The WhatsApp Business Platform gives medium to large businesses the ability to connect with customers at scale. You can start conversations with customers in minutes, send customer care notifications or purchase updates, offer your customers a level of personalized service and provide support in the channel that your customers prefer to be reached on.

Cloud Firestore is a flexible, scalable database for mobile, web, and server development from Firebase and Google Cloud. Like Firebase Realtime Database, it keeps your data in sync across client apps through realtime listeners and offers offline support for mobile and web so you can build responsive apps that work regardless of network latency or Internet connectivity. Cloud Firestore also offers seamless integration with other Firebase and Google Cloud products, including Cloud Functions.
