When Zapier hits its limits and your tools don't talk, we build the middleware. REST APIs, webhooks, custom scripts, and real-time sync — engineered for reliability.
No-code automation tools handle 80% of integration needs. The remaining 20% — and usually the most important 20% — requires actual engineering: custom APIs, webhook handlers, data transformation logic, error recovery, and rate limit management.
We build this layer. Whether you need Tally to sync with Shopify, a custom ERP to feed your CRM, or a proprietary POS system to power your marketing automation, we engineer integrations that run reliably at scale.
Our API work includes design, authentication (OAuth, API keys, JWT), versioning, rate limiting, queuing, error handling, logging, and monitoring. It's built to a production standard — not duct-taped together.
Every engagement comes with these core deliverables. No surprises, no "that's extra" conversations.
API integration architecture document
Custom-built middleware or integration scripts (Node.js / Python)
OAuth / API key / JWT authentication handled securely
Rate limit management and exponential backoff retry logic
Error logging and alerting via Sentry / Datadog / Slack
Data transformation and mapping layer
Full code handover with documentation
Deployment to your infrastructure or ours (AWS, Vercel, Railway)
30–90 days of post-launch monitoring and support
Here is the range of outcomes we design towards. Actual results vary significantly by business, scale, and execution.
If it has an API or can send a webhook, we can integrate it — including legacy systems.
Bi-directional updates in seconds, not hourly batches.
High uptime with error recovery, logging, and monitoring.
You own the code. No vendor lock-in. No per-operation costs.
We audit both systems' APIs, data models, and authentication methods.
Written architecture doc covering data flow, error handling, and deployment strategy.
Middleware built in sandbox, tested with production-like data volumes and edge cases.
Deployed to your infrastructure. Monitoring and alerts configured. Code handed over.
Final pricing depends on scope, tool count, and integration complexity. Every engagement is quoted fixed-scope after discovery.
A furniture manufacturer used a custom ERP, Shopify for their consumer line, and Tally for accounting. All three had critical data — none of them synced. Monthly reconciliation took 20 hours.
Built a Node.js middleware deployed on AWS Lambda that receives webhooks from each system, transforms data, and updates the others in real-time. Includes error recovery, audit logging, and a manual review queue for edge cases.
