WebHare PSP Base

Base package for WebHare PSP integrations

Building a new PSP

Setup a TS (or JS) file and export a driver class implementing the PSPDriver interface from @webhare/psp-base.

We recommend using doc/dummy-driver.ts as the basis for your new payment driver, replacing Dummy with the name
of your driver.

Implement connect() first. Connect should validate the configuration and return the method(s) supported by the PSP.
Once connect() works you should be able to configure the PSP in WebHare and it should be able to show up in payment
screens

Implement startPayment to handle actual payment attempts. Inform the PSP about the returnUrl and pushUrl.

Implement processPush to receive notifications sent to the pushUrl. This function should return a status update
AND the response to provide to the notification invoker. eg:

``typescript
return {
setStatus: "approved"
response: new Response("It is done", { headers: { "content-type": "text/plain" } })
};
`

The Response` object here is part of the Fetch API - you normally shouldn't be importing this from anywhere.

Note that it's very common for processPush, processReturn and checkStatus to be nearly identical in implementation. Some providers may allow
or even require you to do a status check in your processPush or processReturn paths.
