There are two forms of authentication available:
  • HTTP Signature is a hash-based method which uses a shared secret key.  
    • A shared secret key is a Base64-encoded transaction key string.
    • You authenticate to the API using this key, which is unique to your account.
    • Visa Acceptance uses it to connect your website or API integration to the Visa Acceptance Payment Gateway for transaction processing.
    • It is different from your login credentials for the Visa Acceptance Portal
  • JSON Web Token (JWT). This requires signing a P12 Certificate 
    • A certificate is one way to authenticate to APIs.
    • The certificate contains public and private keys unique to your account.
    • Visa Acceptance generates the public key.
    • You generate the private key from a Java Network Launch Protocol (JNLP) file provided by Visa Acceptance.
    • Note: Certificate authentication uses a PKCS12 key file with the .p12 extension to digitally sign your API request message before transmitting it to Visa Acceptance

If you do not have a Visa Acceptance Portal account, sign up.

Use your Visa Acceptance Portal account to create a P12 Certificate for JSON Web Token Authentication.
