Creating an Addon for specific client and product.

[Yahav]

I'm currently developing an addon module in which i'll need to programmatically add to a specific product/service the client has an addon product.

However i was not able to find any documentation on how this can be achived, the API doesn't have any method that will allow such task.

Any ideas how would i go about doing that?

EDIT:

Ok, i've figured out that i can use the AddOrder API method to add an addon to a specific service id (https://developers.whmcs.com/api-reference/addorder/)

Now i'm struggling with getting that addon domain field to be set. the addon i'm trying to assign is a cpanel/hosting package, it has a Domain custom field and so i tried using the customfields parameter with the api call, however this doesn't seem to work.
