The new Payment Gateway field lets you enable multiple payment options in one place, including Square, PayPal, Mollie, Authorize.Net, Stripe, and Razorpay. This allows users to choose their preferred payment method and pay the amount configured in your form.

For Mollie payments, customers can securely complete transactions using credit/debit cards, bank transfers, and other supported local payment methods. When a visitor selects Mollie and submits the form, they are redirected to a secure Mollie checkout page to finish the payment and then returned to your site. All transactions are processed safely through Mollie, allowing you to accept both one-time and recurring payments depending on your setup.

3. Click the Payment Gateway field to open its settings on the left.
4. In the Gateways section, make sure the Mollie toggle is turned on.

Add what you’re charging for

Set the price on a single item. You can customize it even further by changing its features. Choose between Field to fit your payment forms better

Field	Use it when…
Single Item	You’re selling one product or service at a fixed price
Single Item (User Defined)	You want visitors to enter their own amount — great for donations
Multiple Choice	Visitors pick one option from a list (e.g. Small, Medium, Large)
Checkbox	Visitors can select more than one item at the same time
Subscription Plan	Visitors choose a recurring billing plan (monthly, yearly, etc.)
Total	Shows the running total of everything selected — always add this for multi-item forms

Accepting a One-Time Payment #

For a simple payment form — like selling a product or accepting a donation — here’s all you need:

1. Add the Payment Gateway field and make sure Mollie is turned on.
2. Add a Single Item field and set your price.
3. Add a Total field so visitors can see what they’ll be charged.
4. Add an Email field — Stripe needs an email to send the payment receipt.

Send Extra Customer Details to Mollie #

3. Alternatively, copy the shortcode located beside the Save button, then add a Shortcode block to any page and paste the shortcode into that block.
