# Building a RESTful CRUD Web Service

In this guide, we will use Integration Gateway to create custom web service endpoints and its vault functionality as an underlying data store for retrieving, adding, updating, and deleting data when these endpoints are executed.

To help you follow this guide, you can download the JSON export of the integrations that are setup here and import the file into your own Integration Gateway environment.
