Merge's approach to API management focuses on optimizing request efficiency and handling throttling policies to prevent errors and service interruptions. By using best practices such as reviewing API documentation to understand throttling methods, making efficient API calls, establishing custom throttling mechanisms like the Token Bucket Algorithm, and implementing caching and webhooks, API users can enhance data retrieval and minimize unnecessary requests. The Merge platform offers a unified API solution that simplifies integration by allowing users to manage multiple third-party connections through a single interface, thus streamlining the process of handling diverse API throttling policies. Jon Gitlin, the Senior Content Marketing Manager at Merge, highlights the platform's ability to alleviate the complexity of managing numerous HR integrations by centralizing them within its system.
