It covers everything a customer can see and do — searching availability, placing bookings, managing their account, and more. --- ## When to use the Customer API Use the Customer API when you are **building something your customers interact with directly**: - **Custom booking flow** — embed a fully branded booking experience inside your own app or website instead of redirecting to anny - **Headless checkout** — drive the cart, checkout, and payment steps entirely from your own frontend - **Custom confirmation pages** — retrieve booking and order details after checkout to render a tailored confirmation - **Opening hours and availability on public pages** — display live schedule data on your website with no authentication required - **White-label experiences** — build lobby screens, kiosks, or mobile apps on top of the Customer API Many endpoints work **without any authentication**. For a custom OAuth2 client to authenticate your own users, contact [support@anny.co](mailto:support@anny.co) with your use case. --- ## Authentication — Optional Auth Most Customer API endpoints work without a token. Providing a customer bearer token unlocks personal data and additional actions: | Auth state | What's accessible | |---|---| | Anonymous | Availability, public resource/service info, booking lookup by number, checkout | | Customer token | Own bookings, account data, communities, passes, queue tickets | ``` Authorization: Bearer {customer_access_token} ``` To authenticate your own users, you need a custom OAuth2 client — contact [support@anny.co](mailto:support@anny.co). See the [Authentication guide](/developers/guides/authentication) for the full token flow. --- ## Customer API vs Admin API | Feature | Customer API | Admin API | |---|---|---| | **Use case** | End-user apps, booking widgets | Server-side automation, backend tooling | | **Auth** | Optional — many endpoints work without a token | Required — API token or OAuth2 | | **Identifiers** | Slugs, booking numbers, order numbers | Immutable UUIDs and integer IDs | | **Access** | Public and customer-owned data only | Full read/write | → [Go to the Admin API](/developers/api-reference/admin) --- ## Resource Identifiers The Customer API uses **human-readable identifiers** that appear in booking URLs: | Entity | Identifier | Example | |---|---|---| | Resources | Slug | `conference-room-berlin` | | Services | Slug | `hourly-desk-booking` | | Organizations | Slug | `acme-gmbh` | | Bookings | Booking number | `BB123456789` | | Orders | Order number | `BO123456789` | Use the Admin API if you need immutable internal IDs for storage in external systems. --- ## Starting Points | Guide | What it covers | |---|---| | [Getting Started](/developers) | First steps and quickstart | | [JSON:API Conventions](/developers/guides/json-api-conventions) | Request and response format | | [Authentication](/developers/guides/authentication) | Customer token flow, OAuth2, anonymous access | | [Availability & Booking Search](/developers/guides/availability) | Search open slots, filter by service and resource | | [Customer Booking Lifecycle](/developers/guides/customer/booking-lifecycle) | View, modify, and cancel bookings | | [Order & Checkout Flow](/developers/guides/customer/checkout) | Cart, checkout steps, payment | | [Plans & Subscriptions](/developers/guides/customer/plans-subscriptions) | Membership plans and recurring billing | | [Communities & Access Control](/developers/guides/customer/communities) | Community membership and access gates | | [Waitlist](/developers/guides/customer/waitlist) | Join and manage waitlists | --- ## Base URLs | Environment | URL | |---|---| | Production | `https://b.anny.co` | | Gov-Cloud | `https://b.anny.eu` | termsOfService: https://anny.co/terms-of-use x-logo: url: https://cdn.anny.co/cms/anny_logo_main_colour_blue_4865e76654.svg altText: anny logo href: https://anny.co servers: - url: https://b.anny.co description: Production - url: https://b.anny.eu description: Gov-Cloud security: [] tags: - name: Account Passes - name: Account Skills - name: Addresses - name: Availability - name: Booking Bundles - name: Booking Passes - name: Booking Quota Grants - name: Bookings - name: Communities - name: Community Accounts - name: Community Invites - name: Customer Accounts - name: Favorites - name: Orders - name: Organizations - name: Plan Subscriptions - name: Properties - name: Queues - name: Queue Tickets - name: Resources - name: Services - name: Waitlist paths: /api/v1/services/{service_slug}/add-ons: parameters: - schema: type: string name: service_slug in: path required: true get: tags: - Services summary: Get available add-ons for a given service operationId: get-services-record-add-ons parameters: - schema: type: string enum: - name in: query name: sort - name: filter[search] in: query schema: type: string - name: filter[name] in: query schema: type: string - schema: type: string in: query name: filter[description] - schema: type: string in: query name: filter[customer_notice] responses: '200': description: OK content: application/vnd.api+json: schema: type: object properties: data: type: array items: $ref: '#/components/schemas/add-ons.v1' examples: default: value: data: - type: add-ons id: '239' attributes: name: Vegan Food description: >-
