Azure data Factory - passing in Json array/Object into web connector

Hello,

I'm currently building a pipeline where I am calling a REST API using the web connector and then using the Copy Activity to save the data to a SQL DB. The API URL I want to use has the following structure:

https://api-url.api.com/param?start=0&limit=10&sort=[{"param1": "subparam1", "param2": "subparam2"}]

I can ping this endpoint fine in Python although having trouble building this in the Add Dynamic content section. I am currently trying:

@{concat(
'https://api-url.api.com/param?start',
variable1,
'&limit=',
variable2,
'&sort=[{"param1": "subparam1", "param2": "subparam2"}]'})

although this keeps erroring out. I've tried passing in the last part as follows:

@json (string(&sort=[{"param1": "subparam1", "param2": "subparam2"}])
string(&sort=[{"param1": "subparam1", "param2": "subparam2"}])
&sort=[[{<!-- -->{"param1": "subparam1", "param2": "subparam2"}}]]
&sort=[{""param1"": ""subparam1"", ""param2"": ""subparam2""}]
&sort=[{<!-- -->{"param1": "subparam1", "param2": "subparam2"}}]
&sort=[[{"param1": "subparam1", "param2": "subparam2"}]

However, I keep getting an error. I presume it's because of the way Data Factory is parsing this as a string.

Any explanation or help would be great.
