Website API Integration
Seamlessly connect your website to external CRMs, payment gateways, ERPs, marketing automation tools, and custom backend databases with resilient REST & GraphQL pipelines.
What is Website API Integration?
Isolated websites that cannot communicate with your internal business tools force your team into hours of manual data entry, lead to missed customer opportunities, and create data synchronization errors between systems.
We engineer robust, fault-tolerant API integrations. We connect your website to Stripe, HubSpot, Salesforce, QuickBooks, Zapier, custom databases, and webhook queues with automatic retries, rate-limiting handlers, and encrypted payload signatures.
Guarantees zero missed leads, duplicate charges, or lost records even during third-party service outages.
Encrypted OAuth2 token refresh pipelines and environment variable secrets management.
Instant updates between your website and your CRM, ERP, or accounting software.
What's Included in Every Project
End-to-end deliverables designed for high conversion, clean architecture, and rapid deployment.
API Architecture & Data Schema Mapping
Complete documentation of payload contracts, webhook events, and bi-directional field mappings.
Secure REST / GraphQL Integration Endpoints
Built with Next.js Server Actions, Zod validation, and secure server-side token management.
Webhook Listener & Dead-Letter Queue Engine
Fault-tolerant event queue that logs, validates signatures, and retries failed requests automatically.
Payment Gateway & Billing Integration
Stripe, PayPal, or LemonSqueezy integration with subscription webhooks and automated receipt delivery.
CRM & Marketing Automation Sync
Real-time sync with HubSpot, Salesforce, ActiveCampaign, Klaviyo, or custom internal databases.
30-Day Post-Launch Warranty & API Health Telemetry
Automated logging and alerting for API rate limits and external service errors.
Our 4-Step Delivery Process
Agile, milestone-based sprints with preview links and transparent reporting.
API Discovery & Schema Specification
We analyze external API documentation, authenticate developer keys, and map data transfer schemas.
Serverless Endpoint & Queue Build
We write strictly-typed TypeScript API client handlers with Zod schema validation and retry logic.
Sandbox Testing & Edge Case Simulation
We simulate network timeouts, invalid payloads, and high-concurrency webhook bursts in staging.
Production Deployment & Monitoring
We deploy the integration with encrypted secrets and configure Sentry error telemetry.
Technologies & Tools Used
Production frameworks, UI design systems, and deployment runtimes.
