Base Amount: Enters a numeric value as the minimum price accepted.
PayPal product name: The name of the product displayed on PayPal. It is possible to define the product’s name through a field in the form, you only should enter a special tag with the format: <%fieldname#%>, for example, if the product name is defined through the fieldname1 field, the special tag would be: <%fieldname1%>
PayPal language: Enter the language code to use in the PayPal interface (Please, CLICK HERE to get the complete list of language codes)
PayPal frequency: This attribute allows a greater versatility with the payment gateway, the possible options are:
- One time payment, the user is billed only once
The rest of the options allow to define recurrent payments.
- Bill the user every 1 month
- Bill the user every 3 months
- Bill the user every 6 months
- Bill the user every 12 months
If you want to define recurring payments with a different interval, maybe 2 or 4 months, or if you want that the user select its own frequency, select the latest option:
- From field
In this case would be required select the field in the form that defines the payments frequency (only accepted “Radio”, and “DropDown” fields). You should take this field into account to define the final amount for billing because the frequency would be selected by the user.
Tip: The maximum period supported by PayPal is for 12 months.
For the recurring payments it is possible define a first payment, different to the recurring payments (there are many services that require an initial payment bigger than the recurring payment), and a grace period, for deferring the first payment by a number of days, that in many services is used as the trial period.
Additionally the PayPal section includes attributes to define discount coupons to reduce the final amount to pay.
Q: Can the users pay directly with their Credit Cards, without a PayPal account?
A: The answer to this question depends from PayPal. In function to your PayPal account, and your country, it is possible to charge the quote to the customers, directly from their Credit Cards. Please, contact to the PayPal support to know if your account accepts this behavior.
