Feb 25, 2024 · API throttling adjusts the pace at which applications can make API calls, ensuring that the system remains stable and functional under varying loads. It's like having a dynamic speed limit for data traffic, slowing things down just enough to keep the flow steady and prevent crashes.

When a software engineer builds an API, he or she provisions a certain amount of servers to satisfy the expected incoming demand. For instance, If I have a very unpopular system, I may only allocate a couple servers to handle and process incoming traffic. Conversely, if I have a very popular API, I will go ahead and configure a large amount of serv...
Applications can use a variety of techniques to rate limit their clients. The basic outcome from the client side is the same though: if you exceed a certain number of requests per time window, your requests will be rejected and the API will throw you a ThrottlingException. Throttling exceptions indicate what you would expect – you’re either calling...
The Token Bucket Algorithm has two major components, burst and refill (sometimes called sustain). We define them below. 1. Burst – Burst corresponds to the number of ‘Tokens’ that are available for a client. The Tokens are consumed every time a request comes in. In this example, imagine that a token is a 1:1 mapping to a drop of water in a bucket. ...
From the server perspective, Rate Limiting means that you need to either use existing rate limiting features in web servers, or build your own to control traffic. For example, here’s an example from NGINX showing a rate limited API by client IP address at a rate of 1 request / second: Using IP address is a bit ill advised here since its very easy f...
If you’re a Client, or a user of a rate limited API, there are some important things to be aware of. Most importantly, you as the client need to be aware of your rate limits. This helps you design your system in such a way that you won’t exceed the rates provisioned by your resource server. Secondly, its important to implement a robust retry policy...
Its important to know what Rate Limiting / Throttling is from both the client and the server perspective. If you’re a developer using an open source API, I guarantee you that you will at some point be facing the dreaded ThrottlingException or RateLimitedExceedExceptionfrom these APIs. Its important to know how to handle them in any case. If you’re ...
Mar 20, 2024 · API throttling is an essential process that API developers need to limit how often users can access their API. With API throttling, you can prevent overloads, thus ensuring a smooth API performance for all users, as well as protecting the API from denial-of-service attacks!
API throttling is an elegant solution that helps organizations to ensure fair use of their APIs. API 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.
Aug 5, 2024 · Rate limiting is a technique for controlling the amount of incoming and outgoing traffic on an API by setting a predefined limit on how many requests an API user can make within a given timeframe.
Mar 5, 2024 · Microsoft is implementing API throttling to allow more consistent performance within a time span for partners calling the Partner Center APIs. Throttling limits the number of requests to a service in a time span to prevent overuse of resources.
Mar 8, 2023 · API throttling is a type of rate limiting that is used to control the amount of traffic that an API can handle. It is a way of limiting the number of requests that the API will accept in a given period of time.
