# Custom Services

Some service can use a specific a component that provides some extra features by adding a `type` key to the service yaml
configuration and, where applicable, an apikey. Note that config.yml is exposed at /assets/config.yml via HTTP and any
apikey included in the configuration file is exposed to anyone who can access the homer instance. Only include an apikey
if your homer instance is secured behind some form of authentication or access restriction.

Available services are in `src/components/`. Here is an overview of all custom services that are available
within Homer.

If you experiencing any issue, please have a look to the [troubleshooting](troubleshooting.md) page.


## Common options

```yaml
- name: "My Service"
  logo: "assets/tools/sample.png"
  url: "http://my-service-link"
  endpoint: "http://my-service-endpoint" # Optional: alternative base URL used to fetch service data is necessary.
  useCredentials: false # Optional: Override global proxy.useCredentials configuration.
  type: "<type>"
```
