Merge is a Unified API platform designed to simplify the integration of various third-party software systems, such as HRISs, CRMs, accounting, and marketing automation software, through a single API. It addresses challenges in unifying HR data by offering a standardized schema that eliminates the need for multiple APIs and custom solutions, ensuring data consistency and accuracy across integrated systems. By supporting webhooks and customizable sync frequencies, Merge enhances performance and reduces costs while securing data through encryption and compliance with regulations like GDPR and HIPAA. The platform is scalable, accommodating growing data volumes and future system changes without extensive redevelopment. Merge's capabilities were demonstrated through a tutorial on creating an org chart by integrating employee data from BambooHR, BreatheHR, and Humaans, showcasing its potential for employee reporting and analytics while eliminating manual data entry and ensuring seamless data flow across HR systems.
