ios - Braintree vault not storing payment methods -

my sandbox account doesn't store payment methods customer in vault. creating customer object using:

def create_customer   result = braintree::customer.create(     :first_name => params[:first_name],     :last_name => params[:last_name],     :email => params[:email],     :phone => params[:phone]     )   if result.success?     render :json => {'result' => result.customer.id}   else     render :json => {'errors' => result.errors}, :status => 400   end end 

and storing customer_id in database later use.

when creating client_token sending same customer_id api. here code creating client_token:

def client_token   token = braintree::clienttoken.generate(     :customer_id => params[:customer_id]     )   render :json => {"token" => token} end 

_{i work @ braintree. if have more questions integration, can get in touch our support team}

you need create payment method nonce receive client:

result = braintree::paymentmethod.create(   :customer_id => "131866",   :payment_method_nonce => nonce_from_the_client )
