Form data body with an array parameter

I have created a REST API query with form data body.
Is it possible that this query has a parameter of array type (array of strings)?
So let's say that I want:
key = my_array
values = ["a", "b"]

Hi @vchris. Yes! It should be possible to use an array of string and plug it into your query. Could you share a screenshot or screen recording of what errors you're getting and how you're setting this up? This will give me a better understanding of how I can help. :slightly_smiling_face:
