Shopify Checkout.com integration for higher approval rates and fewer declines
Connect Shopify or Shopify Plus with Checkout.com to route card payments smarter, cut false declines, and keep fraud controls, reporting, and payouts in one place.

Seeing payment failures in Shopify is frustrating because the root cause is often buried across gateways, 3DS checks, and issuer responses. Meanwhile, fraud rules, retries, and refunds get handled in separate places, and your team ends up chasing chargebacks or reconciling payouts after the fact.
The Shopify – Checkout.com integration connects your storefront checkout to Checkout.com’s payment processing so authorizations, captures, refunds, and payment status updates flow through one path. It keeps order payment states consistent between Shopify and Checkout.com, so finance and support work off the same source of truth when investigating declines, disputes, or settlement questions.
This setup fits if you run Shopify at a scale where payment performance, fraud controls, and reconciliation need tighter handling than a basic gateway flow.

• Checkout.com is used as the payment gateway in Shopify checkout, routing card payments through Checkout.com APIs and returning authorization outcomes to Shopify.
• Shopify order and payment identifiers are linked to Checkout.com payment IDs, allowing captures, voids, and refunds to be correlated across both systems.
• Payment lifecycle events (authorized, captured, refunded, failed) are propagated back to Shopify via webhooks or status callbacks, updating the order financial status.
• 3DS authentication outcomes and soft decline responses are handled within the Checkout.com flow, with final success or failure posted back to Shopify.
• Partial and full refunds initiated in Shopify are translated into Checkout.com refund requests, and resulting refund statuses are synchronized back to the order.
• Transaction metadata, currency, and amount precision are validated to match Shopify totals, with errors logged for mismatches and rejected callbacks.

Why choose scandiweb to handle Shopify integration for you?
How does the Shopify Checkout.com integration handle authorizations, captures, and refunds?
Checkout.com processes the card payment, and Shopify receives the resulting status for the order. Captures and refunds can be routed so both systems stay aligned on what was charged and returned.
Can Checkout.com send real-time payment status updates back to Shopify for support and finance teams?
Yes, webhooks can push events like authorized, captured, refunded, and failed into Shopify. This reduces manual checks when investigating declines, disputes, or settlement timing.
Does a Shopify Plus Checkout.com integration support 3DS and SCA for EU and UK payments?
Yes, Checkout.com supports 3DS flows required for SCA, and the integration can be configured to apply it based on region, risk, and card type. The goal is compliance without forcing 3DS on every transaction.
Can Checkout.com help reduce false declines and improve payment acceptance on Shopify?
Often, yes – acceptance can improve when routing rules, retries, and 3DS logic are tuned to your traffic and issuer patterns. We validate changes with clean tracking so you can see approval rate movement, not guesses.
How hard is it to migrate from another payment gateway to Checkout.com on Shopify without revenue loss?
Migration is usually a phased switch with parallel testing, monitoring, and rollback options. scandiweb has delivered 2,100+ eCommerce projects since 2003, so we plan go-live around risk, not convenience.
