How to Connect ChatGPT with Power Automate (2025)

“Imagine your workflows not just automated… but intelligent.”

That’s exactly what happens when you connect ChatGPT with Power Automate.In 2025, businesses and creators are moving beyond basic automation — they’re building AI-powered workflows that think, respond, and adapt automatically.

If you’ve ever wanted your emails to write themselves, your Excel data to summarize automatically, or your support replies to be handled by AI — this tutorial will show you how to integrate ChatGPT with Power Automate step-by-step.

Why Combine ChatGPT and Power Automate?

Microsoft Power Automate Desktop already helps you automate repetitive tasks like sending emails, organizing files, or scraping data from websites.

But when you add ChatGPT’s intelligence, your flows become smarter.Here’s what’s possible:

Generate instant AI-based replies to customer messages.
Summarize Excel or SharePoint data automatically.
Create AI-powered reports or insights on demand.
Write professional emails and proposals with one click.
Automate workflows using OpenAI API and Power Automate HTTP connectors.

This blend of AI workflow automation tools lets you move from simple automation to true intelligent automation.

Step-by-Step: How to Connect ChatGPT with Power Automate

Let’s break it down clearly so even beginners can follow along.

Step 1: Get Your OpenAI API Key

To connect ChatGPT, you’ll need an OpenAI API key.

Visit https://platform.openai.com.
Sign up or log in.
Go to your API Keys section and copy your secret key.

This API key allows Power Automate to send prompts and receive ChatGPT’s responses.

Step 2: Open Power Automate and Create a New Flow

Open Power Automate Desktop or Power Automate Cloud (flow.microsoft.com).
Click + Create → Instant cloud flow.
Choose a trigger (for example, When an email arrives, When a form is submitted, etc.).

You’re now ready to build your ChatGPT Power Automate integration.

Step 3: Add an HTTP Request Action

This is where the magic happens.

Add a new step: “HTTP” (Premium connector).
Choose POST method.
In the URL field, enter: https://api.openai.com/v1/chat/completions
Under Headers, add: Content-Type: application/json Authorization: Bearer YOUR_API_KEY
In the Body, paste: { "model": "gpt-3.5-turbo", "messages": [{"role": "user", "content": "Summarize this email content"}] }

This sends a prompt directly to ChatGPT via Power Automate HTTP request.

Configure it as follows:

Method: POST  
URL: https://api.openai.com/v1/chat/completions  
Headers:  
  Content-Type: application/json  
  Authorization: Bearer YOUR_API_KEY  
Body:
{
  "model": "gpt-4-turbo",
  "messages": [{"role": "user", "content": "Write a summary of the latest email"}]
}

This sends a request to OpenAI and receives a smart response.

✅ This is the foundation of Power Automate OpenAI integration.

Step 4: Use Dynamic Inputs in Your Flow

Let’s make it smarter.Instead of static text, use dynamic content — like email body, form data, or document content.

Example:If a new email arrives → extract the message → send it to ChatGPT → get a summarized reply → auto-send a response via Outlook.

This kind of smart workflow automation with ChatGPT saves hours every week.

Step 5: Add Output Actions

Once ChatGPT responds, you can:

Send the response via Outlook.
Save it in Excel or SharePoint.
Post it in Teams or Slack.
Trigger another AI-powered flow automatically.

You can even use Power Automate AI Builder to classify or translate ChatGPT responses before using them in your workflow.

Real-World Examples of ChatGPT + Power Automate Integration

Here are some powerful ChatGPT automation ideas for 2025:

Generate smarter analytics from everyday data.

By connecting OpenAI API with Power Automate, even small teams can achieve enterprise-level automation — affordably.

This is the future of AI enhanced productivity tools — combining logic with creativity.

Advanced Setup: Create a Custom Connector for ChatGPT

If you want cleaner integration, create a custom connector in Power Automate.

Go to Data → Custom Connectors → New Custom Connector.
Define the OpenAI endpoint and parameters.
Map “Prompt” input and “Response” output fields.
Save and use it across multiple flows.

Now you can trigger ChatGPT responses in Power Automate with a single action — no more HTTP setup each time.

Step-by-Step Recap

1️⃣ Get your OpenAI API key
2️⃣ Create a flow in Power Automate
3️⃣ Add HTTP request to connect ChatGPT

Pro Tips for Smarter Automation

1: Use conditional logic — only call ChatGPT when needed (e.g., when an email contains “urgent” or “feedback”). 2: Add delay and retry policies for stable API calls.
3: Combine ChatGPT with Azure OpenAI for enterprise-level security.
4: Create reusable prompt templates like “Summarize this,” “Translate this,” or “Generate reply for…”.
5: Monitor your flow history — use success/failure tracking to optimize your AI calls.
