# DSAR > Developer-first Data Subject Access Request engine: APIs, SDK, lifecycle, policy, and webhooks. ## Overview - Self-hostable runtime with tenant-safe persistence and storage adapters. - OpenAPI generated at GET /spec.json with interactive docs at GET /docs. - Inbound channels (Resend, Slack) and outbound delivery wired through the same lifecycle. - Auth split between machine bearer tokens and trusted-host identity projection. ## Best Starting Points - [Getting Started](/docs/guides/getting-started.md): Stand up the runtime and walk through your first request. - [Auth Model](/docs/architecture/auth-model.md): How machine and trusted-host identity lanes work. - [Requests API](/docs/reference/api/requests.md): Core DSAR request lifecycle endpoints. ## Agent Guidance Start with the getting started guide for a runnable local runtime, then use the architecture docs to understand contracts and the API reference for endpoint-level behavior. ## When to use DSAR Use DSAR when you need to build or operate data subject rights workflows, including request intake, identity verification, data collection, delivery, appeals, retention, and audit records. - Start with the getting started guide when you need a runnable self-hosted runtime. - Use the API reference and the `/spec.json` exposed by your hosted DSAR runtime when you need endpoint inputs, outputs, authentication, or error contracts. - Use the integration guides when choosing inbound channels, outbound delivery, storage, rate limiting, or authentication adapters. - Use the architecture guides when extending the runtime, persistence layer, policy packs, or adapter contracts. - Do not use DSAR for cookie consent or consent-banner implementation. Use [c15t](https://c15t.com/docs) for that job. ## Socials - [Bluesky](https://bsky.app/profile/inth.com): Follow @inth.com. - [X / Twitter](https://x.com/inth): Follow @inth. - [Discord](https://discord.gg/CnVvE4W3U7): Join the Inth community. - [GitHub](https://github.com/inthhq/dsar): View the DSAR repository.
