Mollie Payments 1.0.2

Accept PayPal, credit cards, SEPA, and more directly through Mollie.

Seamlessly integrate Mollie into XenForo’s built-in payment system. This add-on adds Mollie as a first-class payment provider for user upgrades, subscriptions, and one-time payments, giving you a modern, reliable alternative to PayPal or Stripe.

Features​

• Full Mollie integration – Supports all Mollie methods available on your account; credit card, iDEAL, Bancontact, PayPal, Sofort, Giropay, and SEPA direct debit (beta)
• One-time & recurring billing – Works with XenForo’s native user upgrade system, supporting both single payments and renewable subscriptions.
• Automatic subscription handling – Recurring payments are linked to Mollie subscriptions. First-time mandates are handled cleanly, with upgrades automatically extended when payments clear.
• Refunds & chargebacks – If you issue a refund or receive a chargeback in Mollie, the user’s upgrade is automatically downgraded in XenForo. Partial refunds are logged without removing access.
• Idempotent & reliable – Webhooks and replays are fully idempotent, ensuring payments are only processed once (no accidental double-extensions).
• Webhook security – Supports Mollie’s signing secrets for webhook validation.
• XF 2.2 and 2.3 compatible – Works on both PHP 7.4+ (XF 2.2) and PHP 8.1+ (XF 2.3), with compatibility for legacy cURL and modern Guzzle stacks.
