WHY BUILD CUSTOM TEAMS APPS

Bring Enterprise Workflows Directly Where Your Team Works

Eliminate context switching. Instead of asking employees to open 10 different web applications, embed approvals, dashboards, ticket resolution, and conversational AI directly inside Microsoft Teams channels and chats.

Single Sign-On (SSO) with Entra ID: Instant, smooth authentication using current Microsoft 365 login credentials without extra passwords.

Interactive Adaptive Cards: Send rich interactive cards to Teams channels where users can approve requests, enter notes, and submit forms without leaving chat.

Microsoft Graph API Integration: Read and write emails, calendar events, SharePoint files, and user presence dynamically.

Cross-Device Responsive Experience: Apps function smoothly across Teams desktop, iOS, Android, and web browser clients.
