----------------

To bring your APIs and services into the API Catalog, you connect your Postman workspace to your source code. You can do that in the following ways:

* [API gateways](/docs/api-catalog/connect/gateway/) — Connect to your API gateway, and the API Catalog automatically shows all APIs in that gateway.
* [Postman Insights](/docs/api-catalog/connect/insights/) — Install the Postman Insights Agent and configure it for your Kubernetes deployment as a sidecar or DaemonSet.
* [Git-connected workspaces](/docs/api-catalog/connect/workspace/) — Connect your Postman workspace to your Git repository. The API Catalog automatically shows all APIs in that repository.
* [Cluster Watcher](/docs/api-catalog/connect/watcher/) — Set up a Kubernetes cluster custom resource as a watcher. The API Catalog automatically shows all APIs in that cluster.

The following table summarizes the differences between these methods:

| Method          | Setup   | Access Required | Best For                                      |
| --------------- | ------- | --------------- | --------------------------------------------- |
| Cluster Watcher | Minimal | Basic K8s API   | Fast onboarding, Git integration              |
| Insights Agent  | Complex | Elevated access | Traffic monitoring, detailed analytics        |
| API Gateway     | Medium  | Gateway access  | Spec-first teams with existing infrastructure |
