Campaign API requests

Campaign API requests

Hello,

I am now investigating API functionality and I can not receive leads by campaign/receive campaigns.

i want to use API on www.jettmesaj.com

When calling https://crm.zoho.com/crm/private/xml/Leads/getRecords?authtoken=token&scope=crmapi%20&select&fromIndex=10000&toIndex=10200 I am receiving all leads but there is no such field 'campaign id' or 'campaign name'.

How API calls should look like to receive campaigns list / receive leads by campaign?

Thanks
