Customer gems balance and catalogue, public active offers, and admin offer management.

Loyalty & Offers

Two related areas: the gems loyalty programme (a customer's own balance, transaction history, and the redeemable-services catalogue) and offers (a public list of active promotions plus manager-only CRUD).

Base URLs: the customer endpoints (GET /api/gems, public GET /api/offers) are served from https://theroyalglow.in. The admin offer management endpoints are served from https://admin.theroyalglow.in with no /api/admin/ segment — the subdomain is the namespace (e.g. admin.theroyalglow.in/api/offers). Note /api/offers therefore exists in both apps: a public read on theroyalglow.in and role-gated CRUD on admin.theroyalglow.in. Money is an integer in paise (₹1,000.00 = 100000). Calendar dates are YYYY-MM-DD on input; date-mode columns serialise back as UTC-midnight ISO strings (e.g. "2026-06-30T00:00:00.000Z"). The role hierarchy is customer < staff < receptionist < manager < owner < developer.

Gems rules. Customers earn 1 gem per ₹100 invoiced (floor), on service invoices only — never on membership purchases or sessions. Gems expire 365 days after they are earned. Redemption is against specific catalogue services, not a rupee discount, and gems cannot be combined with an offer on the same booking.

GET `theroyalglow.in/api/gems`

Returns the signed-in customer's own loyalty summary, a paginated transaction history, and the redeemable-services catalogue. Strictly scoped to session.user.id — it never exposes another customer's data. A loyalty account is created on first call, so a brand-new customer sees zeros rather than an error.

Minimum role: customer (requireSession)

GET /api/gems?page=1&pageSize=20

Query parameters

Prop

Type

Response

data.summary is the balance plus lifetime totals (zeros if the account was just created). data.transactions are newest-first; invoiceNumber is null for non-invoice transactions (e.g. expired/adjusted). data.redeemable is the active gems-redeemable services catalogue. meta carries page and totalPages — there is no separate count query, so totalPages is page + 1 whenever a full page is returned (there may be more), otherwise page.

loyalty_tx_type is one of earned, redeemed, expired, adjusted.

Errors

GET `theroyalglow.in/api/offers`

Public list of active offers for the customer offers page. No auth. Returns only offers whose isActive flag is true and whose calendar date range includes today, ordered by displayOrder. Each offer carries its linked services.

GET /api/offers

Response

Each offer is the full offer row plus services ({ id, name }[]) and the convenience arrays serviceIds and serviceNames. The discount field that is populated depends on offerType:

percentage → discountPercentage (1–100)
flat → discountAmountPaise (paise)
combo_price → comboPricePaise (paise)

PATCH `admin.theroyalglow.in/api/offers/[id]`
