Sollis Health Member Portal API
First-party backend API for the Sollis Health Member Portal (mp.sollishealth.com), the members-only web application used to book appointments, view records and manage membership. Authentication is Microsoft Entra External ID (Azure AD B2C) under the sollishealthprod tenant, with an application scope of Appointment.All. The host is live and returns a JSON 404 envelope on unknown paths; no OpenAPI, Swagger, GraphQL or other machine-readable contract is published at any probed location. This is an internal product API, not a public developer program.
