  1. Sign up and register a
    National Australia Bank
    Gateway Portal
     sandbox account. See Sign Up for a Sandbox Account.
  2. Create a shared secret key. See Create a Shared Secret Key Pair.
  3. Construct a message using HTTP signature security. See Construct Messages Using HTTP Signature Security.
  4. Go live by signing up and registering a

Sign Up for a Sandbox Account

The first step to set up your account is to sign up for a sandbox account. From this account you can obtain your security keys and test your implementation.
To create a sandbox account, contact customer support: https://nabgateway-developer.nab.com.au/support/contact-us.html.

Construct Messages Using HTTP Signature Security

HTTP signatures use a digital signature to enable the receiver to validate the sender's authenticity and ensure that the message was not tampered with during transit. For more information about HTTP signatures, see the IETF Draft that is maintained by the IETF HTTP Working Group (https://httpwg.org).
Follow these steps to implement HTTP signatures:
  1. Create the shared secret key pair. See Create a Shared Secret Key Pair.
  2. Generate a hash of the message body. See Generate a Hash of the Message Body.
  3. Generate a signature hash. See Generate the Signature Hash.
  4. Populate the
    signature
     header field. See Update Header Fields.

Going Live

When you are ready to process payments in a live environment, you must transition your account to a live status with a valid configuration for your chosen payment processor. When live, your transaction data flows through the production
National Australia Bank
 gateway, to your processor, and on to the appropriate payment network.
To transition your account:
  1. Sign up for a merchant account.
  2. Contact Sales
     to establish a contract with
    National Australia Bank
     that enables you to process real transactions and receive support.
  3. Submit a merchant ID (MID) activation request.
It may take up to three business days to complete a MID activation request.
