If a new request comes when the queue is already full, the request is discarded. At regular intervals, this algorithm removes a request from the front of the queue and processes it. When a new API call/ request is received, it is added to the end of the queue. This algorithm uses a first-in, first-out (FIFO) queue to hold the incoming requests. What Are the Major API Throttling Algorithms? Leaky Bucket API Throttling Algorithm The user will have to wait for a pre-agreed time period, or pay to make any more API calls.
If the request exceeds the limit, the API returns an error response to the user. If the request is within limits, the API performs as usual and completes the user’s task. The API throttling logic checks if the current request exceeds the allowed number of API calls. A client/user calls an API that interfaces with a web service or application. While there are various algorithms for API throttling, here are the basic steps in any API throttling algorithm: As the number of online users increases, businesses need to implement API throttling mechanisms to ensure fair usage, data security, and prevent malicious attacks. API throttling is an elegant solution that helps organizations to ensure fair use of their APIs.ĪPI throttling also helps to fight back denial of service (DoS) attack, where a malicious user sends enormous volumes of requests to bring down a website or a mobile application. As a result, users with better connections or faster interfaces might get a better experience than others. As the number of users increases, the websites or the mobile application starts showing the signs of performance degradation. APIs help the users of a website or mobile applications fulfil their tasks. Why do Businesses Need API Throttling?ĪPIs are one of the biggest assets of organizations. Then it uses APIs to fetch the flight information from the GDS (Global Distribution system) like Sabre or Amadeus. The OTA website collects information from the user including origin, destination, and date of travel. A Real-Life Example of API Throttling in BusinessĪssume that a person is searching for a flight through an OTA (online travel agency)site. Organizations use API throttling with various goals, such as security, scalability, performance, monetization, authentication, and availability. #BEING THROTTLED MEANING SOFTWARE#
This user could be a human or another software application. This API interacts with the web server of the social media application and performs the action of posting. For example, when a user clicks the post button on social media, the button click triggers an API call. An application programming interface (API) functions as a gateway between a user and a software application.
