This script demonstrates a basic COQL query setup for testing and initial response verification. Ensure your Zoho connection is properly configured and COQL is enabled in its scope.

```zoho
coqlurl = "https://www.zohoapis.com/crm/v3/coql";
queryMap = Map();
query = "select Last_Name from Contacts where Last_Name is not null"
queryMap.put("select_query", query);
response = invokeUrl [
url: coqlurl
type: POST
parameters: queryMap.toString()
connection: "zcrm"
];
info response;
```
