I am an experienced programmer in the process of using the FreeAgent API to interrogate outstanding invoices.
I am struggling to grasp the FreeAgent authentication required to access my live FreeAgent account.
Can someone please supply some sample code for hello world example such as count the number of overdue invoices or point myself to some online sample code. So that I can understand the steps required for authentication to my live FreeAgent accounts. The example code can be in Python, PHP or java.
Also which is the best language to access the FreeAgent API.
Thanks in advance.
