Open API V2 — Introduction | ExpoPlatform Helpdesk

This is the client-facing reference for the ExpoPlatform Open API V2. It lets you programmatically create, read, update, and delete data within your event — participants, exhibitors, sessions, floor plan, products, news, notifications, and more.

Each section documents a specific API endpoint group, with a full parameter reference and practical how-to guides for the most common workflows.

Before diving in: Make sure you've read Understanding the ExpoPlatform Data Environment. It covers how environments and events relate, which fields are global vs local, cascade behaviour, and the universal rules (accepted image formats, account statuses, the send_email warning) that apply to every API call. That knowledge is assumed throughout this documentation.

Where to start

If you are integrating for the first time, the recommended reading order is:

Understanding the ExpoPlatform Data Environment — read this first
Confirm your Event ID — the Open API V2 does not include an event lookup endpoint. Please confirm your event_id with your assigned ExpoPlatform API Manager before starting your integration
API Technical Reference — authentication, base URL, request/response format
Accounts — register and manage participants
Exhibitors — register and manage exhibiting companies
Floor Plan — set up halls and stands if needed for session locations. Stands must be marked as conference-eligible (is_conference=true) before they can be assigned to sessions
Sessions — build your programme
