A scalable and affordable solution that performs well and provides excellent technical support

If we publish API or GET requests, sometimes someone can do a POST request of the API. Such security violations are not visible in the product. Other solutions provide such security features. The product does not provide visibility into the security loopholes in the authentication and authorization mechanism. The product must improve its security features. It has protection capabilities, but it must provide better visibility on the dashboard. The dashboard must be improved a lot.

Solution simplifies web service testing with impressive speed and accessibility

It is very easy for me to use and I highly prefer it compared to SoapUI and other products for performing its job. It is more handy and faster. It has impacted us very nicely. Postman is used for free by us. I'm not sure if there might be a paid version for multiple users. It is a very good product used for development. It is easy to install, as well as to learn, particularly for new users, even if they are not developers. I taught my business analyst to use it. I just showed them once, and it was easy for them to understand. For example, I gave them the URL and request format and asked them to test independently. They were able to use it on their own and do their testing as well. It was a good experience, especially for generally smart people, like those we usually hire in our company. It is pretty easy to explain, and learning it is not complex.

Overview

The NGINX Plus API gateway authenticates API calls, routes requests to appropriate backends, applies rate limits to prevent overloading services and to mitigate volumetric attacks, offloads SSL/TLS traffic, and handles errors and exceptions. NGINX's API gateway takes all API requests from a client, determines which services are needed, and delivers the result in a high‑performance manner.

NGINX Plus API gateway is used to protect APIs with rate‑limiting policies, enforce specific request methods, and provide fine‑grained access control:

Ensures application backends are not overwhelmed by a problematic or malicious API clients through rate limits based on attribute of the request.
NGINX Plus allows only specific request methods for app services. For example, you can accept only the GET method to ensure that access to your inventory service is read‑only (just returns the inventory).
Controls access to specific resources using JSON Web Tokens (JWTs). For example, you can allow write access to a service for API clients with admin credentials, but only read access for clients with standard user credentials.

Postman's Tools Support Every Stage of the API Lifecycle. Through design, testing and full production, Postman is there for faster, easier API development - without the chaos.
