How to use the HTTP API
Simple DNS Plus includes a HTTP API through which you can perform most of the operations that are available through the GUI.
The HTTP API is REST based and data is generally exchanged in JSON format.
By default, Simple DNS Plus listens for HTTP requests on IP address 127.0.0.1 port 8053.
With this default configuration, you can open the HTTP API "home page" in your browser using http://127.0.0.1:8053.
There you will find a link to the HTTP API specification file (Swagger / OpenAPI format) that you can use to explore and test the HTTP API.
You can change these setting in the Options dialog / HTTP API section.
The HTTP API can be served securely via SSL (https://...).
The easiest way to setup an SSL certificate for this, is if you are also running an SSL based web-site on IIS on the same computer as Simple DNS Plus, and you configure the HTTP API to be served under the same host name as that site (but under a sub-path). This way you can just manage the SSL certificate in IIS.
If you are not doing this or if you want to use a different SSL/TLS certificate for the HTTP API, you will need to "bind" an SSL/TLS certificate to the host name (and port) used. There is a "Bind SSL certificate" button in the Options dialog / HTTP API section to do this.
Debugging log files
To see the exact details of HTTP API client requests, you can enable this in
the Options dialog / Logging / Log files section / "Write HTTP API debugging log files (one file per HTTP request)".
WARNING: This can quickly add up to a lot of log files and data. Make sure to only enable this when needed.
