Get Pre-Image & Post-Image in Power Automate – No Plugin Needed!

 

🔍 No-Code, Low-Code Solution: Get Pre-Image & Post-Image in Power Automate – No Plugin Needed! 🚀

Want to capture the pre-image and post-image of a record in Power Automate? Here’s a simple no-code, low-code approach—no plugins required!

🛠 Steps to Set Up

1️⃣ Create a Power Automate Flow

• Use an HTTP Trigger to start the flow.
• 
  
  
  

2️⃣ Register a Webhook in Plugin Registration Tool

• Open the Plugin Registration Tool (I'm using XRMToolBox)
• Register a new webhook.
• 
  
  

3️⃣ Understand Flow URL & Apply to Webhook:

• Flow URL: 
• https://prod-1.../triggers/manual/paths/invoke?api-version=2016-06-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=bM1iAOcxcxYPRWp4qZyE

• Base URL:
• https://prod-1.../triggers/manual/paths/invoke

• Query Parameters:
• api-version = 2016-06-01
• sp = /triggers/manual/run (replace %2F with /)
• sv = 1.0
• sig = bM1iAOxxxRWp4qZyE
• 
  
• 

• Register Webhook Step and Image (Pre/Post Image same like plugin)
• 
  
  

 🎯How It Works

• Updating the Contact First Name:
• 

• When a contact is updated, the webhook triggers and sends a JSON request to the Power Automate flow.
• 
  
  
  

🔍 Extracting Pre-Image Data

• Go to Output, then click Show Raw Output.
• Access the JSON response.

• Target Object contains the updated values, while the Pre-Image Object holds the previous values.
• 
  
  
• Pre-Image Object
•
