-# Use custom API
-
-If your API is not supported yet, you can write your own DNS API.
-
-Let's assume you want to name it 'myapi':
-
-1. Create a bash script named `~/.acme.sh/dns_myapi.sh`,
-2. In the script you must have a function named `dns_myapi_add()` which will be called by acme.sh to add the DNS records.
-3. Then you can use your API to issue cert like this:
-
-```
-acme.sh --issue --dns dns_myapi -d example.com -d www.example.com
-```
-
-For more details, please check our sample script: [dns_myapi.sh](https://github.com/Neilpang/acme.sh/blob/master/dnsapi/dns_myapi.sh)
