Power Automate Showcase 3 – Practical Flow Hacks from the Community by Huseyin Korhan

Welcome to Power Automate Showcase #3 of my Power Automate series! These articles highlight real, hands-on solutions to everyday problems — often built by makers like YOU. Whether you're optimizing Teams workflows, tweaking SharePoint, or improving your app UI, there's something here for every Power Automator.  

In this edition, we're exploring three elegant solutions by Huseyin Korhan , a developer who’s been quietly sharing powerful examples that go far beyond the basics.  

Send Custom Notifications to Microsoft Teams  

The Problem: Native Power Automate Teams connectors are easy to use — but they’re also limited. You can’t add buttons, rich formatting, or send adaptive cards dynamically with fine-tuned logic.  

The Solution: Korhan shows how to send adaptive card-based notifications with dynamic inputs using the HTTP POST to Teams webhook method. This gives you full control over what your message looks like — including formatting, actions, and personalization.  

🛠️ Highlights:  

• Uses HTTP action with a pre-configured webhook URL  
• Sends JSON payloads with adaptive cards  
• Great for approval flows, alerts, or daily reports  

✅ Real-world scenarios:  

• Notify managers only if a project risk exceeds a threshold  
• Display formatted tables from Dataverse  
• Include quick-action buttons directly in Teams chat  

Hide or Show SharePoint List Columns via Flow  

The Problem: You’ve got a SharePoint list, but you want to show or hide certain fields based on the item’s status, role of the user, or stage in the workflow. SharePoint itself doesn’t support conditional column visibility directly.  

The Solution: This flow uses the SharePoint REST API in combination with the Send an HTTP request to SharePoint action in Power Automate to update view schema dynamically — hiding or showing columns on demand.  

🛠️ Highlights:  

• No manual editing of SharePoint views  
• REST API used to manipulate the View XML schema  
• Can be embedded into approval workflows or triggered on item update  

✅ Real-world scenarios:  

• Automatically simplify views for external users  
• Hide sensitive columns after form submission  
• Show specific financial fields only after approval  

Beautiful HTML Table Formatting for Emails  

The Problem: If you’ve ever used the Create HTML Table action in Power Automate, you know the output looks like 1997. No style, no clarity, and definitely not boss-approved.  

The Solution: This example shows how to create custom HTML tables with inline styles , colors, column widths, headers, and even conditional formatting — all sent via email or Teams.  

🛠️ Highlights:  

• Full control over <table> structure with inline CSS  
• Can be embedded in Send an Email (V2) or Adaptive Cards  
• Supports nested loops and conditionally styled rows  

✅ Real-world scenarios:  

• Send clean weekly reports from SharePoint or Dataverse  
• Replace Excel exports with readable tables  
• Embed well-formatted tables into Teams or Outlook alerts  

What’s Coming Next: Power Apps Attachments — the Pain Points  

If you’ve worked with Power Apps attachments , you already know the chaos they can cause:  

• Attachments disappearing after submission  
• Delegation issues when filtering for files  
• Problems with PATCH statements  
• Weird bugs in the attachments control when used in forms or galleries  

Korhan currently preparing an in-depth walkthrough and troubleshooting guide on these quirks — including workarounds, patterns, and performance advice. You’ll get code samples , test cases , and a few rage memes , too. 😅
