# Frameworks The Braintree iOS SDK is organized into a family of frameworks. ### Differences from Braintree-iOS 3.x * Frameworks and Carthage support * Tokenization key support * `BTAPIClient` instead of `BTClient` * `BTTokenized` instead of `BTPaymentMethod` * Refactored tests and added tests in Swift ## BraintreeCore This is the core set of models and networking needed to use Braintree in an app or extension. All other frameworks depend on this. <sub>PRIMARY CLASS:</sub> ### `BTAPIClient`: Braintree API client * Authentication with tokenization key / client token * Access configuration from gateway * Analytics * HTTP methods on Braintree API endpoints #### Other Classes * `BTAppSwitch`: Class and protocol for authentication via app switch * `BTJSON`: JSON parser ## Payment Options The Braintree iOS SDK currently supports 6 payment options. 1. `BraintreeCard`: Credit and debit card * No dependencies other than `BraintreeCore` 2. `BraintreeApplePay`: Apple Pay * Depends on `PassKit` 3. `BraintreePayPal`: PayPal * No dependencies other than `BraintreeCore` * Use `BTPaymentDriverDelegate` to receive app switch lifecycle events 4. `BraintreeVenmo`: Venmo * Depends on `BraintreeCard` 5. `Braintree3DSecure`: 3D Secure * Depends on `BraintreeCard` * Use `BTViewControllerPresentingDelegate` (required) for cases when a view controller must be presented for buyer verification ## BraintreeCard Tokenizes credit or debit cards. <sub>PRIMARY CLASS:</sub> ### `BTCardTokenizationClient`: Tokenizes credit and debit card info #### Other Classes * `BTCardTokenizationRequest`: Raw credit or debit card data provided by the customer * `BTTokenizedCard`: A tokenized card that contains a payment method nonce ## BraintreeUI A pre-built payment form and payment button. Optionally uses these payment option frameworks, if present: `BraintreeCard`, `BraintreePayPal`, `BraintreeVenmo`. ### Features * UI * Card form * Drop-in ## BraintreePayPal Accept payments with PayPal app via PayPal One Touch. ### Features * `BTPayPalDriver`: Coordinates paying with PayPal by switching to the PayPal app or the web browser * **Future payments** via `-authorizeAccount...` * `BTTokenizedPayPalAccount`: A tokenized PayPal account that contains a payment method nonce * **Single payments** via `-checkoutWithCheckoutRequest...` * `BTTokenizedPayPalCheckout`: A tokenized PayPal checkout that contains a payment method nonce * `BTPayPalCheckoutRequest`: Options for a PayPal checkout flow ## BraintreeVenmo **Depends on BraintreeCard.** Accept payments with a credit or debit card from the Venmo app via Venmo One Touch. ### Features * `BTVenmoDriver`: Coordinates switching to the Venmo app for the buyer to select a card * `BTVenmoTokenizedCard`: A tokenized card from Venmo that contains a payment method nonce ## BraintreeApplePay **Depends on `PassKit`.** Accept Apple Pay by using Braintree to process payments. ### Features * `BTApplePayTokenizationClient`: Performs tokenization of a `PKPayment` and returns a tokenized Apple Pay payment instrument * `BTTokenizedApplePayPayment`: A tokenized Apple Pay payment that contains a payment method nonce ## Braintree3DSecure **Depends on `BraintreeCard`.** Perform 3D Secure verification. ### Features * `BTThreeDSecureDriver`: Coordinates 3D Secure verification via in-app web view * `BTThreeDSecureVerification`: Card/transactions details to be verified * `BTThreeDSecureTokenizedCard`: A tokenized card that contains a payment method nonce * `liabilityShifted`: 3D Secure worked and authentication succeeded. This will also be true if the issuing bank does not support 3D Secure, but the payment method does * `liabilityShiftPossible`: The payment method was eligible for 3D Secure * These parameters pass through the client-side first and should not be trusted for your server-side risk assessment
