Braintree Express Example

Build Status

An example Braintree integration for Node in the Express framework.

Setup Instructions

  1. Install packages:

    npm install
  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 the server:

    npm start

    By default, this runs the app on port 3000. You can configure the port by setting the environmental variable PORT.

Deploying to Heroku

You can deploy this app directly to Heroku to see the app live. Skip the setup instructions above and click the button below. This will walk you through getting this app up and running on Heroku in minutes.


Running tests

To run unit tests, use npm run test:unit. These do not require a server and do not make API calls.

To run all tests, run npm test. This requires the server be up (in a separate shell using npm run dev or npm start) to make the relevant API calls to Braintree. npm test requires that your sandbox Braintree credentials be set up as detailed above.

Testing Transactions

Sandbox transactions must be made with sample credit card numbers, and the response of a call is dependent on the amount of the transaction.
