Hello Team,
I am trying to add a new attribute to be indexed by searchanise from magento 2 app through this request
https://www.searchanise.com/api/items/update/json
{

 "private_key": "<private-key>",

 "data": {

  "schema": {

   "ar_available": {

    "name": "Is Available In AR",

    "title": "Is Available In AR",

    "type": "int",

    "facet": {

     "type": "select"

    }

   }

  }

 }

}

but i get "invalid private key" response

I did not notice any private key during purchasing searchanise from magento marketplace and installing it except my account private key which i provided in the request above but invain

Could you please tell me where can i find the private key needed ?

Thanks in advance.
