How do I get all contact data?

How do I get all contact data?

I am having trouble getting contact data back from the API. I want to get all columns of data for all contacts.

The API doc says to do it like this (I used my actual token in the request):

https://crm.zoho.com/crm/private/xml/Accounts/getRecords?newFormat=1&authtoken=MYTOKEN&scope=crmapi&fromIndex=1&selectColumns=contacts(All)&toIndex=200

However all I seem to get as a result is a list of Account ID's.

I tried to specify some specific columns by altering the Querystring:

selectColumns=contacts(Name,Email)

and still just get a list of account IDs.

Can anyone tell me what I am doing wrong?

Thanks in Advance,

Gabriel
