SOAP is Cvent’s original set of APIs. The tight integration of SOAP APIs into our legacy systems does not support newer product features. The Cvent REST API is our successor to SOAP and offers a modern approach to building web services that are more flexible, scalable, efficient, and integrate with the newest Cvent features.
REST API is a powerful tool for clients to access all their event-related data. Many customers have started to adopt the REST API in their integration strategy, but they also have legacy integrations that are still running on the SOAP API. As customers plan to migrate their integrations to the REST API, it can feel daunting.
