OnSite Solutions API

December 14, 2021


This API was retired as of October 31, 2021 and was replaced by our REST API. Please reach out to your Cvent account team or customer support if you need help transitioning.


With this API, you can read and write to the OnSite Solutions database. The API also gives you the ability to create events and add registrants, sessions, and exhibitors. During or after an event, you can also use the API to access information that is collected onsite, such as check-in data and leads collected from LeadCapture.

The API is currently designed for event planners. It currently doesn’t support individual exhibitors.

Getting Started

To start using the API, you must first request an API Key from your Account Manager. Once you have your API key, you can use it to access our system. The links in each section will take you to Swagger where you can find continually updated code.
