Connect your service to Google Chat
Build Chat apps that bring your services and resources right into Google Chat, letting users get information and take action without leaving the conversation.
Build interactive cards that help people get work done
Cards provide a standard interface that ensures your Chat app looks good on any device. Interactive elements like buttons enable users to do their work directly from Google Chat.
Simplify complex interactions
Dialogs are windowed, card-based interfaces that Chat apps open to interact with users.
