Access to Preview APIs

Matt Anderson 20 Reputation points

Hello Everyone,

I am a developer working for a very fast growing sales company. I am in the process of building an app to track marketing events using Power Automate and the Approvals connector. However, I have encountered some limitations that I believe the upcoming Teams Approval Graph API could help resolve. I noticed that the API is currently in preview, as listed on the Microsoft 365 roadmap ( I am eager to access this preview to expedite the development of the app, but I have not been able to locate any documentation on how to do so. I understand that it is expected to be generally available in May, but I would like to implement the app as soon as possible. Could anyone provide guidance on how to access the preview or point me in the direction of relevant documentation? Additionally, if there are any contacts or resources for accessing other preview APIs, I would greatly appreciate it. Thank you very much!

    Access to preview APIs is generally restricted to developers who are part of the Microsoft Developer Program or the Microsoft 365 Developer Program. These programs offer early access to APIs, documentation, and other resources for developers who are building solutions for the Microsoft platform.

    To gain access to the Teams Approval Graph API preview, you can follow these steps:

    Join the Microsoft 365 Developer Program: This program provides access to a range of developer resources, including documentation, samples, and previews of upcoming APIs. You can sign up for the program at

    Join the Microsoft Teams Developer Preview program: This program provides access to preview versions of Teams APIs, including the Teams Approval Graph API. You can sign up for the program at

    Review the Teams Approval Graph API documentation: Once you have access to the preview program, you can review the documentation for the Teams Approval Graph API at

    Keep in mind that preview APIs are subject to change, and any solutions built using preview APIs may need to be updated once the API is generally available. However, accessing preview APIs can help expedite the development process and ensure that your app is ready when the API is released.

    As for other preview APIs, you can check the Microsoft 365 Developer Program website or the Microsoft 365 roadmap for information on upcoming APIs and previews.
