Help with InvokeURL request

I have this command in bash that works fine-

curl -X PUT https://company.monitoringclient.com/v2.5/plugin_results/dr_71d075452e?api_key=<My_API> -d plugin_result[mute_type]="timed" -d plugin_result[mute_until]=1629928496

(I've obfuscated some variables)

I need to get this request into an invokeURL request. The issue is that I'm trying to submit 2 variables and the examples only have 1.

Also the server we submit to requires the info in either url-form-encoded or json format.

I can't get the invokeURL to submit either method without appending extra characters.

Here's what we want in form format-

Request Body

plugin_result[mute_type] : ""timed""
plugin_result[mute_until]: "1629928496"
