It sounds to me like your either wanting to register DNS server hostname addresses, assign a name zone entries.
Their API is too primitive to support this, not to be offending, it is still very young.
I recommend implementing your own wrapper for the site.
Some thing's to watch out for: Have an queue manager: as to only perform a single request at a time. Use a cookie jar that lasts until detected session expires and do not have it logout: this will prevent you from having to write an captcha decoder, which is fairly simple for their captcha system. Learn XPATH/DOM Queries and RegEx Have an local repo of what is in the system and what is expected in the system as to not have to query their server each time. Do not download images, unless it is an needed one for session cookies. Try to limit requests to an single IP.
Yeah thx, but the problem is, that i can´t define an ip there for the new domain. I can only register the domain. How can i make an ip entry? Is this only in the account area possible?
Your question is a little unclear, but I'll try my best.
You will need a program/script to send your requests.
You need to enter your API Key into this program/script. The API Key is available from your account area:
Where can I find my API settings?
Manage your domains with Dynadot's API! We have all the tools you need to build and use your own software and servers to search for domains, register domains, dropcatch domains, and more.
