I'm trying to run a custom function in Zoho Flow that looks up a Client Company using the Client Name. I want it to return only the matching record or an error; at the moment it's defaulting to the first reponse (I think)

Can someone help tweak this function as I feel I'm very close :

1. string ZP_getClientID(string varClientName)
   
2. {
   
3. payload = Map();
   
4. payload.put("name",varClientName);
   
5. response = invokeurl
   
6. [
   
7.     url :"https://projectsapi.zoho.eu/restapi/portal/XXXXXXXXX/clients/"
   
8.     type :GET
   
9.     parameters:payload
   
10.     connection:"devteam_zoho_projects"
    
11. ];
    
12. //Change the response to a map to extract specific information
    
13. responseMap = response.toMap();
    
14. for each  varRecord in responseMap
    
15. {
    
16.     //Something here    
    
17. }
    
18. varFoundID = responseMap.get("clients").getJSON("id");
    
19. return varRecord;
    
20. }
