Question details
Developers need a method to pass external website information, such as a user's signed-in status, to a Microsoft Copilot conversation for personalized interactions.

- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- A developer is integrating Microsoft Copilot into an external website and wants to use the site's authentication context to customize the AI's responses based on specific user properties.
- Observed behavior
- The development environment requires a secure and officially supported framework to inject external authentication data and user properties directly into the Copilot chat session.
Ensure you have developer access to your external website's backend and the Microsoft Copilot configuration environment before attempting to implement custom authentication context.
Consult the Microsoft Copilot Q&A Community
Because passing external user properties involves secure authentication context, the best approach is to request tailored guidance from Copilot specialists on Microsoft Q&A.
Integrating external website data, such as a signed-in status, into a Copilot conversation is a highly specialized developer task. It requires properly configuring authentication tokens and handling data privacy.
Since implementation details vary based on your specific web framework and Microsoft environment, reaching out to the official developer community ensures you receive the most secure and up-to-date integration methods.
Open your web browser and navigate to the official Microsoft Q&A platform tailored for developer support.
Use the site's category filter or search bar to locate the dedicated 'Microsoft Copilot' section, which is monitored by specialized engineers.
Post a detailed question describing your external website's framework, the specific user properties you wish to pass, and ask for secure integration strategies.

Frequently Asked Questions
Can I pass custom variables to Microsoft Copilot from my website?
Yes, developers can pass custom variables such as user IDs or display names from an external website to Copilot. This typically involves defining global variables in Copilot Studio and passing them via the bot's embed code.
How do I securely pass a user's signed-in status to Copilot?
To securely pass a signed-in status, you should utilize external authentication context. This involves passing validated authentication tokens rather than raw user data, ensuring the integration adheres to modern privacy and security standards.
Why is my Copilot not recognizing the user properties I passed?
This can happen if the variables in Copilot are not configured to receive external values, or if there is a mismatch in the exact variable names. Verify your JavaScript embed code and ensure the data payload aligns with the parameters expected by Copilot.
