Microsoft Teams offers a wide range of features, including text-based chat, video calling, audio conferencing, file sharing, screen sharing, online meetings, and integration with Office 365 tools. To extend these features, Microsoft provides SDKs in multiple languages, allowing users to develop their own extensions and integrations. Integrating Microsoft Teams with AWS Lambda can offer benefits, but it also comes with challenges such as CORS issues, needing a REST API endpoint for integrations, complex debugging experience, and structure of request-response object that may not be present in AWS Lambda functions. To simplify the process, using a service like Symbl.ai can provide straightforward APIs and SDKs to integrate with Microsoft Teams and access advanced AI functionalities without requiring advanced coding skills. Integrating Microsoft Teams with AWS Lambda requires setting up an AWS Lambda function, Amazon API Gateway, and configuring the app or service with Microsoft Teams for bots and webhooks.
