Renars here from Excelify.
Amazing to see you here as well as thank you for reaching out to us directly.
Just to double-confirm, was just digging through the Shopify API documentation, and indeed still currently there is no API Call that apps could make to get or create Inventory Transfer data.
But we do know that Shopify is active in the community here, and hopefully, as more people need it, it will get developed.
Thanks @Renars ... It occurred to me (afterwards, of course) that I should perhaps have asked your permission before quoting you here. oops. Happy you don't sound disturbed ... and thanks for the inputs. I did some multiple posting of your info, as there were several threads involving transfer API. Cheers jb
