In the webinar "The ROI of Using APIs to Build Email and Scheduling Productivity Features," the significance of APIs in digital transformation was emphasized, with 84.5% of participants acknowledging their critical role. The discussion highlighted how COVID-19 increased demand for native email and calendar features across industries like healthcare, sales, recruiting, and real estate, as professionals needed secure and efficient scheduling solutions for telehealth, virtual meetings, and online interviews. The challenges of developing these features in-house were addressed, noting the complexity and time consumption involved in building API integrations from scratch. To overcome these hurdles, outsourcing to third-party vendors like Nylas was recommended, as it can significantly reduce development time and streamline integration with major providers. Nylas' API solutions have led to substantial ROI gains for its clients, such as Pipedrive, Clio, Lever, and Ceridian, by enhancing their offerings and attracting new subscribers, thus boosting revenue.
