Channels in one API
Challenge
A European financial services provider needed a PSD2-compliant solution for OTP messages and transaction notifications. The previous system had separate integrations for SMS and email — without WhatsApp support.
Solution
The AnyMessage Gateway (AMG) unified SMS, WhatsApp and email in a single API. OTPs are preferably delivered via WhatsApp (higher open rate), with automatic SMS fallback on failure.
„The AMG fundamentally simplified our communication infrastructure. One API for all channels — that was exactly what we were looking for."
