WARNING: Can't verify CSRF token authenticity in case of API development
You can do this by adding
skip_before_filter :verify_authenticity_token
to your controller. This way all incoming requests to the controller skips the :verify_authenticity_token filter.
For rails 4 it should be
skip_before_action :verify_authenticity_token, only: [:one_or_two_actions_here]
Note that you should avoid skipping verify_authenticity_token on all actions of your controller, instead use the option only to skip only where you have to. See the docs
