Methods and systems for enhanced endpoint identity validation in electronic transactions

A system for validation of a merchant system, the system comprising:

• one or more processors;
• and
• at least one data storage storing instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, by the merchant system, a primary key from an access management system;
• in response to receiving the primary key, transmitting, by the merchant system, a request for a hash value to the access management system;
• receiving, by the merchant system, the hash value from the access management system;
• generating, by the merchant system, a key-hash pair using the primary key and the hash value;
• and
• transmitting, by the merchant system, an authorization request to the access management system, wherein the authorization request includes transaction data and the key-hash pair, and wherein the merchant system is validated based on determining that the key-hash pair matches a reference key-hash pair stored in a validation database.

A non-transitory computer readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform a method for validation of a merchant system, the method comprising:

• receiving, by the merchant system, a primary key from an access management system;
• in response to receiving the primary key, transmitting, by the merchant system, a request for a hash value to the access management system;
• receiving, by the merchant system, the hash value from the access management system;
• generating, by the merchant system, a key-hash pair using the primary key and the hash value;
• and
• transmitting, by the merchant system, an authorization request to the access management system, wherein the authorization request includes transaction data and the key-hash pair, and wherein the merchant system is validated based on determining that the key-hash pair matches a reference key-hash pair stored in a validation database.
