RESTful API Jobs

RESTful API stands for Representational State Transfer Application Programming Interface, a term coined by Roy Fielding in 2000. A RESTful API allows an application to communicate with other applications. It is based on the structure of a website, where the data and information are stored in the form of resources. RESTful APIs make use of these resources to provide a certain level of accessibility and data exchange between different systems. This makes web development more efficient, as resources can be accessed easily and quickly.

A RESTful API Developer is responsible for designing and developing APIs to facilitate communication between different applications. The Developer will use their existing skills in web development to create APIs that are secure and reliable, that can provide clients with the ability to access resources for different types of usage. The Developer will also ensure that the APIs are well documented so that any updates or changes to their backend programming environment don't cause any disruptions with existing communication workflows.
