Can we create a fully custom web application from full-scratch on ServiceNow instance?

[Aki18]

We need to create a fully custom web applications from full-scratch on ServiceNow instance, but how can we achieve this?
What we would like to do is to design custom UI/UX and to create some kind of custom web app that works like below:

1. Get necessary record data from ServiceNow by API.
2. Show them as a list in the way we designed.
3. Operate the list in various way we designed.

If it's possible, please let me know how to make it on ServiceNow instance.

Best Regards,
Aki

Hello @Aki18 ,

You can create custom tables, store data in the custom tables and build logics around the data in ServiceNow.

You will require an user account with necessary roles to create, update and retrieve records from the custom tables through REST API's.

Thanks!!

Hi @Aki8 , Yes, it is possible. you can explore an option to create a service portal for your web application.

For your UI/UX, either you can use OOB widgets if those fits  your requirement or create your own custom widgets.

If your requirement is to create web application outside ServiceNow, then you can use Table API to consume data from ServiceNow. If that is not enough then you can use Scripted REST API options for custom API's.

Hope this is helpful!

Web Design Services provides a wide range of tools and resources to support application development, including its own scripting language (GlideScript), a comprehensive development environment, and a developer community. Keep in mind that while Web Design Services makes it easier to develop custom applications, some level of technical expertise is still required, especially when it comes to scripting and integration with external systems.

Yes, you can create a fully custom web application from scratch on a ServiceNow instance. ServiceNow provides robust tools such as the App Engine Studio for low-code development, JavaScript-based scripting for complex functionalities, and the Service Portal or UI Builder for designing user-friendly interfaces.

You can also leverage its extensive integration capabilities with REST and SOAP APIs. Treat your project like any other software development endeavor by planning thoroughly, defining requirements, managing tasks, and testing rigorously. Additionally, the ServiceNow Community and available documentation are invaluable resources for guidance and support throughout your development process.
