"If you want to sell something on a platform it's a common to activate payment providers which you plan to use and fill in necessary credentials." - it is common for platforms to simplify the process by enabling the connection to a sellers Stripe account through entering their credentialed email address. They do not require them to enter keys. I use Stripe in multiple other businesses and all I had to do was enter my Stripe email address to connect my selling platform with Stripe. This was the initial point I was making in the thread before I went down a rabbit hole to find a possible solution. See substack as an example, not the solution but an example of simplicity. The current UNA Stripe integration is too complicated for sellers compared to other platform integrations, not just substack. Am I not seeing an alternative way to connect seller UNA account to Stripe?
