How can the WhatsApp for Business API be used?

With 2 billion active users, WhatsApp is, after SMS, the world’s most popular mobile messaging app. It’s popular because it’s free, you can have group chats, it’s very secure, and you can share rich media. An average user opens Whatsapp more than 20 times a day making it the perfect channel for driving better engagement with your customers.

The WhatsApp for Business API is designed for conversations between your brand and individual customers. It’s intended for customer care conversations, marketing, and what we call transactional messages – alerts, updates, notifications, reminders. Either you or the customer can start a conversation, which you can either handle with a live agent, or automate responses via a chatbot.

Chat/ Customer support

Live chat environments are great for real-time customer service interactions, but it’s not always convenient for a customer to login to an account or go to a website, where such an interaction can take place. The WhatsApp for Business API allows customers to have the same types of live interactions, with none of the live chat pre-requisites. The API can be integrated with your existing CRM for an easier, faster, and centralised communications approach for your business.

Example applications include:

  • Payment processing
  • Order queries
  • Contract/policy updates
  • FAQs

Rich notifications

An informed customer is a happy customer, and that’s where WhatsApp for Business can help. You’ll be able send media-rich notifications which grab the customer’s attention in a more effective way, using an application the average user already spends an average 195 minutes on per week (Source).

Example applications include:

  • Order confirmations
  • Delivery updates
  • Appointment reminders (with links to re-scheduling tools)
  • Event invitations
  • Payment reminders
  • Service interruptions (E.g. utilities)

Making sure that your message has arrived, and more importantly been read, is often critical to any project. The delivery and read notifications within WhatsApp make it easy for senders to be reassured that their message has been engaged with.

Example applications include:

  • Travel updates with links to rescheduling tools
  • Facility closures (E.g. schools, and healthcare facilities)
  • IT outage alerts
  • Security breaches
  • Account updates (E.g. banking, council-tax statements)

The rich content delivered via WhatsApp engages your customers, encouraging them to act immediately through promotional messages delivered directly to their fingertips.

Example applications include:

  • Flash sales
  • New product launches
  • Upsells (upsell marketing following an initial sale)
  • Digital coupon delivery
  • Drive to website
