# Enable Integration API (/self-host/advanced/integration-api)

> 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 [#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 `3003`, you can do so in the config as well:

```yaml title="config.yml"
server:
  integration_port: 3003 # Specify different port
```

## Configure Traefik Routing [#configure-traefik-routing]

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

```yaml title="dynamic_config.yml"
  routers:
    # Add the following two routers
    int-api-router-redirect:
      rule: "Host(`api.example.com`)"
      service: int-api-service
      entryPoints:
        - web
      middlewares:
        - redirect-to-https
        - badger # If you have Badger >=1.3.0 and it's enabled in the middlewares section of the dynamic config

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

  services:
    # Add the following service
    int-api-service:
      loadBalancer:
        servers:
          - url: "http://pangolin:3003"
```

## Access Documentation [#access-documentation]

Once configured, access the Swagger UI documentation at:

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