Methods and systems for enhanced endpoint identity validation in electronic transactions

1. A method for merchant system identity validation, comprising:

generating, by an access management system, a primary key associated with an integrator system;

transmitting, by the access management system, the primary key to the integrator system;

generating, by the access management system, a hash value associated with a merchant system;

transmitting, by the access management system, the hash value to the merchant system;

receiving, by the access management system, an authorization request comprising a key-hash pair;

determining, by the access management system, that the key-hash pair matches a reference key-hash pair stored in a validation database;

validating, by the access management system, the key-hash pair based on determining that the key-hash pair matches the reference key-hash pair stored in the validation database; and

transmitting, by the access management system, the authorization request to an acquirer processor based on validating the key-hash pair.

2. The method of claim 1 , wherein the integrator system transmits the primary key to the merchant system.

3. The method of claim 2 , wherein the key-hash pair comprises the primary key and the hash value transmitted to the merchant system.

4. The method of claim 1 , wherein the hash value is generated in response to a request for a hash value from the merchant system.

5. The method of claim 1 , wherein the validation database comprises primary keys and hash values that are previously-generated by the access management system.

6. The method of claim 1 , wherein the primary key is unique to the integrator system and the hash value is unique to the merchant system.

7. The method of claim 1 , wherein the authorization request is received from one of:

the integrator system; and

the merchant system.

8. A system for merchant system identity validation, the system comprising:

one or more processors;

at least one data storage comprising instructions which, when executed by the one or more processors, cause the one or more processors to perform a method comprising:

generating, by an access management system, a primary key associated with an integrator system;

transmitting, by the access management system, the primary key to the integrator system;

generating, by the access management system, a hash value associated with a merchant system;

transmitting, by the access management system, the hash value to the merchant system;

receiving, by the access management system, an authorization request comprising a key-hash pair;

determining, by the access management system, that the key-hash pair matches a reference key-hash pair stored in a validation database;

validating, by the access management system, the key-hash pair based on determining that the key-hash pair matches the reference key-hash pair stored in the validation database; and

transmitting, by the access management system, the authorization request to an acquirer processor based on validating the key-hash pair.

9. The system of claim 8 , wherein the integrator system transmits the primary key to the merchant system.

10. The system of claim 9 , wherein the key-hash pair comprises the primary key and the hash value transmitted to the merchant system.

11. The system of claim 8 , wherein the hash value is generated in response to a request for a hash value from the merchant system.

12. The system of claim 8 , wherein the validation database comprises primary keys and hash values that are previously-generated by the access management system.

13. The system of claim 8 , wherein the primary key is unique to the integrator system and the hash value is unique to the merchant system.

14. A non-transitory computer readable medium for merchant system identity validation, the 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 comprising:

generating, by an access management system, a primary key associated with an integrator system;

transmitting, by the access management system, the primary key to the integrator system;

generating, by the access management system, a hash value associated with a merchant system;

transmitting, by the access management system, the hash value to the merchant system;

receiving, by the access management system, an authorization request comprising a key-hash pair;

determining, by the access management system, that the key-hash pair matches a reference key-hash pair stored in a validation database;

validating, by the access management system, the key-hash pair based on determining that the key-hash pair matches the reference key-hash pair stored in the validation database; and

transmitting, by the access management system, the authorization request to an acquirer processor based on validating the key-hash pair.

15. The non-transitory computer readable medium of claim 14 , wherein the integrator system transmits the primary key to the merchant system.

16. The non-transitory computer readable medium of claim 15 , wherein the key-hash pair comprises the primary key and the hash value transmitted to the merchant system.

17. The non-transitory computer readable medium of claim 14 , wherein the hash value is generated in response to a request for a hash value from the merchant system.

18. The non-transitory computer readable medium of claim 14 , wherein the validation database comprises primary keys and hash values that are previously-generated by the access management system.

19. The non-transitory computer readable medium of claim 14 , wherein the primary key is unique to the integrator system and the hash value is unique to the merchant system.

20. The non-transitory computer readable medium of claim 14 , wherein the authorization request is received from one of:

the integrator system; and

the merchant system.
