The API Catalog is a centralized dashboard for monitoring, analyzing, and governing APIs across your organization. It aggregates runtime analytics from Postman CLI runs, CI/CD pipelines, and spec linting results into actionable insights. The API Catalog works with Agent Mode, so you can ask questions about your APIs and get help with fixes when something is broken.
To access the API Catalog, from 
Home, click API Catalog.
What’s inside
The API Catalog consists of these main components:
- Catalog list
- Governance groups
- System environments
Catalog list
The API Catalog shows all of your discovered services. You can filter and sort your API list in different ways. Use tags to mark which APIs you want to manage. The catalog shows who owns each API. You can also see how APIs are connected to each other and check health metrics. The API Catalog also shows you which APIs aren’t properly managed with Postman Insights (if you have access).
You can do the following:
- Make views with your filters and tags.
- Show different information at once.
- Jump to the views you need.
Governance groups
Governance groups help you make and enforce rules for your API specs like OpenAPI. You can have different rules for different types of APIs, for example, one set of rules for public APIs and another for internal APIs.
This is how it works:
- Developers using Postman can see these rules in the Postman app.
- The Postman CLI can pull these rules and enforce them in the CI pipeline.
- You can configure the Postman CLI to block releases or trigger warnings.
- Rules help score how well your APIs follow your own standards.
System environments
System environments are your actual setups like production, staging, or beta. Setting these up helps Postman track your APIs correctly.
When you run tests on multiple APIs, for example, system environments help group the results so you can see how each API performs.
Discover APIs and services
The API Catalog automatically shows all of your Git-connected Postman workspaces. To add something to the catalog, connect your Postman workspace to your source code. The API Catalog also shows APIs from API gateways and APIs discovered through Postman Insights. You can also set up a Kubernetes cluster custom resource as a watcher. You can also add APIs manually.
To help get started quickly, the API Catalog provides the ability to discover services through multiple sources:
Using these workflows, you can find APIs that aren’t managed in Postman yet and add them to the catalog. Postman sends a pull request to the API owner’s repository. When the PR is accepted, a Git-connected project workspace is created, and the API shows up in the API Catalog.
View the project
A project displays all the data Postman knows about that API across development, test, and production.
Customize your view
Click 
View more actions in the list header to customize which columns appear in your view. Then, click the Select saved filters dropdown to save your view for easy access later. You can also switch between different environments (for example, staging or production) using the environment selector. For more information on customizing your view, see Customize your project view.
Individual projects provide the following information about your APIs:
-
Workspace analytics — View performance metrics, error rates, and activity across workspaces.
-
Endpoint health monitoring — Track p95 latency, error rates (4xx/5xx), and request volumes per endpoint.
-
CI/CD integration — Monitor GitHub Actions, GitLab CI, Jenkins pipeline runs with PR-level insights.
-
Spec linting — Aggregate OpenAPI specification quality scores and violation tracking.
-
System environments — Classify and filter data by canonical environments (prod, staging, beta).
-
chat — Ask Postman AI questions about your APIs and get help with fixes when something is broken.
