I am working on a payment module for linkpoint. I had done a devel one for e_commerce and had messaged the developers for the uc one but they plan to wait and I want to proceed asap for drupalcommerce.
The issue I have is that the linkpoint api requires a phone number to be submitted as part of its billing information. I am not sure of the appropriate way to request a phone number in the billing information asked during checkout. Perhaps the addressfield project can be extended by some hook or function or it is done with some function on the commerce checkout or payment?
I did post days ago on the drupalcommerce forum asking for suggestions, but it appears posting on issues here has more activity, apologies.
