description: "Enable and configure the Integration API for external access"

The Integration API provides programmatic access to Pangolin functionality. It includes OpenAPI documentation via Swagger UI.

## Enable Integration API

Update your Pangolin configuration file:

```yaml title="config.yml"
flags:
  enable_integration_api: true
```

If you want to specify a port other than the default `3004`, you can do so in the config as well:

```yaml title="config.yml"
server:
  integration_port: 3004 # Specify different port
```

## Configure Traefik Routing

Add the following configuration to your `dynamic_config.yml` to expose the Integration API at `https://api.example.com/v1`:

```yaml title="dynamic_config.yml"
http:
  middlewares:
    redirect-to-https:
      redirectScheme:
        scheme: https

  routers:
    int-api-router-redirect:
      rule: "Host(`api.example.com`)"
      service: int-api-service
      entryPoints:
        - web
      middlewares:
        - redirect-to-https

    int-api-router:
      rule: "Host(`api.example.com`)"
      service: int-api-service
      entryPoints:
        - websecure
      tls:
        certResolver: letsencrypt

  services:
    int-api-service:
      loadBalancer:
        servers:
          - url: "http://pangolin:3004"
```

## Access Documentation

Once configured, access the Swagger UI documentation at:

```
https://api.example.com/v1/docs
```
