Hey there, @Damidez
Bo here from Shopify Support!
I am sorry to hear this. To be honest, this is something a lot of payment gateways will be requesting of you in order to work with them. If you are serious about running your own business you would most definitely be better off obtaining the required documentation to do so. You can check out our full range of payment gateway integrations available to you here.
I'd also recommend taking a look at our Shopify webinars while you are getting started. These short tutorials take you through all the basics of creating a store such as adding products, variants, collections, theme changes and pointing a domain to your store. You should be able to sign up here if you would like. We also have a free business course with our Shopify Academy that I would really encourage you to look at if you get a chance.
All the Best,
