Custom Payment Provider - Retaining Additional Payment Data for Refund Processing from getWebhookActionAndData

[ccwei]

Hi all,

I'm building a customized payment provider with the latest release v2.5.0. In my implementation, I'm receiving the payment processing result via a webhook call from a 3rd party payment provider, so I implemented the getWebhookActionAndData method to handle it.

The issue I'm facing is that during the webhook call, the payment provider sends additional payment processing data that I would like to retain for later use during the refund process (in refundPayment). However, it doesn't seem like the current design allows storing extra payment data that can be accessed later when processing a refund.

Is there a recommended approach or best practice for retaining additional payment data in the Medusa payment provider flow so it can be retrieved during refundPayment?

Thanks in advance for the help!

for now, im manually using the payment module service and store the data in payment session data so i could retrieve it later for refund if needed.

It's a Taiwan payment provider called ECpay(https://www.ecpay.com.tw/) since I'm implementing the site for TW audience. It's one of the largest payment provider in Taiwan.
