Though, more connections also entail certain difficulties during the integration development process. That’s why you need to be more aware of developing such integrations to avoid the pitfalls.

In this article, you will discover some popular shopping cart REST APIs and a unified API to connect to various eCommerce APIs at once.

What is a REST API?

A REST API (Representational State Transfer Application Programming Interface) is a web API that conforms to the REST architectural style constraints and allows to interact with RESTful web services.

REST APIs perform standard database functions via HTTP requests, such as creating, reading, updating, and deleting data within a resource. For instance, the HTTP GET method is used to retrieve data, the POST method is used to create one, the PUT method is used to update data, and the DELETE method is used to delete one. All standard HTTP methods can be used in API calls.

Information can be sent to clients in various formats, such as JavaScript Object Notation (JSON), HTML, XLT, Python, PHP, or plain text. JSON is the most widely used file format because it is both human- and machine-readable and language-agnostic.

API integration involves the following processes: onboarding, exploration, education, authentication, code samples, testing, monitoring, and sandboxing.
