14 Unique Use Cases of WhatsApp Business API in Fintech
Let’s get specific. Here are 14 high-impact ways fintech businesses are using WhatsApp Business API to drive engagement, boost conversions, and simplify operations.
1. Instant KYC Updates & Notifications
Keep users in the loop during the KYC process. Send status updates, document reminders, or approval messages instantly, avoiding delays and drop-offs.
Sample WhatsApp KYC Message: “✅ Great news! Your KYC has been approved. Your account is now fully activated. You can: • Start investing • Transfer funds • Apply for loans Tap to get started: [Link]”
