An API client is a development tool that makes it easier for producers and consumers to explore, test, and debug APIs.
Traditional approaches to calling an API require a significant amount of specialized knowledge; for instance, the API user must know a programming language, understand the API's framework and protocol, and be able to interpret the response.
This time-consuming process not only slows down API development and integration efforts, but also prevents people with less technical backgrounds from working with APIs.
API clients abstract away some of this complexity, lowering the barrier to entry for API-related work and enabling developers to stay focused on big-picture goals.
REST (Representational State Transfer) is an architectural style for building web services and APIs.
In a RESTful architecture, resources are identified by URIs (Uniform Resource Identifiers), and operations are performed on those resources using standard HTTP methods such as GET, POST, PUT, and DELETE.
An API gateway is a server that acts as an entry point for clients to access and interact with multiple microservices and backend systems.
API gateways are an important component of microservice-based architectures, as they provide a centralized point of control for many common tasks that would otherwise be performed by each individual microservice.
GraphQL is an open source query language for APIs that was created by Facebook in 2012.
With GraphQL, clients interact with a single endpoint and specify the exact data they need, without having to chain multiple requests together.
This approach reduces the number of round trips between the client and the server, which can improve performance—especially on slow or unreliable network connections.
✔️Enforce security rules on API definitions and requests
Postman API Security provides a set of default security rules, based on the OWASP “Top 10” for APIs, which will automatically surface common vulnerabilities and violations in your API landscape. blog.postman.com/introducing-ap…
✔️Customize security rules to fit your needs
Every organization is different, which is why Postman API Security enables teams to define and import custom rules according to Spectral guidelines.
API-first is an organizational strategy and development model in which APIs are prioritized to deliver maximum value to the business. In this model, applications are designed and built by composing private, partner, or public APIs. postman.com/api-first/
