# How do I connect Ozone Express for shipments and COD?

Install Ozone Express from Apps, then enter your API Key and Key ID to connect the courier for automatic order sync and real-time tracking.

## Steps

1. Go to **Apps > Ozone Express**.
2. Click **Connect Account**.
3. Enter your **API Key** (at least 10 characters) and your numeric **Key ID**, both from your OzoneExpress dashboard settings.
4. Submit. A "Connected" badge appears once the credentials are saved.
5. No OzoneExpress account yet? Use **Create New Account** to register on OzoneExpress's site first.

## Common problems

- "Invalid credentials" on connect → the API Key must be at least 10 characters and the Key ID must be numeric; re-check both against your OzoneExpress dashboard.
- Order rejected with "city... not recognized by OzonExpress" → the order's city doesn't match one in OzoneExpress's coverage list; correct the customer's city and resend.
- Order rejected for phone, address, or COD amount → OzoneExpress validates recipient phone format, a complete address, and a valid cash-on-delivery amount before accepting the order.
- "This order has already been submitted to OzonExpress" → a duplicate send; check the order's existing tracking number instead of resending.
- Disconnecting → stops OzoneExpress from receiving any further orders from the store.
- Country coverage → OzoneExpress operates in Morocco; Dropify sends every order to OzoneExpress's Moroccan API.
