Class PaymentApiHooks

• TopLevel.Object
  • dw.extensions.paymentapi.PaymentApiHooks

PaymentApiHooks interface containing extension points for customizing Payment API requests for authorization, and their responses.

These hooks are executed in a transaction.

The extension points (hook names), and the functions that are called by each extension point. A function must be defined inside a JavaScript source and must be exported. The script with the exported hook function must be located inside a site cartridge. Inside the site cartridge a ‘package.json’ file with a ‘hooks’ entry must exist.

1"hooks": "./hooks.json"

The hooks entry links to a json file, relative to the ‘package.json’ file. This file lists all registered hooks inside the hooks property:

1"hooks": [
2     {"name": "dw.extensions.paymentapi.beforeAuthorization", "script": "./payment.ds"}
3     {"name": "dw.extensions.paymentapi.afterAuthorization", "script": "./payment.ds"}
4]

A hook entry has a ‘name’ and a ‘script’ property.

• The ‘name’ contains the extension point, the hook name.
• The ‘script’ contains the script relative to the hooks file, with the exported hook function.

This class does not have a constructor, so you cannot create it directly.
