I need the customers CC info for use of my bot (purchasing limited fashion items online) and was wondering on the best way to do this.
This is what's generally known as a Bad Idea. You are basically saying to your customers "Hand me your credit card so that I can buy things on your behalf at some point in the future". They have no way to know you won't buy yourself nice things at their expense. You have no way to know whether the card you're using has expired, been cancelled, been reported stolen, or is even actually the customer's card and not a fraudulent one until you try to use it - at which point you could be the one on the hook for making fraudulent payments. Or you'll get angry customers because your unexpected charge put them over their credit limit, or prevented them from putting something else big on it. And so on. By using someone else's card to make purchases, even on their behalf, you're opening yourself up for a whole host of problems. That's not even touching the PCI requirements around storing credit cards, which is a whole separate can of worms.
The correct way to do something like this, if there is such a thing, is to collect the customer's payment information as "card on file" through a secure website, such as PayPal or one of their competitors. This will give you some form of identifier or token which you can use to tell PayPal to charge that card in the future. You then make purchases using your money, and then bill the customer for that amount by using that token. Or, if your bot is smart enough, you bill the customer and then make the purchase if the charge on their card goes through.
That's really the only safe way to go about this.
