Hey Richard!
The type of cursor key that Shopify send back is in the header, which Parabola can’t handle yet!
But the API that uses page based pagination, which was scheduled for deprecation this month, is still active until July 1, 2020 according to this pageL https://shopify.dev/concepts/about-apis/versioning
So you should be fine using the 2020-04 version and using page numbers!
We are planning on getting a native Shopify integration out very soon too, so keep an eye out for that!
And certainly let me know if you feel that the page based pagination is not working for you.
