An estimated 80% of organizations with APIs have some form of strategy in place, emphasizing the importance of a deliberate approach to API management. These organizations aren’t just adopting strategies arbitrarily; there’s a clear business benefit. Those with an API strategy experience 17% higher productivity compared to those without one – leading to the rapidly growing popularity of API gateways.

“The data underscores a compelling insight: having an API strategy, in any form, results in significantly better business outcomes than not having one at all.”

An API Gateway is a system used within businesses to oversee and direct the communication between multiple software applications and services. Whenever an application requires data or a specific operation from another service, it sends a request. The API Gateway processes this request, ensuring it adheres to established protocols and security measures. Once verified, the gateway routes the request to the appropriate service.
