An example Braintree integration for Ruby on Rails

Braintree Rails Example test

An example Braintree integration for Ruby on Rails.

Setup Instructions

1. Install bundler:

   gem install bundler

2. You may need to install postgresql (a production dependency) and mimemagic. On a mac using Homebrew, run these commands:

brew install shared-mime-info
brew install postgresql

1. Bundle:

   bundle

2. Copy the contents of example.env into a new file named .env and fill in your Braintree API credentials. Credentials can be found by navigating to Account > My User > View Authorizations in the Braintree Control Panel. Full instructions can be found on our support site.

3. Start rails:

   rails server

Running Tests

Running Unit Tests

Unit tests do not make API calls to Braintree and do not require Braintree credentials. You can run this project's unit tests by calling rake (or rails -R spec) on the command line.

Running Integration Tests

Integration tests make API calls to Braintree and require that you set up your Braintree credentials. You can run this project's integration tests by adding your sandbox API credentials to .env and calling rake spec:integration (or rails spec:integration) on the command line.

Running All Tests

You can run both unit and integrations tests by calling rake spec (or rails spec) on the command line.

Testing Transactions

Sandbox transactions must be made with sample credit card numbers, and the response of a Braintree::Transaction.sale() call is dependent on the amount of the transaction.

Pro Tips

• Run rails s -b 0.0.0.0 when launching Rails server to listen on all interfaces.

Issue description

I set up your braintree example in rails 5.1.4 with ruby 2.4.2
The credit card payment word fine but the paypal checkout is stating something went wrong on our end.

I included the paypal sandbox credentials in my braintree Settings > Processing > Payment Methods > PayPal and linked the PayPal Sandbox

but it is not working.

What else can I do to test the paypal checkout?

Scrolling on iOS is sticky

When testing Node JS braintree example on iOS, Safari and Chrome, scrolling vertically is sticky (e.g. I swipe up and the page freezes, I can't scroll all the way to the bottom). When testing on Android or desktop browsers, the scrolling works fine. https://coder-kids.herokuapp.com/checkouts/new

404 error not found when creating transaction

I deployed this to heroku and I am working with the demo project in the braintree-android repo. I can get the client_token fine so I know the base URL I'm using is correct but when I get the nonce through the pop-up and try to make a transaction I get a 404 not found error. Any help is greatly appreciated

The unsuccessful credit card numbers all result in "Sweet Success!"

Either this interface doesn't let you see that they failed or it's not working. API response is "submitted_for_settlement".

Multi-tenancy support / dynamically set merchant id, public key, private key, etc?

I'm currently setting my Braintree merchant_id and public/private keys in a 'braintree.rb' file in config/initializers:

Braintree::Configuration.merchant_id = Rails.application.secrets.braintree_merchant_id Braintree::Configuration.public_key = Rails.application.secrets.braintree_public_key Braintree::Configuration.private_key = Rails.application.secrets.braintree_private_key

This works fine for a single-tenant application. For multi-tenancy, I'm storing this data in the database (with the private key encrypted), like a couple of other integrations my software uses. For example, for Mailgun, I'm setting the account specific info (API Key, etc) dynamically when sending mail.

Is there any way to dynamically set the Braintree configuration keys instead of setting it once/application wide/in an initializer?

Update Ruby to 2.3.1

Hi,

First, thumbs up for the good work!

Second, I just tested your example, and it worked with ruby 2.3.1 without any visible issues. Do you think we can update it within this example project?

Error handling code should be improved

This example doesn't do a great job at handling all situations where an error would occur.

This is the code that I ended up creating myself: https://gist.github.com/gregblass/33c92a58187450c82f1eba4e144c680f

I get the whole notion of 'We leave it up to the user to implement the details of error handling.' And that partially makes sense - you may want to show the error code, or not - or write your own messages for certain responses.

However, the issue is that figuring out all the different ways an error could occur takes a decent amount of time to figure out. The documentation is good, but you've still got to read through it all and put together all the different ways a payment could fail.

The SUCCESS_STATUS stuff would have been completely lost if not for this example. But then this example repo doesn't handle any verification failures. So I think this helps to unify things.

Braintree devs - feel free to take this and implement something similar into the example. Something like this would have really helped me and saved me a lot of time.

Problem integrating with IOS client.

Hi, I'm trying to implement this server with a iOS client following the braintree docs

For some reason I don't succeed and I'm not sure why.

is there anything else I need to implement in the clone I made from this repository beside .env implementation ?

This is my iOS contoller :

import UIKit
import Braintree
import BraintreeDropIn

class ViewController: UIViewController {

var paymentMethod : BTPaymentMethodNonce?

override func viewDidLoad() {
    super.viewDidLoad()
    fetchClientToken()
    // Do any additional setup after loading the view, typically from a nib.
}


func fetchClientToken() {
    // TODO: Switch this URL to your own authenticated API
    let clientTokenURL = NSURL(string: "http://localhost:3000/client_token")!
    let clientTokenRequest = NSMutableURLRequest(url: clientTokenURL as URL)
    clientTokenRequest.setValue("text/plain", forHTTPHeaderField: "Accept")
    
    URLSession.shared.dataTask(with: clientTokenRequest as URLRequest) { (data, response, error) -> Void in
        if let err = error {
            print(err.localizedDescription)
            return
        }
        let clientToken = String(data: data!, encoding: String.Encoding.utf8)
       
        self.showDropIn(clientTokenOrTokenizationKey: "sandbox_t45fvztb_245nc5pjv2tyt3n8")
        // As an example, you may wish to present Drop-in at this point.
        // Continue to the next section to learn more...
        }.resume()
}

func showDropIn(clientTokenOrTokenizationKey: String) {
    let request =  BTDropInRequest()
    let dropIn = BTDropInController(authorization: clientTokenOrTokenizationKey, request: request)
    { (controller, result, error) in
        if (error != nil) {
            print("ERROR")
        } else if (result?.isCancelled == true) {
            print("CANCELLED")
        } else if let result = result {
            // Use the BTDropInResult properties to update your UI
            // result.paymentOptionType
            // result.paymentMethod
            // result.paymentIcon
            // result.paymentDescription
        }
        controller.dismiss(animated: true, completion: nil)
    }
    self.present(dropIn!, animated: true, completion: nil)
}

func postNonceToServer(paymentMethodNonce: String) {
    // Update URL with your server
    let paymentURL = URL(string: "http://localhost:3000/client_token/payment-methods")!
    var request = URLRequest(url: paymentURL)
    request.httpBody = "payment_method_nonce=\(paymentMethodNonce)".data(using: String.Encoding.utf8)
    request.httpMethod = "POST"
    
    URLSession.shared.dataTask(with: request) { (data, response, error) -> Void in
        // TODO: Handle success or failure
        if (error != nil) {
            print(error?.localizedDescription)

        }
        }.resume()
    
}

@IBAction func pay(_ sender: UIButton) {
    postNonceToServer(paymentMethodNonce: "fake-valid-nonce")
}

}

This is my server log :

Using example produces race condition with loading script

Copy / pasted from this example into our app. Get a race condition where the braintree script is not loaded before it is called. Here's the code from this example repo that I'm suspicious of:

<script src="https://js.braintreegateway.com/web/dropin/1.9.4/js/dropin.min.js"></script>
<script>
  var form = document.querySelector('#payment-form');
  var client_token = "<%= @client_token %>";
  braintree.dropin.create({

Seems like a race condition that would always exist in this example repo... ?

Issue description

TLDR;
Root issue: Drop In UI does not load in Safari but does in Chrome

Long Version:
Was having issues with the Drop In UI in my rails app not loading (populating the bt-dropin div), cloned and started up your example (this repo) and was having the same issue.

Thought maybe it was a browser issue, sure enough works exactly as expected in Chrome, both for the example and my app.
