I am a noob in paypal and i have been struggling on how to use paypal api using sandbox. Then i realize maybe i can't use the API because i dont have a merchant account.
What i want to do is make my paypal unhosted buttons secure in sandbox. When using unhosted buttons in sandbox, the email of the merchant is exposed, including the price for the payment etc.. So i want to prevent that from being exposed. I can't use hosted buttons because it won't let me customize the price.
I have searched about how to make my buttons secure and then i found out about API and also paypal IPN. But i seem to get lost on the instructions. Probably because my access are limited because i dont have a real merchant account?
So is it necessary to have myself a merchant account for paypal to access the API and make my buttons secure?
