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.

 "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:

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

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.
