API development - At our web development company



If your company uses technical solutions such as SOA or monolithic systems, you should consider replacing them with flexible APIs. Modern software development based on microservices and containers use APIs as an innovative solution to reduce the complexity of their entire architectures, as only an API interface can enable collaboration between the individual application units.

To give you an overview of our work, we explain the most important aspects of API development below.

What is an API interface?

Application Programming Interfaces (APIs) are the “bridge” between applications, created to overcome barriers within or between companies. These APIs consist of several tools, definitions and protocols for developing and integrating application software. If two or more applications are meant to access the same content, data and resources, the communication interface between them must work flawlessly.

In addition, API interfaces enable the automation of complicated and mostly manually executed processes. You can combine the advantages of different applications and thus get the best out of both programs for the end user. A mobile app, for example, can access your ERP system via an API interface and make the work of your field staff much easier.


Functionality of an API interface

There are three different API approaches: Private API, Partner API, and Public API. As the names already suggest, each approach is responsible for a specific area. The Private API represents the internal interface, the Partner API is responsible for communication with business partners and the Public API is publicly available and enables the link between two applications. An example of a public API would be the link between the Alexa voice control device and any other device that is to be connected to it.

At Pacific Codeline, we typically rely on REST APIs. REST stands for Representational State Transfer. The REST approach simplifies the development of interfaces enormously because it is an architectural design with fewer specifications than a comparatively complex SOAP-based interface. While SOAP (Simple Object Access Protocol) standardizes the communication between applications by providing numerous specifications, REST is limited to only six points. This gives developers the freedom to implement API interfaces quickly and easily.

What are the advantages of APIs?

Fast release of data and resources

from existing applications

Complicated tasks can be automated

Manual activity between applications is eliminated

Combine advantages of two different applications

Applications can communicate with each other

Simplified development of new applications

by autonomous systems with standardized interface

New sales channels through Public APIs

public interface possible

Entrepreneurial advantage

Modern API interfaces offer a company nearly infinite technical possibilities and competitive advantages. Smooth communication between individual programs is standard, but the development and rapid implementation of a new application today can turn the entire market on its head.

This is how it works

The challenge of developing APIs

The integration of legacy systems is a major challenge that we have learned to master through our experience with the many different technologies, clients and custom software solutions our development team has worked on. Problems often arise when those legacy systems cannot operate in the typical request and response mode, or performance is insufficient because the legacy system cannot handle several hundred requests per minute. Each of these situations is unique depending on the respective backend system, so our team takes the time to analyze and understand what system we are working with, where the issues are and what the best solution to those issues is.
