tough nugget. Revolut has basically 2 options (+ 1 for your business so not a plugin pathway, which needs to support multiple businesses). And out of those 2 options, Merchant API is in closed beta, and has been for quite a while. The only option that remains is for a developer to register legally as a payment service provider and enroll in Open Banking Directory to use the Open Banking API. And this is unlikely due to two reasons: 1. lots of red tape to get approved as a psp and 2. liability concerns on defaulted payments.
That's why there's no payment processing with Revolut yet. Best wait for the Merchant API to come out of beta.
