The Braintree extension for Magento 1 works out-of the box with the latest Magento responsive default checkout and has been integrated with the most popular checkout extensions from:

- MageCheckout

- MageStore (3.5.0)

- IWD (4.2.2)

- Awesome Checkout (1.5.0)

- OneStepCheckout (iDev) (4.5.8 as of v3.0.0 of Braintree)

- AheadWorks (1.3.11 as of v3.0.0 of Braintree)

- FancyCheckout (1.2.6)

- Fire Checkout (3.8.0)

- Unicode

- Amasty Checkout (3.2.2 as of v3.0.0 of Braintree)

Whilst we have made every effort to provide integration files for the popular checkout solutions - if bespoke customisation work has taken place on your store's checkout we cannot guarantee the extension will work out of the box and are unable to provide support in such instances.
