Hello!
Tell me how can I add “shipping lines” to an existing order?
I know that cannot change shipping lines using the Shopify API.
In the documentation, I found that it can be edited the Shopify GraphQL:
- Add new variant line items
- Add new custom line items
- Remove line items
- Alter line item quantities
Also found a similar question: LINK . This question says that shipping lines can be edited. But in the documentation I have not found how to do this.
Thanks!
