Question: How Do I Check My API Performance?

What is acceptable response time for web applications?

A one-second response time is generally the maximum acceptable limit, as users still likely won’t notice a delay.

Anything more than one second is problematic, and with a delay of around five or six seconds a user will typically leave the website or application entirely..

How do I check my REST API response time?

The Response class in rest assured offers a method getTime() which will return the response time. The response time is returned in milliseconds. However for some reason if rest assured can’t get the response time, it returns -1.

How does OAuth work in REST API?

Process. The authentication process, commonly known as the “OAuth dance”, works by getting the resource owner to grant access to their information on the resource, by authenticating a request token. This request token is used by the consumer to obtain an access token from the resource.

What are API metrics?

The most basic set of API metrics is operational. They measure API performance, such as the number of APIs, the number of API calls, CPU or memory usage. Operational metrics give an indication of the operational stability of an API platform.

What is API load testing?

It’s a way to check whether your application is robust enough to handle the load you want it to handle before your users find that out for you. API load testing is going through this process by simulating multiple users sending requests to your server at the same time.
