Many of the settings you pass in here are already factored in from the wepay.yml file and only need to be overridden if you insist on doing so when this method is called. The following list of key values are pulled in for you from your wepay.yml file:

Note: @wepay_config is your wepay.yml as a Hash :callback_uri => @wepay_config, :redirect_uri => @wepay_config, :fee_payer => @wepay_config, :type => @wepay_config, :charge_tax => @wepay_config ? 1 : 0, :app_fee => @wepay_config, :auto_capture => @wepay_config ? 1 : 0, :require_shipping => @wepay_config ? 1 : 0, :shipping_fee => @wepay_config, :charge_tax => @wepay_config, :account_id => wepay_user # wepay-rails goes and gets this for you, but you can override it if you want to.

params hash key values possibilities are: Parameter: Required: Description: :account_id Yes The unique ID of the account you want to create a checkout for. :short_description Yes A short description of what is being paid for. :long_description No A long description of what is being paid for. :type Yes The the checkout type (one of the following: GOODS, SERVICE, DONATION, or PERSONAL) :reference_id No The unique reference id of the checkout (set by the application in /checkout/create :amount Yes The amount that the payer will pay. :app_fee No The amount that the application will receive in fees. :fee_payer No Who will pay the fees (WePay’s fees and any app fees). Set to “Payer” to charge fees to the person paying (Payer will pay amount + fees, payee will receive amount). Set to “Payee” to charge fees to the person receiving money (Payer will pay amount, Payee will receive amount - fees). Defaults to “Payer”. :redirect_uri No The uri the payer will be redirected to after paying. :callback_uri No The uri that will receive any Instant Payment Notifications sent. Needs to be a full uri (ex www.wepay.com ) :auto_capture No A boolean value (0 or 1). Default is 1. If set to 0 then the payment will not automatically be released to the account and will be held by WePay in payment state ‘reserved’. To release funds to the account you must call /checkout/capture :require_shipping No A boolean value (0 or 1). If set to 1 then the payer will be asked to enter a shipping address when they pay. After payment you can retrieve this shipping address by calling /checkout :shipping_fee No The amount that you want to charge for shipping. :charge_tax No A boolean value (0 or 1). If set to 1 and the account has a relevant tax entry (see /account/set_tax), then tax will be charged.
