and executing it with the resource ARN and event type IDs. Jentic signs the SigV4 request server-side using IAM credentials in the MAXsystem vault.
Search Jentic for 'create a CodeStar notification rule', load the CreateNotificationRule schema, and execute it for the prod pipeline ARN with pipeline-failed event type

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
AWS access key ID and secret are stored encrypted in the Jentic MAXsystem vault. Jentic computes the SigV4 signature server-side for every CodeStar Notifications call, so raw IAM credentials never enter the agent's context.
Intent-based discovery
Agents search by intent (e.g. 'create a CodeStar notification rule' or 'subscribe a Slack channel to pipeline failures') and Jentic returns the matching operation with its input schema, so the agent calls CreateNotificationRule or Subscribe directly without browsing AWS docs.
Time to first call
Direct AWS SDK integration: 1 day for SigV4, IAM, and event-type discovery. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using AWS CodeStar Notifications API through Jentic.
Why is there no official OpenAPI spec for AWS CodeStar Notifications?
AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call AWS CodeStar Notifications via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the AWS CodeStar Notifications API use?
CodeStar Notifications uses AWS Signature Version 4 (HMAC) signed requests with an IAM access key and secret. Through Jentic, IAM credentials live encrypted in the MAXsystem vault and the SigV4 signature is computed server-side, so the agent context never holds the raw secret.
Can I send Developer Tools events to Slack with this API?
Yes. Configure an AWS Chatbot Slack channel in the AWS console, then call CreateNotificationRule with a Targets entry containing TargetType=AWSChatbotSlack and the chat configuration ARN as TargetAddress. Specify EventTypeIds from ListEventTypes for the events you want to deliver.
How do I find the supported event type IDs for a CodeBuild project?
Call ListEventTypes with a Filter where Name=SERVICE_NAME and Value=codebuild. The response contains EventTypeId values such as codebuild-project-build-state-failed and codebuild-project-build-state-succeeded that you pass to CreateNotificationRule.
What are the rate limits for the AWS CodeStar Notifications API?
AWS enforces per-account, per-region throttling on CodeStar Notifications; throttled requests return ThrottlingException. The AWS SDKs that Jentic wraps implement exponential backoff automatically.
How do I wire up CodePipeline failure alerts through Jentic with an AI agent?
Run pip install jentic, then have the agent search for 'create a CodeStar notification rule', load the CreateNotificationRule schema, and execute it with the pipeline Resource ARN, the pipeline-execution-failed EventTypeIds, and a Target pointing to your SNS or AWS Chatbot Slack channel.
