Here say i want to figure out how to get the subscription plan id in the received response, then in the table i have to click payment\_link \> CheckoutOptions \> CustomField \>subscription\_plan\_id . So I have to click 4 buttons in order to search for a term…

Is there any other easy way to find it with less button clicking? or is there any schema metadata that i can refer? please let me know

I’m not sure I fully understand the question. What buttons are you referring to? Are these buttons in the Square Dashboard? 🙂

Hello,  
Yes, there are a few potential ways you can simplify finding a deeply nested field like payment\_link \> CheckoutOptions \> CustomField \> subscription\_plan\_id, depending on the tools or platform you’re working with. Here’s how you can reduce the effort:

Use JSON Viewers or Expand All Functionality (if it’s a JSON response)  
If you’re working with an API response in JSON format:def find\_key(data, target):  
if isinstance(data, dict):  
for key, value in data.items():  
if key == target:  
return value  
result = find\_key(value, target)  
if result is not None:  
return result  
elif isinstance(data, list):  
for item in data:  
result = find\_key(item, target)  
if result is not None:  
return result  
return None

result = find\_key(response\_json, ‘subscription\_plan\_id’)
