The State of SaaS APIs 2024

The inaugural "State of SaaS APIs 2024" report provides a comprehensive analysis of API implementation and design within the rapidly evolving Software as a Service (SaaS) industry, which increasingly relies on APIs to facilitate data sharing between applications. As SaaS applications grow in complexity, APIs have become more specialized, with examples like HRIS APIs for payroll and CRM APIs for sales intelligence. The report delves into key aspects of authentication, such as the widespread adoption of OAuth 2 with the 3-legged authorization flow, and highlights the challenges developers face due to the limited support for native webhooks, requiring them to create their own polling strategies. Drawing on over two decades of experience in API integration software development, the report offers valuable insights into current trends and practices, aiding in informed decision-making for API implementation.
