Overview

Why FinTech apps use the WhatsApp API

FinTech apps depend on trust and speed: users want to know instantly that a payment went through or that a document is needed. Messages from an official business number are familiar and easy to act on.

WATick supports Utility and Authentication templates for alerts and OTPs, lets users reply with documents, and connects to your app through the API and webhooks. Follow the compliance rules that apply to your business.
