Hi Friends,

Can we make categories, or can pass a key to contact, to find that contact  
is supplier / customer.  
Because there are filters shown in document related to Contacts at free  
Agent

[https://dev.freeagent.com/docs/contacts](https://dev.freeagent.com/docs/contacts)

- clients: Show all clients.
- suppliers: Show only active suppliers.

now, I need that concept,

And I also want to know the ( Hash ) criteria for sending data (encoding /  
hashing algo ).

Hi Vipul,

The “contact category” you see there is derived from other data in the  
system: it’s not something that is specified by input. A “supplier” is  
simply a contact with bills, where a “client” is a contact with invoices or  
estimates. It’s entirely possible, therefore, for a contact to be _both_ a  
supplier and a contact.

Hope this helps,
