Hello! I wanted to share my work which spent some time and patience.
I tried a lot of format that returns multiple errors. I also got an idea from someone here in the community but I forgot the name. Well, thanks to you.
Hope this helps! Happy coding!
This results to:
{“query” : “mutation { create_item (board_id: 3063556967, item_name: "Daily xxx" , column_values: "{\"date\" : {\"date\" : \"2022-08-15\"}}"){ id} }”}
Remember the escaping.
