Services do not require shipping or pharmacy dispatch. ## OpenAPI ````yaml /openapi.yaml post /subscriptions openapi: 3.1.0 info: title: VitaRelay API version: 2.0.0 description: | The VitaRelay REST API. **Base URL:** `https://vitarelay.com/api/public/v1` ## Authentication All requests require a Bearer API key: ```text Authorization: Bearer vr_live_xxxxxxxxxxxxxxxx ``` Keys are issued per organization. `vr_live_` keys act on production data. `vr_test_` keys operate a fully-isolated **sandbox** (see below). ## Pagination List endpoints are cursor-based. Pass `limit` (default 50, max 100) and `cursor` (the `next_cursor` from the previous page). When `next_cursor` is `null` there are no further pages. All resource ids are UUIDs. ## Idempotency Write endpoints accept your own external identifiers — `external_patient_id`, `external_intake_id`, `external_order_id`. These act as idempotency keys: replaying a request with the same external id returns the original resource (HTTP `200` instead of `201`) rather than creating a duplicate. ## Rate limiting Write endpoints are rate limited per API key — default **60 requests per minute** (fixed window). Exceeding the limit returns `429 rate_limited` with `Retry-After`, `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` headers. Read endpoints are not rate limited in v1. ## Sandbox With a `vr_test_` key, writes never create real patients, intakes or orders and never charge a card. They return synthetic ids (`sandbox_pat_…`, `sandbox_int_…`, `sandbox_ord_…`) and include `"sandbox": true` in the response. Sandbox objects advance through a simulated lifecycle that fires real webhook deliveries to your endpoint (`intake.reviewed`, `order.paid` → `order.shipped` → `order.delivered`) with `"sandbox": true` in the payload. In sandbox, reference a patient by `external_patient_id` or by the returned `sandbox_pat_…` id. ## Webhooks Outbound webhooks are configured in the VitaRelay admin UI (there is no webhook management API). Events: `order.paid`, `order.shipped`, `order.delivered`, `order.exception`, `intake.reviewed`. Each delivery is signed with HMAC-SHA256 over the raw body and carries the headers `X-VitaRelay-Signature: sha256=`, `X-VitaRelay-Event`, `X-VitaRelay-Delivery` (event id) and `X-VitaRelay-Timestamp`. Failed deliveries are retried with exponential backoff and dead-lettered after the maximum attempts. contact: name: VitaRelay Support email: info@vitarelay.com servers: - url: https://vitarelay.com/api/public/v1 description: Production security: - bearerAuth: [] tags: - name: Patients description: Patient records scoped to your organization. - name: Intakes description: Intake form submissions.
