# Integration Fundamentals

This Module covers the basic use cases for integrating with external systems, using the Action Node **Web Request. Web Request** is used for integrations, and you may use it to push data to an external endpoint (POST/PUT requests) or get data from an external endpoint (GET request)**.**

The **Web Request** Action Node may be used both from Apps or from Services. E.g. you may have an App with a Button for looking up a company organization number from an external endpoint, or you may have a Service that runs nightly for fetching all new/modified customers from an external endpoint (and saves them). Both of these scenarios use the Web Request action node, and the technical setup is in general the same - regardless of whether the Web Request is triggered from an App or a Service.
