Before you take payments online, decide which processor you'll use and how strictly to check card addresses.

Supported processors

Certain works with Authorize.Net, Chase Orbital, Cybersource, Pay.gov, PayPal, PayPal - Connect, Shift4 (hotel room guarantees only) and Stripe - Payment Intents. Stripe and PayPal accounts can also be connected under Connected Stripe Accounts and PayPal Seller Onboarding. See E-commerce Account Details

An e-commerce account is available to every event and form in the account it belongs to.

Turning on online payments for an event

1. Make sure the Financial module, with E-commerce, is turned on for your account under Account Settings > Implementation > Products.
2. Pick the processing account for the event under Plan > Event Setup > Financials.
3. On each form that takes payments, go to Payment and check Process payments online for this form.
4. Make sure the form's page layout includes the Payment section.

Deciding how to check card addresses

Address checks (AVS) compare the billing street number and zip code a registrant enters with what the card issuer has on file. The bank answers Y (match), N (no match) or X (the issuer doesn't support the check). The bank only gives advice. Your settings decide whether Certain accepts or rejects the card.

• Collect Billing Address: asks for a billing address, which address checks need.
• Match Zip Code: checks the zip code.
• Match Street Number: checks the street number. 123 Main St. and 123 Howard Ave. give the same result.
• Require AVS "Yes" Response: rejects cards from banks that don't support the check (X).

To avoid tying up a registrant's credit limit with failed attempts, Certain first runs a $0.01 authorization to get the address result, then voids it right away. If the result passes your settings, Certain charges the full amount. If it doesn't, the registrant sees an error (code 112). Even so, some card issuers hold the $0.01 for a while.

When Require AVS "Yes" Response is off

• Match Zip Code only: accepts Zip Y or X, rejects Zip N. Street is ignored.
• Match Street Number only: accepts Street Y or X, rejects Street N. Zip is ignored.
• Both checked:

When Require AVS "Yes" Response is on

• Match Zip Code only: accepts Zip Y, rejects Zip N or X. Street is ignored.
• Match Street Number only: accepts Street Y, rejects Street N or X. Zip is ignored.
• Both checked:

These settings are on the e-commerce account and on each event under Plan > Event Setup > Financials, in Online Payment Security Options. Changing the account doesn't change events and forms that already have them.

Next step: Set up your e-commerce account, then run a test payment.
