If anybody is having similar issue, this was my workaround:
-
split items from array (from what I undertand it’s parsed as a string) using Replace to change separators from
,to",".
-
Next I added that result between
[" "]inside “fields” and my Multi-reference field (pints):
Don’t forget to add content-Type: application/json to the Headers, took me hours to figure that part off.
That was a tough battle but thanks to Mackenzie Child I got it to work!
