Tip
Please familiarise yourself with order statuses and their lifecycle.
# The Certificate
An order's certificate looks like the following. Please note names are fictitious.

# Download the certificate
First, identify the id
of the completed order for which you would like to download the certificate.
If you don't have your order id, either find the order in the dashboard's orders page (opens new window) or you can iterate through your all orders.
Then, get your API Key (opens new window).
Now, download the certificate:
curl -X GET \
-H "Authorization: Bearer <API_KEY>" \
"https://api.lune.co/v1/orders/Vxg3b7MoBkrNQA329N0pnvmw1J8a6Lqj/certificate"
The response consists of the order's certificate pdf.
