I wanted to retrieve all the account by using the following URL:

https://crm.zoho.com/crm/private/xml/Accounts/getRecords?authtoken=XXXXXX&scope=crmapi&selectColumns=Accounts(ACCOUNTID,Account Name,Groupe)"

However, it seems to retrieve only 20 accounts with all the values and not only the accountid, name and groupe. 

Can you please explain why?

Thanks,

Stanislas
