Power Automate is often used to create approval flows. Users are notified via emails but there is only one place where one can check and review all the approvals: https://emea.flow.microsoft.com/manage/environments/Default-{tenant-id}/approvals/received I’ve been working on a solution to bring this experience to Teams via SPFx. In this article, I present the way to tackle the challenge. Kudos to Marcin Wojciechowski, who gave me a few tips to make this possible. The code is available on my GitHub. Graph API? First of all, I would like to mention that I’ve found a beta Graph endpoint: /beta/me/approvals but it’s not documented and it doesn’t return any significant data. Anyway, you can find a powerusers forum thread where you will notice that people have been asking for that kind of API since 2017. Reverse engineering  While checking the network communication on the approvals site, I’ve found endpoints that are used for getting all active approvals and accepting/rejecting them. I’ve explored this endpoint with Postman and SPFx. I’ve got rid of redundant headers and found out that API doesn’t have a strict CORS policy which was an issue with other private Microsoft endpoints I explored. Till now, I used an authentication token copied from Chrome from the approvals site. So, That’s why I had to find a way to get the token and grant SPFx application permission to access the API. I started with decoding the token with jwt.io to find out to which resource it’s authenticating: appid: 6204c1d1-4712-4c46-a7d9-3ed63d992682 Using the app id, I’ve located the app among other enterprise applications at portal.azure.com: it’s Microsoft Flow Portal. Grant permissions To authenticate your SPFx application to flow service: Go to the portal.azure.com -> App registrations,Open the “SharePoint Online Client Extensibility Web Application Principal” app and select API permissions,Add new permission and switch tab to “APIs my organizati
