I've just purchased a CB/CBsubs licence to build an e-commerce system for a client who already has a Streamline Merchant Account and so would like a Gateway. Reading the latest forums it seems there is an API but is not yet documented (Dec 2010). The current install guide states "Subscriptions API will enable new gateways to be developed by third party developers in collaboration with CBSubs team." If we wish to build our own gateway please could you clarify how we could do this without documentation or how such collaboration would work? We would like to start asap.
Thanks in advance and apologies if I've missed something obvious.
