**Request a New Spec:** Want us to build an official spec for an API? Submit a request via this [Google Form](https://docs.google.com/forms/d/e/1FAIpQLScIgkpTC6C-nWaW6atc5eLFl3uUNiIakw37WL69HuPUks08aQ/viewform?usp=dialog) or open a [GitHub issue](https://github.com/slingdata-io/sling-cli/issues) (select the API Spec option).
{% endhint %}

{% hint style="info" %}
**Build Your Own API Spec:** You can create custom API specs to connect to any REST API. See the [API Specs documentation](https://docs.slingdata.io/concepts/api-specs) to learn how to build your own, or use [AI to build specs automatically](https://docs.slingdata.io/sling-cli/ai#building-a-custom-api-connector).
