Im working on a small project in my company where I'm using Outlook REST APIs. https://learn.microsoft.com/en-us/outlook/rest/get-started
So far so good.
The application is also registered in Microsoft Azure Active Directory. As explained here: https://learn.microsoft.com/en-us/graph/tutorials/angular?context=outlook%2Fcontext
Our application is permanently running and needs to get data every like 1 minute. This causes a lot of requests.
So are there any costs regarding Microsoft Api that I should know about. Or is the Calendar Api completely free. Didn't find any helpful information out there so far.
Thanks in advance for any help.
Check Microsoft Graph API. Which uses all the Office 365 Apps connected with API endpoints.
