Integrating Microsoft Teams into a ReactTS and Next.JS application: Seeking advice and best practice

Hello,

I would like to know how to integrate Microsoft Teams into my website developed in ReactTS and Next.JS.

My goal is to enable my users (who already have a Microsoft 365 account with all the necessary paid subscriptions for using Teams) to log in directly to my Teams integration to make video calls to other Teams users. I do not want to substitute for Microsoft in managing subscriptions.

Can I use the microsoft/teams-js SDK, or another solution developed by Microsoft?

Must I necessarily use the Graph API?

Here is the list of features I want to integrate:

• create a meeting
• invite to a meeting
• make the call directly from my website
• subsequently, I would like to integrate Microsoft Teams chat

Additionally, I would like to know if this incurs costs either for me or for my users.

Thank you for your responses, and I remain at your disposal for any further details.

Sincerely,

Thibault
