Timely API
Timely is salon, spa, and beauty business software built around online booking, calendar scheduling, and payments. This page is an independent design exercise that asks what a well-designed Timely API could look like: the resources it would expose, the authentication it would need, and the workflows it could unlock. Below: a hypothetical endpoint design, the technical requirements a production implementation would face, the use cases programmatic access could serve, and where to start if your team needs this kind of access today.
This page is an independent analysis by Supergood of what a well-designed Timely API could look like. It draws on publicly available information, vendor materials, and general integration experience in this category. Nothing on this page describes an existing Timely product, and Supergood is not affiliated with or endorsed by the vendor. If the vendor offers an official API, we highly recommend it.
What is Timely?
Timely is salon, spa, and beauty business software built around online booking, calendar scheduling, and payments. Salons, spas, barbers, and beauty professionals use Timely to take online bookings, manage their appointment calendar and staff rosters, accept payments through an integrated point of sale, track client history and preferences, run SMS and email marketing campaigns, and report on appointments and sales.
Core product areas include:
- Online booking and integrated booking widgets for client self-service appointments
- Calendar and appointment scheduling with staff rosters and confirmation emails
- Point of sale and payments to accept payment quickly and securely
- Client management tracking client history and preferences
- Marketing, SMS campaigns, automated reminders, and a loyalty/rewards system
- Staff management, inventory management, and reporting on appointments and sales
An API for a platform like this would naturally organize around its core data entities:
- Appointments, Bookings, Services, Service Categories
- Clients/Customers, Client History, Preferences, Consultation Notes
- Sales, Payments, Invoices, Gift Vouchers, Loyalty Points
- Staff, Rosters, Working Hours, Availability
- Products, Stock/Inventory, Suppliers
- Marketing Campaigns, SMS Messages, Reminders, Reward Vouchers
The Timely Integration Challenge
Salons and spas run their entire front desk on Timely, but turning its booking- and POS-driven workflows into API-driven automation is non-trivial:
- OAuth and developer setup gates: API access requires admin-level configuration of an app and redirect URI under Settings, which many integrators are not set up to manage
- Booking-widget and mobile-first data: Much of the client experience flows through online booking widgets and mobile apps rather than a documented data export
- Per-business configuration: Services, pricing, rosters, and packages are tailored per salon, generic integrations break across accounts
- Token and session handling: OAuth2 access tokens expire and must be refreshed, complicating long-running headless automation
- Endpoint coverage variability: The public API surfaces some entities cleanly while other workflows live only behind the web and mobile UI
- Payments and sales reconciliation: POS transactions, gift vouchers, and loyalty points need careful matching back to appointments and clients
What a Timely API Could Look Like
If Timely exposed a modern, general-purpose API, the integration challenges above suggest what it would need to get right. This is a design sketch, not documentation of anything that exists today:
- First-class authentication: session handling with support for MFA and enterprise sign-on where the platform uses them
- Consistent resources: normalized JSON schemas and pagination across the platform's core objects
- Reliable writes: idempotency keys and validation that mirrors the platform's own workflow rules
- Entitlement awareness: endpoints scoped to what each customer's licensing actually permits
The endpoint sketches, technical requirements, and use cases below flesh out this hypothetical design.

Potential API Endpoints
Authentication
/authenticateWould authenticate to a Timely account using login credentials or OAuth2 and obtain a session token for downstream calls.
Scheduling
/appointmentsWould list appointments and bookings with filters for staff, service, client, status, and date range.
Scheduling
/create_appointmentWould create a new appointment or booking against a service, staff member, and client with the configured pricing.
Clients
/clientsWould retrieve client records including history, preferences, and contact details with search and filter parameters.
Sales
/salesWould pull point-of-sale transactions, payments, invoices, gift vouchers, and loyalty activity across date ranges.
Staff
/staffWould list staff members, rosters, working hours, and availability used to drive scheduling and reporting.
Use Cases
Sync appointments and client data into your stack
- Pull appointments, bookings, and services into a single warehouse or CRM - Stream new bookings and cancellations to downstream reminder and marketing tools - Reconcile client history and preferences across locations for a unified client view
Automate point-of-sale and payments reporting
- Sync sales, payments, and invoices from Timely POS into accounting and BI systems - Match gift vouchers and loyalty points back to clients and appointments - Surface daily takings and outstanding balances to finance dashboards
Power booking and staff workflows
- Push new bookings created in third-party booking flows into Timely's calendar - Pull staff rosters and availability to drive external scheduling tools - Trigger automated reminders and confirmations when appointments change
Drive marketing and loyalty campaigns
- Export client lists, visit history, and spend for targeted SMS and email campaigns - Sync loyalty points and reward vouchers into a unified rewards program - Trigger rebooking and birthday outreach based on appointment activity
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require login credentials and OAuth2 access/refresh tokens with managed session handling, with MFA where enabled
Connectivity
Would build on authenticated browser flows plus Timely's public API surfaced where exposed by the account
Response format
Normalized JSON across appointment, client, sale, service, and staff objects
Rate limits
Adaptive throttling tuned to your account to avoid Timely-side limits
Session management
Would need automatic OAuth2 token refresh, session continuity, and credential rotation
Data freshness
Near real-time pulls for appointments, sales, and clients with optional scheduled batch syncs
Security
Encrypted credential vault, scoped access tokens, SOC 2-aligned controls, and audit logging
Webhooks
Event-style callbacks for new bookings, cancellations, sale completions, and client changes
Latency
Design target: sub-second reads on cached entities; multi-second writes when posting bookings and sales
Throughput
Design target: horizontally scaled workers sized to multi-location salon and spa volume
Reliability
Retry, backoff, and idempotency keys for bookings, payments, and client updates
Versioning
Clear versioning and change management would matter as Timely evolves
Frequently asked questions
Sales, payments, gift vouchers, and loyalty activity are normalized and matched back to the originating client and appointment, so finance and rewards data stay reconciled.
Availability of official interfaces varies by product, plan, and licensing. Many platforms in this category gate access behind partner programs or paid modules, and there is often no broadly available, self-serve public API. Check the vendor's developer resources for current offerings.
The hard parts would be authentication (MFA, session management, enterprise controls), consistent schemas across the platform's products, and write semantics that reconcile the way the platform's own workflows do.
