User Profile Integration by several extension

Hello,
i'm using jomsocial, seblod, hikashop... now all three of them have their own user profile.. i setup age verification in seblod but in hikashop's registration those are not exist (of course since both are different system)

1. What the best practice for it ?
2. do you have api to integrate custom fields ?

Thanks

Hi,

I think that the best practice is to use the seblod registration, and then go to the HikaShop checkout.
In the HikaShop checkout the customer will be asked to enter his address, if it's already registered in seblod, a new plugin will be required.

In Hikashop, there's missing username field in registration form is it possible to add one and integrate with core joomla (#__user)

You can create a custom field for the username in Hikashop (Display>Custom field of type user) but it won't be added in the joomla's core.
However I guess that thanks to Seblod this field should appears, it depend of what you want to do with it.

can we use seblod article instead hikashop product in september 2013 ?
