Unable to Create Zoho Booking via the Booking API

Unable to Create Zoho Booking via the Booking API

I'm adding the below data to post the appointment. {"ticket_number":"1139","service_id":"4158687000000807146","workspace_id":"4158687000000468026","staff_id":"4158687000000816006","customer_details":{"name":"janak new","email":"janaktest@malinator.com","phone_number":"+919876549876"}} But it is returning the below error. {"response":{"errormessage":"EXECUTION ERROR :: Error setting value for the variable:'customer_details'\n null","status":"failure"}}

Can you please guide me on this?

I have also tried to fetch the appointment which is created by ZOHO itself without API. But it is also returning the error.
{"response":{"returnvalue":{"message":"Invalid booking_id","status":"failure"},"status":"success"}}
