I want to implement domain search facility in my website. As I searched and learn I need to implement Domain search and registration API. As I never did this before and not found much knowledge base documentation on this at beginner level.
Which API I should use SOAP or REST ?
Where do I get API Key for development purpose or Do I need to purchase this?
Please let me know how can I implement or from where should I start at least.
Any help would be appreciated.
