Events App —
API Reference.

Overview

The Events app stores event data in two HubSpot custom CRM objects: events and event_registrations. The worksby.design API provides endpoints for listing events, managing registrations, and checking attendees in. Events themselves are created and edited directly in HubSpot CRM (not via this API) — see Managing events below.

Base URL: https://api.worksby.design/apps/events/

All responses are JSON. Successful responses include "success": true. Errors include "error": "<message>" and an appropriate HTTP status code.

Authentication

All endpoints except GET /license-status require the portal to have the Events app installed and a valid active license. Authentication is handled automatically — no API key is passed by the caller.

Every request must include portalId — the numeric HubSpot portal ID. For GET requests pass it as a query parameter. For POST requests include it in the JSON body.

The server validates that the portal has completed the OAuth install flow and holds a stored access token. If not, the endpoint returns 403 with { "error": "Portal <id> not authorised for events" }. If the license has expired it returns 403 with { "code": "LICENSE_INACTIVE" }.

Custom Object — events

Created automatically on first install. The name property is unique and acts as the primary identifier across all API calls and navigation links. Object type name: events. The numeric objectTypeId is portal-specific and resolved by the backend at runtime — callers never need it.

Custom Object — event_registrations

One record per attendee per event. Created by create-registration. Each registration is associated to its event and (optionally) to a HubSpot contact.

Associations

Three association labels are created automatically on install. Label names are stable contracts — the backend resolves portal-specific numeric type IDs at runtime by matching on the label name. Do not rename these labels in HubSpot.

Creating and Managing Events

Events are created and edited directly via the HubSpot CRM API — this worksby.design API does not expose a create/update event endpoint. Use the standard HubSpot /crm/v3/objects/{objectTypeId} endpoints with the events custom object.

Resolving the objectTypeId

HubSpot assigns a different numeric objectTypeId to the events custom object on each portal. To resolve it, fetch all schemas and find the one whose name field equals "events":

GET https://api.hubapi.com/crm/v3/schemas
Authorization: Bearer {access_token}

// In the response, find:
results.find(s => s.name === 'events').objectTypeId
// → e.g. "2-12345678"

Creating an event

Once you have the objectTypeId, create an event with a POST to /crm/v3/objects/{objectTypeId}:

POST https://api.hubapi.com/crm/v3/objects/{objectTypeId}
Authorization: Bearer {access_token}
Content-Type: application/json

{
  "properties": {
    "name": "Monthly Member Webinar",
    "url_slug": "monthly-member-webinar",
    "description": "Our regular online gathering for members.",
    "meta_description": "Free monthly online webinar — live panel and open Q&A.",
    "highlights": "Live panel, member updates, exclusive content.",
    "event_type": "webinar",
    "event_status": "published",
    "start_datetime": "2026-07-15T14:00:00.000Z",
    "end_datetime": "2026-07-15T16:00:00.000Z",
    "is_online": "true",
    "location_name": "Online via Microsoft Teams",
    "price_amount": "0",
    "price_currency": "EUR",
    "capacity_total": "500",
    "capacity_current": "0",
    "features": "recording",
    "registration_mode": "form",
    "image_featured": "https://images.unsplash.com/photo-...",
    "image_thumbnail": "https://images.unsplash.com/photo-..."
  }
}

Required properties for a visible event

At minimum, set these properties for an event to appear in fetch-events results:

• name — must be unique; this is the event identifier
• event_status: "published" — draft and cancelled events are excluded
• start_datetime — must be in the future (unless upcomingOnly: false)

Updating an event

PATCH https://api.hubapi.com/crm/v3/objects/{objectTypeId}/{eventId}
Authorization: Bearer {access_token}
Content-Type: application/json

{
  "properties": {
    "event_status": "cancelled"
  }
}
