alternative then to fetch Line Item data from an order with the Payments API

Webhooks and Events

We are building a payment extension for them, but we’ve hit a roadblock in regards to fetching line item data from the checkout/order that a customer is placing. For this, we were using the CHECKOUT_UPDATE/CHECKOUT_CREATE webhooks, but it seems that it’s only possible to use when requesting access to Protected Customer Data, which apparently a Payments App can’t use.

Is this correct? What is the alternative then to fetch Line Item data from an order with the Payments API, or through a Payments App?

Just to confirm - did you request this via the partner dashboard as described here: https://shopify.dev/docs/apps/launch/protected-customer-data ?
