I am desperat to migrate away from WHMCS to Blesta. One of the domain registrar modules that I currently use at WHMCS and wich I need, is Realtime Register. Here is their site: https://www.realtimeregister.com
Would it be possible in the near future for you to develop a Realtime Register domain registrar module? For me it is not important to be able to register and transfer domains from within Blesta, I currently only do that directly in control panel to Realtime Register. However what I need is to be able to renew the domains from within Blesta, see the expiry date, and let clients change name servers, get epp transfer codes, and change whois contact information.
If it helps, Realtime Register already has deveoped a open source WHMCS registrar module, maybe it can help looking at the source code for that module. Please note that the WHMCS module at their site is outdated and a very old version (I hope they will update it soon), but they have sent me the newest version on email. I will attach the newest version as a zip file to this forum post, so you can look at it if it helps developing a Blesta module for Realtime Register.
Thanks. whmcs_realtimeregister_v49.zip
