Excerpt of article text...

Most modern Web APIs are designed to provide access to data and return it using the popular JSON format. However, APIs are capable of doing much more than that. In this article, you'll learn how to use Xojo to develop an API that generates barcodes and QRCodes.

Introduction

As developers, most of the Web APIs that we integrate with or develop involve retrieving, adding, updating, or removing data. These APIs are often referred to as "CRUD" APIs because they provide functions for creating, reading, updating, and deleting records in a database. And in most cases, these APIs return data as JSON-encoded text.

However, APIs can also be used to create a number of other types of responses. For example, there are APIs available that can be used to generate maps, charts, documents, and more.

In this article, I will show you how you can use Xojo, along with Aloe Express and the MBS Xojo Barcode Plugin, to create a simple API that generates both barcodes and QRCodes.
