Question 1

How do I test payments without real charges in Braintree Ruby?

Accepted Answer

Use the free sandbox environment by signing up for a Braintree sandbox account and configuring the gateway with sandbox credentials, as shown in the quick start example. This allows you to simulate transactions safely.

Question 2

Braintree Ruby gem vs Stripe Ruby gem: which should I use?

Accepted Answer

Choose based on your payment processor: Braintree Ruby is best if you need Braintree-specific features like PayPal integration, while Stripe's gem might offer different API design. Both are official SDKs, so evaluate based on your gateway preference and pricing.

Question 3

How to handle recurring subscriptions with Braintree Ruby?

Accepted Answer

Use the subscription methods in the gateway, such as gateway.subscription.create, to set up plans and manage billing cycles. Refer to the official documentation for detailed examples on parameters and error handling.

Question 4

What are common errors and how to debug them in Braintree integration?

Accepted Answer

Check the result object for processor response codes and texts, as shown in the quick start. Use the non-bang methods to inspect errors without raising exceptions, and consult Braintree's developer docs for specific error codes.

Question 5

Is Braintree Ruby compatible with the latest Ruby on Rails versions?

Accepted Answer

Yes, it's a standard Ruby gem tested against Ruby 2.6+, so it works with Rails 7 and newer. For frontend, pair it with Braintree's JavaScript SDK for a complete payment flow.

Question 6

How to secure API keys in a Rails app with Braintree?

Accepted Answer

Store merchant ID, public key, and private key in environment variables or Rails credentials. Configure the gateway dynamically per environment to avoid hardcoding sensitive data, as recommended in security best practices.
