# Introduction

This solution contains scripts to generate technical documentation for <u>Azure Logic Apps</u> and <u>Power Automate Flows</u>. It uses PowerShell to retrieve the Logic App or PowerAutomate Flow and creates a Markdown file with the flow in a Mermaid Diagram and tables of the actions and connections used in the flow.

## Support

This project uses GitHub Issues to track bugs and feature requests.
Please search the existing issues before filing new issues to avoid duplicates.

- For new issues, file your bug or feature request as a new [issue](https://github.com/stefanstranger/logicappdocs/issues).
  - If you can please add the Logic App Code (json content), cleared with any sensitive information to the issue if possible.
- For help, discussion, and support questions about using this project, join or start a [discussion](https://github.com/stefanstranger/logicappdocs/discussions).

Support for this project is limited to the resources listed above.

## Getting Started

Clone the repository and run the script. The script will prompt you for the parameters. It will then create a Markdown file in the directory you provided when running the script.

```powershell
# Clone the repository
git clone https://github.com/stefanstranger/logicappdocs.git
```

## Run the New-LogicAppDoc.ps1 PowerShell script to create the Markdown file for an Azure Logic App

Navigate to the folder where you have cloned the repository and run the New-LogicAppDoc.ps1 script.

```powershell
# Authenticate to Azure where the Azure Logic App is located
Login-AzAccount -SubscriptionId <SubscriptionId>

# Run the script
# Example:
#  .\src\New-LogicAppDoc.ps1 -SubscriptionId 'dfc1f10c-a847-4250-bde8-93c3d6c53ea0' -ResourceGroupName 'jiraintegration-demo-rg' -LogicAppName 'logic-jiraintegration-demo' -OutputPath 'c:\temp' 
.\src\New-LogicAppDoc.ps1 -SubscriptionId <SubscriptionId> -ResourceGroupName <ResourceGroupName> -LogicAppName <LogicAppName> -OutputPath <OutputDirectory>
```

## Run the New-PowerAutomateDoc.ps1 PowerShell script to create the Markdown file for a Power Automate Flow

Navigate to the folder where you have cloned the repository and run the New-PowerAutomateDoc.ps1 script.

To retrieve the Power Automate Environment Id, you can login to your Power Automate Portal in your browser via https://make.preview.powerautomate.com/ and copy the environment id from the URL.

```powershell
# Run the script
# Example:
#  .\src\New-PowerAutomateDoc.ps1 -EnvironmentName '839abcd7-59ab-4243-97ec-a5b8fcc104e4' -PowerAutomateName 'Notify of Canceled Meetings'
.\src\New-PowerAutomateDoc.ps1 -EnvironmentName <Power Automate Environment Id> -PowerAutomateName <Power Automate Flow Name>
```

## Open the Markdown file

You can open the Markdown file in Visual Studio Code or any other Markdown editor.

Go to the directory where you have saved the Markdown file (OutputPath) and open the Markdown file created.
