Can i set WHMCS to automatically activate domains at godaddy ?
I do not see godaddy at the registrars.

As far as I know you can not but I may be mistaken. If you do not see them in the registrars then I'm guessing it's a no.

GoDaddy is not a reseller service and does not have an API for WHMCS to communicate over, so no.

Godaddy does have a API Reseller for selling domain names. http://www.godaddy.com/gdshop/reseller/api.asp?ci=9058

I've seen an WHMCS add-on module for Godaddy out there.

i was thinking that there should be add-on.
godaddy is very big domain register so it will be very bad if i can`t use WHMCS for automatically order domains :(

Here's a link http://wiki.whmcs.com/Contribution:GodaddyModule

Looks like there is some effort needed to get it up and running.

Yes there is GoDaddy module for whmcs and it is very useful , because some of our clients prefer their domain names to be registered from godaddy.

I dont find there any godaddy modules for whmcs....as some of our members say "yes".....it would be appreciated

does whmcs make all the modules? or do the companys make them?

yeah but godaddy API is 249$ for one year...that is big price for that.

Just find "wilwestdomains", which is the brand of Godaddy's reseller service

correction:
it should be "wildwestdomain"
