Understood. The Seylan payment integration code is fully written in backend/routers/payments.py. When you're ready to connect it to the live gateway, you'll need to add these four environment variables to your backend server:

• SEYLAN_HOST — the Seylan gateway base URL (e.g. https://crm.seylan.lk/ipg)
• SEYLAN_MERCHANT_ID — your merchant ID from Seylan
• SEYLAN_API_PASSWORD — your API password from Seylan
• FRONTEND_URL — your frontend URL for the redirect after payment (e.g. https://yoursite.com)

You can add them via your Render backend service's Environment settings whenever you're ready.

Now let me read the existing admin user section and the AccountRole enum and UserCreate schema:

I have everything I need. Now I'll add the POST /admin/users endpoint and a dedicated response schema. The admin create flow should:

• Accept customer, business, or admin role
• Skip rate limiting (admin is trusted)
• Auto-create a BusinessAccount when role is business
• Return the full user details without issuing a token (admin is creating on behalf of someone)

Now make sure BaseModel is imported in admin.py since AdminUserCreate uses it:

BaseModel is not yet imported in admin.py. Let me check what's at the top and add it:

One new endpoint POST /admin/users has been added to admin.py. It accepts full_name, email or phone, password, role (customer, business, or admin), and optional nic_number, is_verified, business_name, and business_address fields. When role is business or admin, a BusinessAccount is automatically created and linked to the user, matching the same pattern as the public registration flow. A welcome notification is sent to the newly created account on success.
