Redirect the Merchant

Your application must redirect the merchant to National Australia Bank so that the merchant can log in with their National Australia Bank credentials and provide permissions for your application.

IMPORTANT

A merchant giving permissions to your application must log in as an Account Owner or Account Administrator.

After the merchant provides or denies permissions for your application, National Australia Bank redirects the merchant to the redirect URL that you provided when you registered. If the merchant attempted to grant permissions using an account with insufficient privileges, the redirect response is the same as when a merchant denies permission.

When you redirect the merchant to National Australia Bank, encode the URL with the following parameters as a query string:

URL-Encoded Query Parameters in Your Redirect
Parameter Name	Required	Notes
sub	Yes	Must be set to oauth .
client_id	Yes	The client ID that you received when you registered your application in the `Gateway Portal`.
redirect_url	Yes	The page to which `National Australia Bank` redirects the merchant after the merchant grants your application permissions. The value of the redirect_url parameter must exactly match the redirect URL that you supplied during registration.
state	No	Value that is sent in the response to prevent malicious interception, such as a CSRF attack.
