Accept Klarna
payments on J2Commerce
Install the free PaymentHood plugin for J2Commerce, connect your Klarna account, and Klarna appears as a payment option at checkout. No custom gateway code, and no second integration when you add another provider later.

- One-time checkout payments. Recurring billing is not supported by the J2Commerce plugin yet.
- Cost
- The plugin is free and open source. You pay Klarna's own fees, published on their pricing page (opens in new tab). PaymentHood adds nothing on top.
Coverage, currencies and payment methods as published by Klarna, who set and update them. For the current list see Klarna's own documentation (opens in new tab).
What J2Commerce customers can pay with
Each method Klarna supports appears in your J2Commerce checkout. Enabling one is a PaymentHood dashboard setting — nothing changes on the Joomla side.
Pay in instalments
The order is split into scheduled payments
Pay later
The shopper is invoiced after delivery
Pay now
Immediate payment through Klarna's checkout
Connect Klarna to J2Commerce
Four steps, no code. The full walkthrough with screenshots is in the J2Commerce installation guide.
Open a Klarna account
Register with Klarna and finish their onboarding. Funds settle from Klarna to your own bank account.
Add it in PaymentHood
Paste your Klarna credentials into the PaymentHood dashboard. They stay server-side and never reach your storefront.
Install the plugin
Download the J2Commerce plugin and install it from Extensions → Manage → Install in your Joomla admin.
Enable and test
Paste your PaymentHood API key into the plugin settings, run a sandbox order end to end, then switch to live.
Rather than a direct Klarna plugin
A single-provider plugin works until you need a second provider. These are the parts you would otherwise build and maintain yourself.
- Webhook security
- Signed push notification, validated before an order is released
- Payment verification
- Server-side order status re-check against the Klarna API before fulfilment
- Credentials
- API username and password issued per market, held server-side in PaymentHood
- Add a second provider without touching your J2Commerce checkout
- Automatic failover when Klarna is unreachable, instead of a failed order
- Idempotent charge creation, so a double-submitted order is not a double charge
- One reconciliation view across every provider you run
- Free and open source — read the plugin on GitHub (opens in new tab)
