You can create SuiteScript Server Page (SSP) applications to add a custom application to your web store. SSP applications are made up of a front-end page that executes server side SuiteScript.
SSP applications can be written in both SuiteScript 1.0 and SuiteScript 2.0.
See the following topics for more information about SSP applications:
SSP Application Overview – This topic gives you a broader understanding of SSP Applications. It discusses the different components of SSP Applications, compares SSP application capabilities with Suitelets, RESTlets, and Scriptable Cart, and describes the ways in which SSP applications differ based on the version of SuiteScript in which they are written.
Create and Use SSP Applications – The topics here teach you how to create an SSP Application, including how to create an SSP application record. This section also contains code samples for SSP Applications in both SuiteScript 1.0 and SuiteScript 2.0.
Integration with Third Party Checkout Providers – you can integrate your SSP Application with third party providers such as Paypal express. This topic teaches how to create the request handlers and call them from your SSP Application.
