Thank you very much sem for this reply, I’ve been trying to solve this problem for several weeks now, and it’s very difficult for me, even though I know it’s not complicated at all, but I’m not comfortable with APIs. I can’t match the user’s unique id on Bubble with the RC id because after payment I receive the user’s RC id on my workflow backend (webhook) and at that point there’s no proof that it belongs to the user who paid. Basically, if everything happened on the workflow and not on the workflow backend, I’d be able to do everything without any problem, but I can’t get the payment data from my workflow. I’m exhausted, I assure you. A little help to solve this problem would do me a world of good.
