title: FUSE Brand API (External) Program Templates & Titration API
version: 1.0.0
description: 'Server-to-server API exposing the FUSE brand-admin surface so a single brand/tenant can build its own admin frontend. Every request is authenticated with an API key bound to exactly one clinic; all data is auto-scoped to that clinic and cannot reach another brand''s data. Isolation is enforced by application-layer clinic filtering on every query.
COVERAGE: 218 operations across 180 paths, and EVERY ONE is available to every brand. There is no per-clinic enablement step. What governs access: your API key and its scopes, the clinic the key belongs to (every read and write is filtered to it), your plan''s entitlements for the two commercially-gated areas — Affiliates (`AFFILIATES_TIER_REQUIRED`) and CRM Connect (`CRM_TIER_REQUIRED`) — and rate limits.
AUTH: the external /api/v1 surface uses an API key (`x-api-key`, ApiKeyAuth). Key management (/api-keys) and /auth/signin live at the API root and use a brand-admin JWT (BearerAuth); /auth/signin itself is unauthenticated.
SCOPES: every key carries scopes; read-only is the default and mutating endpoints require the `write` scope (403 INSUFFICIENT_SCOPE otherwise). Keys default to a 1-year expiry.
RATE LIMITING: every endpoint may additionally return `429 Too Many Requests` with a `Retry-After` header; 429 is not repeated on each operation below.
PLATFORM FIELDS: product cost, fees, pharmacy routing, doctor questions and FUSE approvals are set by FUSE, not by the brand. Any write (POST/PUT/PATCH/DELETE) whose JSON body carries one of those fields at any depth — for example `pharmacyPrice`, `shippingFeeUsd`, `coolerFeeUsd`, `pharmacyId`, `preferredPharmacyId`, `pharmacyProvider`, `requiredDoctorQuestions`, `facilitationFee`, `placeholderPrice`, `legalBusinessName`, `isTemplate` or `tenantManagerApproved` — is refused with `403 PLATFORM_FIELD`, whose `fields` array lists the offending paths; remove them and resend. (One exception: `POST /api/v1/products` still accepts the `pharmacyPrice` its schema requires, and ignores it.) 403 PLATFORM_FIELD is not repeated on each operation below.'
