On our website we currently take payments for downloads, we have a cost of sale associated to this, the royalty which goes to an artist. We know how to take payments via BarclayCard however I was wondering if anyone knew how to automate a process to transfer the money to an artist. Would this need to be done on our end or would they request it?
You would generally take a single payment from your customer, and that would deposit into your merchant account.
If you want to then split that value between cost / royalties, that would need to be done at a later point. It's not something the payment gateway would get involved with.
