How to handle/parse incoming POST requets

ERPNext

Hi,

Have a React site sending POST data to a whitelisted method on my custom app, I then need to parse this information to send to various databases including Frappes.

How does Frappe deal with incoming API requests if they are not made to the default Frappe endpoints such as http://xxx.xxx.xxx/api/resource/Customer

Thanks.
Kind regards,

@frappe.whitelist()
def get_due_date(posting_date, party_type, party, company=None, bill_date=None):
	"""Get due date from `Payment Terms Template`"""
	due_date = None
	if (bill_date or posting_date) and party:
		due_date = bill_date or posting_date
		template_name = get_payment_terms_template(party, party_type, company)

		if template_name:
			due_date = get_due_date_from_template(template_name, posting_date, bill_date).strftime("%Y-%m-%d")
		else:
			if party_type == "Supplier":
				supplier_group = frappe.get_cached_value(party_type, party, "supplier_group")
				template_name = frappe.get_cached_value("Supplier Group", supplier_group, "payment_terms")
				if template_name:
					due_date = get_due_date_from_template(template_name, posting_date, bill_date).strftime("%Y-%m-%d")
	# If due date is calculated from bill_date, check this condition
	if getdate(due_date) < getdate(posting_date):
		due_date = posting_date
	return due_date

So this is simple RPC method where paramns are sent and accessed by name it self
