Overview of this book

Organizations are moving their applications, data, and processes to the cloud to reduce application costs, effort, and maintenance. However, adopting new technology poses challenges for developers, solutions architects, and designers due to a lack of knowledge and appropriate practical training resources. This book helps you get to grips with Oracle Visual Builder (VB) and enables you to quickly develop web and mobile applications and deploy them to production without hassle. This book will provide you with a solid understanding of VB so that you can adopt it at a faster pace and start building applications right away. After working with real-time examples to learn about VB, you'll discover how to design, develop, and deploy web and mobile applications quickly. You'll cover all the VB components in-depth, including web and mobile application development, business objects, and service connections. In order to use all these components, you'll also explore best practices, security, and recommendations, which are well explained within the chapters. Finally, this book will help you gain the knowledge you need to enhance the performance of an application before deploying it to production. By the end of this book, you will be able to work independently and deploy your VB applications efficiently and with confidence.

Tracking REST calls

In this section, we'll describe how to track REST calls. Since the data communication in Visual Builder applications happens via REST APIs, it's very important to track the REST calls. When you call any Business Objects or any external REST APIs, a request is made to the server to push or pull data depending on the REST call. Sometimes you may need to track the REST calls end to end to debug the REST API issues.

For example, if the VB application calls any external REST API to push data into the external application but somehow all the records could not be updated successfully in the external application, as a developer, it's your duty to debug the VB application to check where the problem is located.

In order to debug such issues in VB, open the browser development console, move to the Network tab, and replicate the issue. Click on the REST API name that you want to track and view the complete REST API details from request to response.
