A suite of tools for integrating Braintree in the browser.
This is the repo to submit issues if you have any problems or questions about a Braintree JavaScript integration.
For a ready-made payment UI, see Braintree Web Drop-in .
npm install braintree-web
bower install braintree-web
For more thorough documentation, visit the JavaScript client SDK docs .
If you are upgrading from version 2.x, take a look at our migration guide .

To be eligible for the easiest level of PCI compliance (SAQ A), payment fields cannot be hosted on your checkout page. For an alternative to the following, use Hosted Fields.
braintree . client . create ( {
authorization : CLIENT_AUTHORIZATION
} , function ( err , client ) {
client . request ( {
endpoint : ' payment_methods/credit_cards ' ,
method : ' post ' ,
data : {
creditCard : {
number : ' 4111111111111111 ' ,
expirationDate : ' 10/20 ' ,
cvv : ' 123 ' ,
billingAddress : {
postalCode : ' 12345 '
}
}
}
} , function ( err , response ) {
} ) ;
} ) ;
For more examples, see the reference .
All the asynchronous methods will return a Promise if no callback is provided.
var submitBtn = document . getElementById ( ' my-submit ' ) ;
var yourStylesConfig = { } ;
var yourFieldsConfig = { } ;
braintree . client . create ( { authorization : CLIENT_AUTHORIZATION } ) . then ( function ( client ) {
return braintree . hostedFields . create ( {
client : client ,
styles : yourStylesConfig ,
fields : yourFieldsConfig
} ) ;
} ) . then ( function ( hostedFields ) {
submitBtn . addEventListener ( ' click ' , function ( event ) {
event . preventDefault ( ) ;
submitBtn . setAttribute ( ' disabled ' , ' disabled ' ) ;
hostedFields . tokenize ( ) . then ( function ( payload ) {
} ) . catch ( function ( err ) {
submitBtn . removeAttribute ( ' disabled ' ) ;
console . error ( err ) ;
} ) ;
} ) ;
} ) ;
