Involver launched its Engagement Optimization API last week (read the official release here). Partners are utilizing the API to "optimize their ad spend on social in the way they've been doing across the web for a long time." Although advertising across social networks has been deployed for quite some time, advertisers have had limited tools to track engagement. Facebook Insights is probably most commonly used to analyze social data. When users have required deeper analysis, the advertisers were forced to use highly custom integrations.
eZ-Xpo, virtual tradeshow management platform, announced the release of the eZ-Xpo Open Event Management API. The API integrates with third party applications such as Eventbrite, Cvent, Etouches, Amiando, and many more. Integration with the API allows third party apps to include management planning, registration, and promotion for events.
