Documentation

Detailed documentation of ODT API authentication mechanisms and all API calls is available in PDF: ODT API Specification

Code Samples

In order to make it easier for you to start with ODT API, we have created following examples in C# and PHP. In ODT API, clients use signed HTTPS POST requests to invoke API calls, server replies with JSON responses.

C# Code Sample

This sample shows how to send an authenticated API request and how to use this mechanism to call Whois Online API using synchronous and polling modes. Please read the ODT API Specification (download above) for more information about the API calling modes. Should you need any help with our API, feel free to contact our support.
