 The Snyk API enables developers to automate Snyk processes to accomplish their specific workflows, ensuring consistency in both developer experience and platform governance. The [Snyk REST API ](rest-api/about-the-rest-api.md) and the [V1 API](v1-api.md) are available for you to use when you decide to use an API rather than the CLI or an integration. Both are available in the Snyk API [Reference](reference/). Additional endpoints are available in the [OAuth2 API reference](oauth2-api.md).
