API Connector + Multi-select Dropdown

Does anyone know how I can map a multi-select input (a,b,c) to an API parameter as a simple array ([“a”, ”b”, ”c”])?

For example, I have a multi-select input with tags. The user can select multiple tags. I then want to make an API call like

“tags”: [

Currently, when I map the value of the select input to the “tags” parameter, it outputs a comma seperate list so I end up with a call like this:

“Tags”: “a,b,c”

Any help would be much appreciated.

Can you share what you have actually?
You will probably need to use formated as text or join with
