WooCommerce payment fix

Payments are failing. Orders aren't completing.

A WooCommerce payment failure means real orders lost in real time. Whether it's Stripe throwing errors, PayPal redirecting nowhere, or your gateway silently rejecting cards — we find it and fix it.

By gateway

We fix payment failures across every major gateway

Each gateway fails differently. Stripe webhook errors need a different fix to a PayPal IPN problem. We know all of them.

Stripe

Webhook mismatches, SCA/3D Secure rejections, live/test mode confusion, currency mismatches, and API key expiry are the most common Stripe issues in WooCommerce.

PayPal

IPN not firing, orders stuck pending after PayPal redirect, currency not supported, and sandbox credentials left on production are the most frequent PayPal failures.

IPN_FAILUREPAYMENT_DENIEDCURRENCY_NOT_SUPPORTED

WooPayments

Account verification failures, WPCOM connection errors, and dispute handling issues. WooPayments is tightly coupled to WordPress.com — connection faults are common after migrations.

Square

OAuth token expiry, location ID mismatches, and currency/region restrictions cause most Square failures in WooCommerce. Often triggered by a password change on the Square account.

AUTHENTICATION_ERRORINVALID_LOCATION

Klarna / Clearpay

BNPL gateways have strict eligibility rules and API version requirements. Failures are often caused by outdated plugin versions or merchant account configuration issues.

Other gateways

Sagepay, Worldpay, Opayo, Authorize.net, and others — we work with all major gateways. If it connects to WooCommerce, we can diagnose it.

The process

How we diagnose and fix it

Payment failures leave traces — in error logs, webhook logs, and gateway dashboards. We follow the evidence.

Tell us what's failing

Which gateway, what error message, and when it started. We'll also need WordPress admin and hosting access to begin the diagnostic.

⏱ 5 minutes

We trace the failure

We check gateway logs, WooCommerce error logs, webhook endpoints, API credentials, SSL status, and plugin compatibility — working from the payment attempt backwards to the root cause.

⏱ Same day

Fixed and tested live

We fix the root cause, run a live transaction test, and verify the order completes end-to-end — including the confirmation email. Written summary of what we changed and why.

Real fix · 2026

Stripe webhook broken after a hosting migration

A health supplements retailer migrated to a new host and immediately saw payment failures. Cards were being charged by Stripe but orders weren't completing in WooCommerce — customers were paying and getting nothing.

Diagnostic trace

→ Stripe dashboard payments succeeding ✓

→ WooCommerce orders stuck on pending

→ Stripe webhook log delivery failures

→ Webhook endpoint URL

→ Error: HTTP 301 — old domain still in Stripe webhook config

✓ Root cause: webhook URL not updated in Stripe after domain change

The migration changed the site domain but the Stripe webhook endpoint still pointed to the old URL. Stripe was sending payment confirmations to a domain that no longer existed. Orders never updated. We updated the webhook, regenerated the signing secret, and verified end-to-end order completion.

FAQ

Customers have been charged but orders haven't completed. What do I do?

Don't refund manually yet — the order data may be recoverable. This is usually a webhook failure, meaning the payment went through but WooCommerce never received confirmation. We can often replay the webhook and complete the orders without any customer impact. Contact us immediately.

My gateway worked fine yesterday — what changed?

Payment failures that appear overnight are usually triggered by a plugin update, a hosting change (new domain, new SSL cert, PHP version bump), or an API key rotation on the gateway side. We'll trace which change caused it.

Is this a Stripe / PayPal problem or a WooCommerce problem?

Usually WooCommerce-side — the gateway is receiving requests but something in the configuration, plugin, or hosting environment is preventing proper communication. If it genuinely is a gateway platform outage, we'll confirm that quickly and you won't be charged.

Can you help recover orders that are stuck on pending?

Yes — recovering stuck orders is included in the Priority fix. Once we've fixed the root cause and the webhook is working, we can trigger a replay of failed webhook events to complete the pending orders automatically.

Do you work with Shopify payment issues too?

Yes. For Shopify we cover third-party gateway configuration, app conflicts affecting payment processing, and Shopify Payments setup issues. Core Shopify Payments infrastructure issues are managed by Shopify directly.
