Authentication and Authorization

Authentication and authorization are crucial concepts in information security, especially in computer systems and networks. In payment gateway services, authentication and authorization are essential processes ensuring the security and validity of financial transactions.

When you register as a merchant, Espay Payment Gateway will provide the credentials (API Key, Signature, Password, Merchant Code) required for integration in a development or production environment. These credentials verify your identity and ensure the request legitimately comes from you. Apart from checking credentials, Espay Payment Gateway will also verify your IP Address. Register your IP Address on the Espay Payment Gateway allowlist to ensure smooth communication. You can also register the Espay Payment Gateway IP Address on your whitelist.

If the authentication process is complete and the Espay Payment Gateway declares your request valid, your request will enter the authorization stage. Espay Payment Gateway will verify your transaction details, such as payment channel and transaction amount. If your transaction request is declared valid, payment will be processed.
