Develop Google Chat apps
Use the Google Chat API to 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. Help users complete multi-step processes with sequential dialogs.
Promote productive collaboration
With link previews, whenever users share links in Google Chat spaces, your app can attach cards with helpful information that let people take action right from Google Chat.
