# Redthread Tattoo Redthread Tattoo takes online bookings for 4 services. Prices, opening hours and links below are generated from live data and cached for one hour. ## How to check availability (required) Do not drive the interactive /book pages to discover free slots. That flow is for people. It is slow, and it can miss staff-level availability. 1. Read the catalogue below. Every branch slug, service id and staff id a request needs is already in this file, so ONE live call remains — free slots change by the minute and are never in here. 2. Make that call: an anonymous GET on the availability API, no API key and no cookie. The response is wrapped as {"data": ...} and scoped to this business by the request host. 3. Hand the customer a booking deep link for the slot they picked (see below). Nothing is held or booked until they confirm it themselves with their deposit. Worked example — Consultation at Redthread Tattoo, week beginning 2026-10-12 (Monday): https://red-thread.uk/api/v1/locations/redthread/resources/week-multi?resource_ids=26,25&start=2026-10-12&service_id=44 One named person instead of the whole branch: https://red-thread.uk/api/v1/locations/redthread/resources/26/week?start=2026-10-12&service_id=44 ## Locations ### Redthread Tattoo - Address: 23 Division Street, Sheffield S1 4CV - Booking page: https://red-thread.uk/book - Branch slug: redthread (id: 9) Opening hours: - Monday: Closed - Tuesday: 10:00 AM – 6:00 PM - Wednesday: 10:00 AM – 7:00 PM - Thursday: 10:00 AM – 7:00 PM - Friday: 10:00 AM – 7:00 PM - Saturday: 11:00 AM – 7:00 PM - Sunday: Closed Services: - Consultation — 30 min — £0.00 (slug: consultation, id: 44) - Small Tattoo (up to 2 hrs) — 120 min — £120.00 (slug: small-tattoo, id: 45) - Half-Day Session — 240 min — £300.00 (slug: half-day-session, id: 46) - Piercing — 30 min — £40.00 (slug: piercing, id: 47) Staff: - Jules Marr (slug: jules-marr, id: 26) - Rae Sterling (slug: rae-sterling, id: 25) ## Booking deep links Hand a customer over with the booking page pre-filled: https://red-thread.uk/book?service=&resource=&date=YYYY-MM-DD&time=HH:MM - Every parameter is optional and best-effort. A parameter that no longer resolves (the staff member left, the service is not offered here, the slot was taken) is silently dropped to the next-best state — never an error page. - `service` — service slug or numeric id, matched in that branch's catalogue. - `resource` — staff slug or numeric id. `barber` is accepted as an alias for the same values; `resource` wins when both are present. - `date` — YYYY-MM-DD. Seeds the week and day, clamped to the booking window. - `time` — HH:MM, 24-hour, shop-local. Applies to the day named by `date`: with a valid `date` it pre-selects that slot if still available, ready for the customer to confirm; without one it does nothing. It never skips a step, and nothing is booked or held until the customer confirms with their deposit. - `promo` — a promo code; composes with all of the above. - A value that parses as a positive integer is read as an id, otherwise as a slug. Real slugs are name-derived and never pure digits. The link does not reserve anything. Phrase the hand-off honestly: the slot is subject to availability until the customer confirms with their deposit. ## Availability API reference Anonymous GET, no API key and no cookie. Every response is wrapped as {"data": ...} and scoped to this business by the request host. https://red-thread.uk/api/v1/locations//resources//week?start=YYYY-MM-DD&service_id= - Seven days from start, each with slots[]. Only slots with "status": "available" are bookable. Always pass service_id so slot lengths match the service. - No staff preference: https://red-thread.uk/api/v1/locations//resources/week-multi?resource_ids=&start=YYYY-MM-DD&service_id= returns every listed staff member's week in one call. At most 20 ids; any beyond that are ignored, so ask for the ones you care about. - Staff ids in resource_ids must belong to . Copy them from that branch's Staff list above, or from /api/v1/locations//resources?service_id=. - A service priced by variants (size bands, hair lengths — its catalogue line reads "from £X") has a duration PER TIER, so add &variant_id= or the slots come back at the base duration. The ids are in the `variants` array of /api/v1/locations//services; both week calls accept the parameter. If this file seems stale (it is cached for one hour), the catalogue is also live at /api/v1/locations, /api/v1/locations//services and /api/v1/locations//resources (there, ?service_id= drops staff who do not offer that service). There is deliberately no search parameter — match names over these small lists yourself. ## Links - Sitemap: https://red-thread.uk/sitemap.xml - Team page: https://red-thread.uk/team
