Chase Payment API integration that works on launch day
Your team should sell, not debug payment webhooks. We handle the full Chase Payment integration from API credentials to PCI-compliant go-live. Your platform processes payments reliably from day one.

The difference between a working Chase connector and a broken one
Most teams find Chase Payment integration problems after go-live. Real orders fail. Real revenue disappears. Here is the difference between a botched setup and a reliable one.
Your dev team figures out Chase docs on their own
Credentials, sandbox keys, and webhook URLs get set up manually. Mistakes surface weeks later in production.
Webhooks fail silently in production
Orders process but payment confirmations never arrive. Fulfillment ships product for unpaid orders.
Retry logic is missing or wrong
Declined cards create duplicate charges or abandoned orders with no automated recovery path.
PCI compliance reviewed after launch
Security gaps found in post-launch audit. Expensive remediation or platform-level fines.
Platform-specific integration architecture
We map Chase Payment's API to your exact platform before writing a line of code. Shopify, BigCommerce, headless, or custom builds all get a tailored architecture.
Webhook reliability validated in staging
Every webhook event gets tested against real order flows before production. Authorization, capture, refund, and dispute events all pass or we do not ship.
Retry and recovery logic built in
Declined transactions trigger intelligent retry flows. Customers get a recovery path. You retain the revenue.
PCI compliance built into the architecture
Tokenization, TLS configuration, and data-handling policies reviewed before go-live. No post-launch surprises.

What a production-ready Chase payment connector looks like
After Redefine completes your Chase Payment connector, your team gets this live monitoring view. Every transaction, status, and edge case stays visible and handled.

Everything included in your Chase payment integration
This is not just an API key connection. We build payment infrastructure that handles declines, retries, refunds, and chargebacks before your customers notice a problem.
Average time to go-live from signed statement of work
Webhook delivery rate across all environments
Compliance-ready architecture included at no extra charge
Declined transactions recovered via retry logic
API Credential Setup
Sandbox and production API keys get configured and stored securely. We test every key against real Chase sandbox transactions. No production traffic hits your platform until testing passes.
Webhook Architecture
We build handlers for every Chase webhook event: authorization, capture, refund, dispute, and chargeback. HMAC signature verification runs on every inbound event. No spoofed or fraudulent data gets through.
Retry and Recovery Logic
Soft declines, network timeouts, and insufficient-funds errors trigger automatic retries. Customers get a recovery prompt instead of an error page. You keep revenue that would otherwise become an abandoned cart.
Tokenization and PCI Scope Reduction
Card data never touches your server. We set up Chase's hosted payment fields or JavaScript SDK to tokenize cardholder data before it leaves the browser. Your PCI scope stays minimal. Your audit stays clean.
Idempotency and Duplicate Prevention
Idempotency keys on every API call prevent double-charges during network failures or browser refreshes. Each payment confirmation processes exactly once, no matter how many retries fire.
Technical Handoff Documentation
You get a full API map, webhook event schema, environment variable reference, and operational runbook at handoff. Your internal team can extend, debug, or reassign the integration without relearning the codebase.
What this integration delivers at $70M+ in annual revenue

Large-Scale Home Furnishings Retailer
Ecommerce · Multi-ChannelDirect-to-consumer retailer of window coverings and home textiles operating across multiple sales channels including web, phone, and marketplace: all requiring a unified payment processing layer.
The problem
Fragmented payment processing across channels created duplicate charges, untracked refunds, and missed revenue. Their fabric calculators and special-order pricing needed custom payment gateway logic. Standard connectors could not handle it.
Solution
Redefine built a custom payment gateway integration with per-channel routing logic. We added automated billing workflows and a fully reconciled transaction ledger connected to their ERP. Every payment event became visible in real time.
Results
Annual revenue reached after integration and platform overhaul

Duplicate payment events after idempotency implementation
Transaction visibility across all channels via enterprise resource planning integration
"Our previous setup could not handle our custom pricing across channels. Redefine's integration fixed that and gave us real-time visibility into every transaction. We stopped losing revenue overnight."

Integration work done right the first time
Most integration partners treat a payment connector as a checkbox. We treat it as revenue infrastructure. One failed webhook in production costs you real money, not just a support request.
What teams ask before starting a Chase Payment integration
Most Chase Payment integrations go live in 10 to 14 business days. The timeline starts from your signed statement of work. The timeline includes API credential setup, sandbox testing, webhook implementation, user acceptance testing, and your team's final sign-off. Complexity factors like custom pricing logic, multi-currency, or enterprise resource planning reconciliation add 3 to 5 days.
Yes. Every integration starts in Chase's sandbox environment where we run full transaction scenarios: successful payments, declines, partial refunds, chargebacks, and webhook edge cases. Production credentials are only configured after all sandbox tests pass. You never go live on untested code.
Redefine integrates Chase Payment with Shopify, BigCommerce, headless ecommerce architectures (Next.js, Node.js), and custom .NET or PHP platforms. The integration approach differs by platform. We never use a one-size-fits-all connector. Your platform's order management, checkout flow, and event system all factor into how we architect the integration.
The integration includes automated retry logic for recoverable failures: soft declines, network timeouts, and temporary gateway unavailability. Hard failures (hard declines, card-not-supported) trigger a customer-facing recovery prompt. Every failure is logged with full event context, so your team can diagnose the issue without digging through raw API logs.
You need an active Chase merchant account and API access before integration begins. If you are mid-application with Chase, we can start scoping the integration in parallel and begin sandbox work using test credentials. The production go-live waits for your approved merchant account. We do not manage the merchant onboarding process with Chase. But we can tell you exactly which credentials to request.
