I’m trying to get started with the braintree gateway but without successful.
I run on self host version 4.2.2, I have put the credentials and in the test mode I have the following message .
Braintree\Exception\Authentication - It may help to set new passwords or generate new API keys.
If I give it to normal mode it will stick to the moment when I click on the payment button.
Credentials are definitely right …
There is something I still have to do ??
