## 20. Use DigitalOcean API (native)
You need to obtain a read and write capable API key from your DigitalOcean account. See: https://www.digitalocean.com/help/api/
```
export DO_API_KEY="75310dc4ca779ac39a19f6355db573b49ce92ae126553ebd61ac3a3ae34834cc"
```
Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_dgon -d example.com -d www.example.com
```
# Use custom API # Use custom API
If your API is not supported yet, you can write your own DNS API. If your API is not supported yet, you can write your own DNS API.
