Everything in Altegio is reachable from outside: your data through the API, changes through webhooks, your numbers through MCP
Query and update your data – appointments, clients, services, schedules – and build your own tools on top of the platform to fit even the most rapidly changing workflows
Connect Altegio Pro MCP to Claude, ChatGPT or Cursor, then ask it for a chart or a breakdown of your own numbers
The Altegio team builds a custom client app based on Altegio.me and publishes it under your name, logo and design in the App Store and Google Play
Third-party applications you can connect in three clicks, categorised by what they do: AI assistants, messenger bots, analytics, VoIP, payments and more
Altegio pushes an event to your own tool the moment something changes – a product created, a service deleted – so your tool never has to poll for changes
A full REST API reference with methods, parameters and examples, so your developer starts from the documentation rather than from a support ticket
Build a tool over a weekend, wire in a partner app, or let an AI assistant run the account for you – all of it inside the permissions you grant. Your API token is waiting in the trial account from day one
Try 7 days freeAltegio is built to work with AI: connect an assistant that answers every client and fills the calendar itself, around the clock and in the language the client wrote in
AI receptionists answer clients around the clock in WhatsApp, Telegram, Instagram and on your site, advise on services, and create, confirm, reschedule and cancel appointments in Altegio
The assistant reads your services, your team members and the slots that are really free, so it books straight into your calendar – no double-booking, and nothing for the front desk to re-enter
AI assistants have their own category in the Integrations Hub, so you choose the one that fits, chat or voice, connect it in a few clicks and pay the partner directly. Most offer a 7-day trial
Every reply the assistant sends and every slot it books runs on a token with exactly the rights you grant, so a fuller calendar never costs you control of the account. The same open API is open to an assistant of your own
Your brand on the booking screen and the flow behind it, in your colours and with your booking logic
Upload your logo and the image the widget opens with, while photos of your services and your work samples come from the service settings
Set any interface colour for the widget, and switch it between a Light and a Dark theme
Create as many booking forms as you need – by service category, by campaign partner or one per team member, so each of them promotes their own services and takes appointments on a link of their own
Booking-form events can be sent to your Google Analytics 4 and Meta Pixel, so an appointment lands in your reports as a conversion
Pick one of three booking formats – Menu, Step-by-step or Short step-by-step – and set the order of the steps, so the decision that matters most comes first
Client data fields are yours to choose, and custom fields can be created at chain and location level, each with its own type and a key for integrations

Businesses that outgrow the settings go further and inject their own scripts, down to the animation of the widget – far enough that clients take the result for a mobile site of your own. Set your colours, logo and booking steps in a trial account
Try 7 days freeThree ways to put the widget on a site you already have, from a button in the corner to a form inside the page
A round booking button whose position, colour and animation are yours to set
If your site already has its own button design, the booking form opens from it
The booking form sits inside one of your pages and reads as part of the site rather than as a pop-up
A short branded link instead of a technical URL, and a separate link for every case
Your subdomain. Pick the name you want clients to see, and it becomes part of every booking link you share
Main link. Your whole service catalogue, for the link in your profile and the button on your website
Event link. A link to your group events, separate from the individual-appointment catalogue
Per-service link. One category or one service, for a campaign that advertises exactly that
Team member link. One team member's own page or profile
Company form and chain widget. One entry point for a chain, where the client picks the branch first
Each link is configured on its own, so the link in a campaign can behave differently from the link on your website. Each of them is a separate booking page in your brand style, and the client sees only your offers
Availability is a set of rules you set: when clients can book, which services are open to whom, and what protects you from a no-show
One location can run different availability for different team members
Cancelling in time costs the client nothing; a late cancellation or a no-show is charged automatically, and your team can waive the fee when that is fair
Set the days and the hours when online booking is open at all
Take a percentage or a fixed amount on the services and team members you choose. Altegio charges no fee of its own: the payment runs through a provider you connect
Give a service a date range plus a time window, and it can be booked only inside that period
Online booking for a service can be restricted to clients who hold an active membership for it

Write your booking rules and a no-show policy in a trial account
Try 7 days freeAn interface that adjusts to the front desk that spends the whole day in the schedule
Zoom the schedule in or out: the grid runs at 5-, 10- or 15-minute steps, so short services and long ones both stay readable
Set whichever suits your business type as the default, so a business that books rooms, chairs or equipment opens on the resource rather than on the person
Appointment statuses carry their own colours, and appointments and events carry categories you create yourself, so a full day reads at a glance in colour codes your team already knows
Reach the features you use most in two or three clicks: pick your favourites both in the main menu and in the client's appointment window
Payroll is rule-driven, so pay comes out the way you already pay rather than the way a template assumes
Rules and criteria. You define the rules and criteria, combine them into calculation charts, and assign a chart to a team member
Different rates for different work. A rule can apply to the services you choose, so a category that earns differently is paid differently
Individual terms for your team members. Two people doing the same service can sit on two different charts
What counts and what does not. A rule can include or exclude the discount the client received, and the part paid with bonuses, certificates or memberships, so every payout can be traced back to the rule behind it
The mechanics, with every rule type spelled out, live on the Payroll page
Try 7 days freeRewrite every template, pick the channel it goes out on, and let it reach the client in the language they booked in
Every notification type carries its own template, its own channels and its own sending conditions, so every message sounds like your business, not like a system
A follow-up invitation to clients who cancelled or did not show up goes out immediately after the cancellation, after 1 to 24 hours, or after 2 to 7 days
A client who books in their own language keeps reading in it: the widget, your translated service catalogue and the consent text all follow the language they chose
Email is free and needs no integration. SMS, WhatsApp and Viber run through a provider you connect from the Integrations Hub, on that provider's own terms
Rewrite your first template and pick its channel in a trial account

Who else is on the screen
Only you – no competing businesses sitting next to your listing
Your competitors are one tap away, ready to take the booking
Who sets the price
You set your own prices, with no third-party pressure
Pricing bends to the marketplace’s rules, discounts and commissions
Push notifications
Targeted push to the client segments you choose, in your own voice
Generic platform messaging you cannot target or brand
Loyalty Program
Your Loyalty Program, memberships and bonuses live inside the app
Loyalty stays with the marketplace and follows the client, not you
A branded client app is a development project built by the Altegio team and published under your own name and store accounts. See how it works on the branded app page
The settings that let you set the rules for every team member in your business: from managers to receptionists and specialists
Every section – Settings, Staff, Finance, Inventory, Loyalty, Online booking – carries its own permission set, and even report visibility follows the role
Billing follows what a team member can do, not their job title: everyone who takes bookings or changes data counts toward your plan, and view-only access does not
Services, categories, products and the Loyalty Program are configured once in the chain interface and copied down to the locations

Your own consent text per language, and the client data fields your paperwork needs
Appointment statuses in your own colours, so a full day reads at a glance

Group events plus a service catalogue translated per language
A per-service link for the job you advertise, and a calendar that opens on resources

Haven't found the one thing you came for on this page? Tell us what it is and we’ll find a way with you – a setting, an integration, or something built on the API
Nearly everything is a setting: the Appointment Calendar size and view, the booking widget and its steps, your booking address, notification templates, booking rules, Payroll rules and permissions. Beyond that there is an open API
No. The calendar, the widget, the booking rules, the form fields, the templates and the Payroll rules are all settings you change yourself. A developer is only needed for your own integration or an app built on the API
No. Colour choices belong to what your clients see: the booking widget has its own interface colour and a Light or Dark theme, and appointment statuses carry colours in the calendar. The menus your team works in are not re-skinned
Yes. Altegio Pro MCP plugs your account into Claude, ChatGPT, Cursor or an agent of your own, and the same open API with webhooks is what you vibe-code against when a feature is missing – a report, a bot or an integration built over a weekend. All of it runs on a token with exactly the permissions you grant
Three steps: pick a format – a floating button, your own button or a form embedded in the page – copy the code snippet from your online booking settings and paste it into your site. It works on any site that accepts an HTML snippet, WordPress, Wix, Tilda and Squarespace included
The settings themselves come with your subscription: the calendar, the widget, your booking links, the rules, the templates and the Payroll rules. Paid separately are a branded mobile app, SMS through an SMS provider, and the payment provider’s own fee on prepayment
