Order fulfillments to gift cards connection

Hi,
I have a client who would like to synchronize gift card IDs on orders to ERP once they are fulfilled in Shopify.

Is there a way to connect order line items to created/fulfilled gift cards in Shopify using the graphql API? I can’t seem to find it.

In the REST API, there is a deprecated field “receipt” on the fulfillment resource that holds an array of gift cards and a reference to the line item ID. But I see no equivalent in the graphql API.

Am I missing something, or is this not possible?

Kind regards
Frederik
