Customization

After a request for a particular service is built, there is a check for any code registering to the hook

app.payment.modifyrequest

. If present, the hook is called for that specific request and the request object is passed into the hook. The return value of the hook is sent to

Visa Acceptance for SMB

as the final request object. Through this process, you can inject your own data into the request object from the custom code you write in a separate cartridge.

To customize request objects, register the hook

app.payment.modifyrequest

in your cartridge's

hooks.json

file. An example would look like this, replacing the script path with your own script:

You can copy the

scripts/hooks/modifyRequestExample

script from this cartridge into your own to use as a template for extending and modifying service request objects. Note that every hook must return a valid request object for the given service. Refer to the
