API Integration

The influx of software applications and the rising demand for customized products and services call for an unobstructed flow of data. APIs serve as a medium to exchange information between systems and applications. Due to the migration of business services to the cloud, API integration is gaining momentum. Instead of having internal IT server and staff, APIs stitch together applications available in the internet for quicker time to market and reduced costs.

While APIs transfer data between devices and the cloud, the data is protected by HTTPS while in transit. The data resting on the client or server is also encrypted. Another way to reduce the possibilities of data breach is developer registration. API keys, unique to every developer, are used to keep track of the devices using the APIs. Random tokens that expire after a given time are also a great way to ensure security.

Developers find REST (Representational State Transfer) APIs as more agile. Many cloud service providers prefer them because they provide lightweight communication between producers and customers. However, they also come with a set of disadvantages. A number of security concerns arise due to the lesser overall consistency in app updates. An effective way to secure REST is through network standards that assign IP addresses in which components are deployed.

Another API integration challenge is testing as it can be extremely difficult if performed by conventional methods. The implementation can collide with cloud resource mapping. The successful testing of APIs in the cloud is based on “abstraction”, a technique that exposes the features without exposing the implementation. By including component scaling and resource allocation features, it enables a test plan to include cloud-related elements without disturbing the cloud quality of the experience.

REST APIs are scaling high in their implementation by assisting convenient integration and possessing resilience and scalability in cloud applications. They are an affordable and powerful way to use pre-existing applications in the cloud to drive your business.

REST API

REST API stands for Representational State Transfer Application Program Interface, and relies on stateless, client-server and cacheable communications protocol. As an architecture style for designing networked applications, it uses a simple HTTP protocol to make calls between machines. Today, there are no applications or projects without REST API. The World Wide Web itself can be viewed as a rest-based design since it is based on HTTP.

REST API Features:

  • Stateless Client/Server Protocol. This means the client/server do not need to remember any previous state to satisfy it because each HTTP contains all necessary information. The client can run the same response to the same HTTP requests in the future.
  • Data transactions. There are four of them in any HTTP specification and REST system: POST (create), GET (read and consult), PUT (edit) and DELETE.

  • Manipulated from the URL. Objects in REST are manipulated from the URL, which is the sole identifier for each resource in the system. The URL allows access to information in order to edit or delete it, or share the exact location to third parties.
  • Uniform Interface. In order to transfer data, the REST system applies specific data transactions on the resources, making it easier to get a uniform interface that organizes the process with information.
  • Layer System. The REST API has a hierarchical architecture between components, wherein every layer has specific functions in the system.
  • Use of Hypermedia. An extension of hypertext, hypermedia an app development interface’s capacity to provide adequate links in order to run specific actions on data.

Is REST API a winning strategy? Here are three main advantages of using REST for development:

  • Separation between client and server
  • Dependency on type of platform or languages
  • Visibility, scalability, reliability

Separation from the server and data storage improves portability of interface to other types of platforms. It also increases visibility, scalability and reliability, making the apps more flexible to work with. Furthermore, it adapts to the syntax or platforms used. You can have PHP, Java, Node.js or Python servers.

Figuring out a winning API strategy is a great challenge for most companies. First, they need to develop the requirements to start building the actual software. Three or more teams are needed to develop a REST API project.

The modern enterprise needs hundreds to thousands of mobile applications, so the API building process goes on for over a few years with various contractors, consultants and developers. That’s why many companies are running hundreds of internal APIs that lack management, and are hard to discover and use by their partners, existing apps and internal developers.
