# How to Integrate External Web Applications

The following article shows the logicnet steps to integrate an external web-based application into your LogicNets application in the following ways:

* open in new browser tab
* open in existing browser tab (redirect) and provide back URL
* open in iFrame

A video demo and example project are available [here](/release-9/platform-documentation/advanced-topics/system-integration/external-web-applications-example.md) for download into your Designer workspace.

### Open in New Browser Tab

Add a button or HTML-node to your logicnet with script to open the external application in another browser tab.

### Open in Existing Browser Tab (redirect)

1. Compose back-URL ![](https://2802811211-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FdFhfexCjZ5JMhwGzzywq%2Fuploads%2Fgit-blob-0e4423f33c980c58b7bc6d87634839087ef1abee%2F7959a36e-4f34-4720-b8c9-6bdc5e0810b7.png?alt=media)
2. Add back-URL as query parameter to the external application URL

WARNING: LogicNets does not recommend use of iframes in general. iframes are considered as unsafe and therefore using them may potentially lead to integration issues, security breaches and forced changes to external applications

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://community-test.logicnets.com/release-9/platform-documentation/advanced-topics/system-integration/how-to-integrate-external-web-applications.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
