Asanpay is a digital payment system in Azerbaijan (part of the "Asan" ecosystem of services, similar to e-government payment gateways). A technical or security paper on this topic would focus on verifying its communication protocol (e.g., HTTPS/TLS, API request-response structure, digital signatures, and payment confirmation flows).

Asanpay, payment protocol verification, API security, TLS testing, idempotency. 1. Introduction Digital payment systems must guarantee authenticity, integrity, and non-repudiation . Asanpay, operated by the Central Bank of Azerbaijan’s partner institutions, processes thousands of daily transactions. However, protocol-level flaws—such as weak signature schemes or improper redirect validation—can lead to financial fraud. This paper aims to answer: How can one systematically verify that the Asanpay protocol behaves as specified and securely? 2. Background Asanpay typically follows a REST API pattern over HTTPS. Merchants or users initiate a payment request; Asanpay returns a transaction ID and a payment URL; after user authentication, Asanpay calls back the merchant’s webhook with a status update.

Verification of the Asanpay Protocol: A Security and Reliability Analysis Author: [Your Name] Affiliation: [Your Institution/Organization] Date: April 14, 2026 Abstract Asanpay is a widely used electronic payment gateway in Azerbaijan, facilitating secure online transactions for government and commercial services. This paper presents a methodology for verifying the Asanpay protocol —focusing on cryptographic integrity, endpoint validation, and transaction consistency. Using a black-box testing approach, we examine HTTP headers, TLS configurations, request signing mechanisms, and callback idempotency. Our findings indicate that while Asanpay implements standard security practices, certain areas (e.g., nonce reuse vulnerability and timeout handling) require further hardening.
