Paypal Masspay Ruby Example
The title of this post is a Google query that yielded no good results, but plenty of puzzled users trying to figure out how to make it work. I’ve only been playing with it for about half an hour, but this code is getting Paypal to tell me that the request is successful:
def self.send_money(to_email, how_much_in_cents, options = {}) credentials = { "USER" => API_USERNAME, "PWD" => API_PASSWORD, "SIGNATURE" => API_SIGNATURE, } params = { "METHOD" => "MassPay", "CURRENCYCODE" => "USD", "RECEIVERTYPE" => "EmailAddress", "L_EMAIL0" => to_email, "L_AMT0" => ((how_much_in_cents.to_i)/100.to_f).to_s, "VERSION" => "51.0" } endpoint = RAILS_ENV == 'production' ? "https://api-3t.paypal.com" : "https://api-3t.sandbox.paypal.com" url = URI.parse(endpoint) http = Net::HTTP.new(url.host, url.port) http.use_ssl = true all_params = credentials.merge(params) stringified_params = all_params.collect { |tuple| "#{tuple.first}=#{CGI.escape(tuple.last)}" }.join("&") response = http.post("/nvp", stringified_params) end
Certainly not the tersest solution, but I’ve kept it a bit verbose to make it clearer what’s happening.
One point of note is that you’ll need separate credentials when submitting to sandbox vs. production. You can sign up for a sandbox account by clicking “Sign up” from this page. After you have your account, login, click on “profile,” then get your API access credentials.
Here is the PHP example I based my code on and here is the Paypal Masspay NVP documentation that was marginally helpful in figuring out what params to pass.
