Are there any stored procedure to create/update customer and customer contact?

SOLVED

I recently started working with sage 500 api which is really a set of stored procedures. At this stage, I want to create/update a customer as well as the corresponding contact. Does anyone have any idea of what stored procedures to use for this purpose or please point me in a good direction to kick-start this process? 

Will appreciate any kind of help because I can't find any documentation or useful stored procedures yet!
