How to fetch Microsoft copilot chats

Hello,

Is there any API which allows to fetch the chat between a user and Microsoft copilot? I looked into graph API for teams, but it doesn't allow to do so.

For example:
I sent message to Microsoft copilot to summarize a word document for me (within Microsoft teams). It returns me the summarized version.

I want to fetch that conversation as one on one via API.

If there is no such support, can you please provide relevant links that mentions the same?

Thanks

    You can use the Copilot Activity Export API to retrieve interactions between a user and Microsoft Copilot across apps like Teams, Word, and Outlook.

    Official documentation

    GET https://graph.microsoft.com/v1.0/copilot/users/{userId}/interactionHistory/getAllEnterpriseInteraction

    Limitations of Microsoft Graph API for Teams Chat

    • The standard Graph API for Teams does not allow access to Copilot chats as regular one-on-one messages.
    • Copilot chats are not stored as typical Teams messages and are not accessible via chatMessage or channelMessage endpoints.
    • You cannot use Graph API to fetch Copilot chats unless you use the Copilot-specific APIs.

    Alternative: Copilot Chat API

    If you're building custom integrations, the Copilot Chat API allows you to initiate and continue conversations with Copilot programmatically.

    However:

    • It’s not meant for retrieving past chats.
    • It’s focused on real-time interaction, not history export.
