Client-Side Implementation
Important
The SSL certificates for Braintree Mobile (iOS and Android) SDKs are set to expire on March 30, 2026. This will impact existing versions of the SDK in published versions of your app. To reduce the impact, upgrade the iOS SDK to version 7.0.0+ for the new SSL certifications.
If you do not decommission your app versions that include the older SDK versions or force upgrade your app with the updated certificates by the expiration date, 100% of your customer traffic will fail.Get the SDK

Initialization
To use our card payment processing with your own UI, instantiate a BTCardClient and tokenize the card details.
- Swift
// For client authorization,
// get your tokenization key from the Control Panel
// or fetch a client token
let cardClient = BTCardClient(authorization: "<#CLIENT_AUTHORIZATION#>")
let card = BTCard(
number: "4111111111111111",
expirationMonth: "12",
expirationYear: "2025"
)
cardClient.tokenize(card) { tokenizedCard, error in
// Communicate the tokenizedCard.nonce to your server, or handle error
}In the completion block, send the resulting nonce to your server for use.
