Rails 4 solution for "Can't verify CSRF token authenticity” json requests

application_controller.rb

class ApplicationController < ActionController::Base
    protect_from_forgery with: :null_session,
      if: Proc.new { |c| c.request.format =~ %r{application/json} }
end

Thanks for this solution though it has been 8 years already, this helped me finish off my tinkering task (I'm not a backend guy nor a RoR guy.).
I am currently using Rails 7.0.3.1.
The rails app connected to Braintree was throwing me this error: Can't verify CSRF token authenticity - this gist is the answer.

i was struggling this error "Can't verify CSRF token authenticity" since long time. Thank you so much for this solution.
