Confirm plan_code property is included in the response for the get list subscriptions API

Confirm plan_code property is included in the response for the get list subscriptions API

We are using the Zoho Subscription API to get a list of subscriptions filtered by customer_id.
However, when I read the example response in the documentation (https://www.zoho.com/subscriptions/api/v1/subscription/#list-all-subscriptions),
I don't see the plan_code property in the response.

When I test the API in my computer, the response does have the plan_code property.

Can you help me confirm when the plan_code property is included in the response for the get list subscriptions API call?
