The API can be setup for your company using "organizations", and you can attach "organizations" lower in the hierarchy that can function as subsidiaries - such as having a European HQ, with sub-organizations representing operations in France, the UK and Belgium. The API allows for an unlimited hierarchy, starting at the headquarters level and going down as far as a single department of a sub-organization, or even further, depending on the level of distinction you’re aiming for for processing online transactions.
A payment profile is a way of accounting for different incoming payment flows.
You can set payment profiles depending on region, or the type of payments you want to receive
(direct or subscription billing).
A single organization can use multiple payment profiles to distinguish incoming payments. A single payment profile is limited to a currency, and to a collection of processors. In practice, this means a single payment profile can process one currency and process using multiple processors as long as those are unique.
