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) {
// Send response.creditCards[0].nonce to your server
}
);
}
);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 = {
/* your Hosted Fields `styles` config */
};
var yourFieldsConfig = {
/* your Hosted Hields `fields` config */
};
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) {
// send payload.nonce to your server
})
.catch(function (err) {
submitBtn.removeAttribute("disabled");
console.error(err);
});
});
