# Identity & Preference Centre > An identity and preference management service. People sign in, see what > data is held about them, and control how they are contacted. ## For automated clients This service is API-first. If you are trying to accomplish something rather than read about it, use the API rather than parsing these pages. - [OpenAPI specification](https://portal.autom8ion.uk/openapi.json) — every endpoint, with schemas - Authentication: bearer API key, issued per tenant by that tenant's administrator - Format: send `Accept: application/json` or `Accept: text/markdown` to any public page for a structured response ## Data protection This service processes personal data under UK/EU GDPR. Data subjects can: - Request a copy of their data (Article 15 / 20) - Have it corrected (Article 16) - Have it erased (Article 17) - Withdraw consent to marketing at any time (Article 7) These are exercised through the tenant that holds the data, not through this service directly. ## Not available Person records, tenant lists, usage figures and administrative pages are not accessible without authentication, in any format. Requesting them with a different `Accept` header or User-Agent will not change that.
