Braintree is one of the services of the PayPal group, offering a safe and efficient API as well as a collection of libraries and tools that allow you to easily implement a secure payment model in a web or mobile application. The platform allows you to accept one-off and recurring payments with credit cards and other channels such as Apple and Google Pay. The tools and libraries ensure the highest level of security, ensuring that none of the information related to the user's cards are ever on the application server. Braintree is i.a. used by platforms such as Uber, Airbnb, Facebook or GitHub.
