Question details

The user is seeking guidance on how to integrate a custom Copilot into a website using a token endpoint rather than a standard iframe, and needs to know the correct channels to request development assistance.

How to Connect a Custom Copilot to a Website with a Token Endpoint
Product
Microsoft Copilot
Device & OS
not provided
Scenario
Developing a custom web application that requires authenticating and integrating Microsoft Copilot seamlessly via endpoints.
Observed behavior
The standard Microsoft 365 community does not have sufficient resources or knowledge to answer advanced token-endpoint integration queries.
Before you start

Ensure you have a clear outline of your website's backend architecture and a basic understanding of your custom authentication flow before seeking development support.

Solution 1Recommended

Request Assistance in Microsoft Q&A for Office Development

Because token endpoints and custom integrations involve web development, you should direct your query to the specialized Microsoft developer community rather than general end-user forums.

The general Microsoft 365 community forums are primarily aimed at end-users and basic administration. They have limited knowledge of complex iframe and token-endpoint implementations. To get accurate, technical guidance, you must use Microsoft's developer-focused Q&A platform.

1
Navigate to Microsoft Q&A

Open your web browser and go to the official Microsoft Q&A portal, which is dedicated to technical and developer support.

2
Select the Appropriate Tag

Click on 'Ask a question' and ensure you add the 'Office Development' tag to your post. This routes your question to engineers and developers familiar with custom Copilot integrations.

3
Provide Integration Details

In your question body, explicitly include your authentication flow, the specific token endpoint design you are attempting to use, and a detailed description of the desired website behavior.

Frequently Asked Questions

Why shouldn't I ask about Copilot token endpoints in standard Microsoft 365 forums?

Standard Microsoft 365 forums are geared toward end-user functionality and basic troubleshooting. Implementing custom token endpoints requires specialized web development expertise that is best addressed by software engineers on the Microsoft Q&A platform under the Office Development tag.

What is the difference between using an iframe and a token endpoint for Copilot?

An iframe is a simpler method to embed Copilot visually on a webpage, but it relies on external handling of sessions. A token endpoint allows for deeper backend integration, giving you full control over custom authentication flows and seamless data exchange between your server and Copilot.

What details are crucial when posting my development question on Microsoft Q&A?

To get a helpful response, you should include your current authentication flow framework (e.g., OAuth2), your endpoint URL structure, any specific error codes you are encountering, and a step-by-step description of what the integration is supposed to achieve on your website.
