Akahu's one-off payment service uses official open banking connections to initiate payments directly from your users' New Zealand bank accounts.
Create a payment by specifying the amount, payee account details, and optional statement reference fields.
All payments require a redirect_uri. This is where the user will be returned upon completing authorisation.
Once the payment is created, send your user to the authorisation_url to complete payment authorisation.
