Checkout prefilling

The Riseact checkout supports prefilling data via the URL query string. You can pre-populate personal fields, amount, frequency and more directly in the campaign URL.

It works both for the web checkout (direct access to the campaign URL) and for the Donation Button (embedded in a modal).

Supported parameters

Add the parameters as normal query strings to the checkout URL.

Parameter	Type	Description
amount	decimal	Preselected amount (e.g. 25.00)
frequency	integer	Frequency: 0 = one-time, 12 = monthly
legal_person	string	Type of person: INDIVIDUAL or COMPANY
first_name	string	First name
last_name	string	Last name
email	string	Email address
phone	string	Phone
mobile	string	Mobile
business_name	string	Company name (for legal entities)
ssn	string	Tax code
vat	string	VAT number
address	string	Address
city	string	City
locality	string	Province / locality

country	string	Country
supporter_id	integer	ID of an existing supporter. If provided, the personal fields above are ignored
cost_example	UUID	ID of a preselected cost example
cost_example_quantity	integer	Quantity for the cost example (must be > 0)
tags[]	array	Tags to associate with the checkout (bracket notation: tags[]=a&tags[]=b)

note

If supporter_id is set, all personal fields (legal_person, first_name, last_name, email, phone, mobile, business_name, ssn, vat, address, address2, city, locality, postal_code, country) are ignored, even if present in the URL.
