I ended up with another system, as Payfort were horribly slow to process the application. There were months of waiting with hardly any progress.
Which country are you in?
If you’re based in UAE or another ME country, then https://www.tap.company/ were very quick to respond and help with implementation. They are based in Kuwait.
If you’d like to stick with Payfort, then I would check out the API Connector plugin for Bubble. It will allow you to connect to most API’s without too much trouble.
On thing you should know is that Bubble uses a dynamic IP unless you have a dedicated server, which means that you can’t use the Telr gateway. I burned several weeks going down that road.
No idea if you were contemplating using it, but thought I should mention it.
