AWS End User Messaging Introduces Advanced OTP Tracking with Message Feedback API AWS has introduced a sophisticated method for tracking One-Time Password (OTP) delivery and usage through its End User Messaging Message Feedback API. The solution addresses key challenges in OTP verification by providing first-party data tracking that goes beyond traditional delivery receipts. The approach involves a two-phase process: first, sending an OTP with message feedback enabled, and second, updating the message status based on verification success. Organizations can now more accurately measure authentication success rates and identify verification issues across different regions and carriers.
