High Risk Payment Gateway Integration
Kashberg connects your high risk payment gateway to your store: custom integrations for US merchants that mainstream processors and standard plugins turn away. Your processor, your rules, a checkout that works.
What we do
Getting approved for a high risk payment gateway is only half the job. Most high risk processors have no plugin for your store, an outdated one, or one that cannot handle your payment rules. That is where orders get lost, payments stop matching orders, and customers leave at the payment step.
We connect the processor you are approved with to your store properly: a custom gateway integration, payment rules that depend on what is in the cart, a backup processor when one declines, and payments that always match your orders. We are a US company working US business hours, and we have been building checkouts for high risk merchants in the US and Canada since 2020.
Who this is for
Merchants in categories mainstream processors restrict, such as CBD, supplements, vapes, subscriptions and other regulated products, selling on WooCommerce or a custom store, who need their checkout to work with a specialist processor.
Problems we fix
- Three processors have declined the account, and the fourth has no plugin for the store.
- The processor's plugin is years out of date and breaks whenever WooCommerce updates.
- Every payment method shows to every customer, even where some of them cannot be used for that order.
- Paid, pending and failed payments do not match the orders, so someone checks them by hand.
- There is one processor and no backup, so a frozen account stops all sales.
What we build
- Custom payment gateway integrations for high risk and specialist processors that off-the-shelf plugins do not support.
- WooCommerce high risk payment gateways: a gateway plugin built for your processor and your store, and maintained after launch.
- Conditional payment logic: rules that decide which payment methods each customer sees, by product, cart value, country or order type.
- Multiple processors with automatic fallback, so a decline or a frozen account does not stop every sale.
- Multi-currency and multi-language checkouts, including regulated product copy in each language.
- Payment webhooks and reconciliation, so every payment is matched to its order without anyone checking by hand.
How it works
Free call
A 30 minute call about your store, your processor and what is going wrong today. You get an honest view of what it takes.
Plan
We review your processor's API and your checkout, then split the work into phases with a clear estimate for each before anything starts.
Build
We build the gateway, the payment rules and the checkout changes on a staging copy of your store, with weekly testable builds.
Test every payment path
Successful, declined, refunded and partially refunded payments, webhooks and currency changes are all tested before anything goes live.
Launch and maintain
We launch with you, watch the first orders, and keep the integration updated when your store, your platform or your processor changes.
We are not a payment processor or a bank, and we do not approve merchant accounts. You apply to the processor of your choice; we build and maintain the integration that connects it to your store, and we can talk you through what processors usually ask for.
Questions we get
Are you a payment processor?
No. We do not process payments or approve merchant accounts. You choose and apply to a high risk processor, and we build the integration that connects it to your store, then maintain it.
Do you offer custom payment gateway development?
Yes. When a processor has no plugin for your store, or its plugin cannot handle your rules, we build the gateway from the processor's API: payments, refunds, webhooks and order updates, all tested before launch.
Which platforms do you build high risk gateways for?
Mostly WooCommerce, where we build a custom gateway plugin for your processor, and custom stores built with React, Next.js or Laravel. If you are on another platform, tell us on the free call and we will say plainly whether a custom gateway is possible there.
Can you add a backup processor?
Yes. We can connect more than one processor and route payments between them, by rules you choose or automatically when one declines. For a high risk business, a single processor is a single point of failure.
Do you work with CBD payment processing and other restricted products?
Yes. Cannaffex, a Canadian CBD brand, had been declined by three processors before we built their custom gateway, conditional payment logic and bilingual checkout. It has been live since 2023.
Does card data pass through our server?
Where the processor supports it, we use its hosted payment fields or tokens, so card numbers go straight to the processor and never touch your server. That keeps your security and compliance work much smaller.
How long do your payment gateway integration services take?
A gateway integration is a smaller project than a full platform. After the free call we give you a clear estimate for each phase, and you see a working build on a staging copy of your store before anything goes live.
