Hi,
I did use the Integromat and also tried with Postman - created my custom private app credentials - all with the same result - either 406 or 400 or 404 or “continue” login page.
Also, I do not know how to get parent id - for order created directly from Shopify, there is no such thing. If I try to get all transactions for order again “continue” login page result.
