Open banking solutions in Sweden?

I'm looking at implementing an open banking alternative to my CRM allowing users to charge others without the risk of chargebacks all while providing a good UX.

From what I have heard, Sweden is rather strict when it comes to C2B settlement accounts. I have been recommended: Nordea, SaltEdge, Neonomics, applied to all of them as of yesterday.

I need a solution asap as we have gone from processing ~$100k monthly down to $10k abruptly. We have other clients on our waitlist who are willing to use the CRM once we can provide a stable solution for payments with good conversions (not Stripe), which would bring us up to around $800k monthly revenue.

TLDR: Anyone got connections in Open banking for a Swedish market? Preferred quick delivery of API key, good customer UX.

I recommend focusing on Open Banking PIS. Your best options are leading aggregators with direct connections to banks: Tink, TrueLayer, and Neonomics

These providers will give you API keys and ready-made solutions for a smooth user experience when payments are sent straight from the payer's account to your customer's account, avoiding the risk of chargebacks
