Method Not Found

Frappe Framework App Development
1

I’m trying to check if an Item exists via an HTTP GET to a frappe method. I am getting “Method Not Found”. I’m testing in Postman. /api/resource GETs are working fine.
I really need to use the frappe.db.exists() method to confirm if an Item Name (or Item Code) already exists.
I’ve tried a number of variations of the following:

GET https://erp.mysite.com/api/method/frappe.db.exists( ‘Item’, ‘AAAAA’) where ‘AAAAA’ is the item name to check
GET https://erp.mysite.com/api/method/frappe.db.exists?doctype=Item&name=AAAAA
etc.
I appreciate any guidance

Thanks!
Mike

@Mike_Z ,
To be able to access a method via REST API, it must be whitelisted, but frappe.db.exists is not.
You can achieve this by creating whitelisted method and accessing it in REST API.

Similar to this.

@frappe.whitelist()
def check_if_exists(doctype, docname):
   return frappe.db.exists(doctype, docname)
