API Development & Integration Services
Disconnected systems force teams to re-key data by hand, and third-party APIs break integrations without warning. Kodexo Labs closes that gap with API development and integration services, building custom REST and GraphQL APIs that connect the systems you already run. Extensiv's operations team now queries four databases in plain English.

TRUSTED BY ENTERPRISES
This is not GenAI bolted onto a product, and it is not a data-platform rebuild. It is the connective layer that keeps your applications, databases, and third-party services exchanging clean, current data reliably.
What our API development and integration work covers:
Custom REST and GraphQL APIs designed, documented, and built to spec.
Third-party and SaaS integrations for Salesforce, Stripe, and Twilio.
Real-time, event-driven data pipelines using webhooks, WebSockets, and gRPC.
Custom enterprise API integration that connects legacy systems to modern tools.
API security with OAuth 2.0, JWT, rate limiting, and versioning.
Monitoring that catches broken endpoints before your customers ever notice.

What Our API Development and Integration Work Covers
Most integration projects stall in the gap between systems that were never built to talk. We build the APIs, connectors, and governance that close it, then keep data moving after launch, not just during the demo.
RESTful API Architecture & Development
Your app is only as good as the API under it. We design and build RESTful APIs, documented in OpenAPI, that systems trust.
Clean APIs that send back the right data in the right shape, every time.
Every route is mapped, so your team and ours read the very same contract.
Your Systems Are Not Talking to Each Other

Roadmaps That Shipped Results
Diesel Laptops
Fleet technicians lost minutes on every job hunting through 160,000 parts records. Solution: Kodexo Labs built an AI parts-lookup running inside their own self-hosted AWS VPC, keeping all data on their private cloud. Outcome: lookup time fell 85%, so a technician finds the right part in seconds, not minutes, on every daily job.

Extensiv
This $130M-funded logistics platform had operations staff waiting on engineers for every data question spread across 4 databases. Solution: Kodexo Labs built a LangGraph agentic system that reads plain-English questions and answers them directly. Outcome: staff now query 207 tables themselves, at over 90% accuracy, with answers arriving in seconds instead of days.

Zendrop
Zendrop's product teams were stuck in a slow, expensive launch cycle on their existing SaaS platform. Rather than rebuild the whole product from scratch, we added an AI-driven automation pipeline to the platform they already ran. Time-to-market dropped 45%, launch costs dropped 50%, and buyer conversion rose 25%. Zendrop is a VC-backed ecommerce platform.

API Integration Built for the Systems Your Industry Runs
A silo in healthcare is not the same problem as one in logistics. HIPAA governs one; siloed warehouse tables stall the other. We shape every API and integration around the systems and rules your sector runs on.

Why Teams Choose Kodexo Labs to Build Their APIs and Connect Their Systems
Anyone can connect two systems once. The hard part is doing it reliably, at volume, under compliance, without breaking when a vendor changes an endpoint. The four things below are why clients trust us there.
Agentic Self-Serve API Layers
Extensiv's ops team had to ask engineering for each data question. Kodexo Labs built an API in LangGraph that turns plain English into answers from the live database. Now the team can self-serve.
Self-Hosted for Sensitive Data
Diesel Laptops needed search that never left its own network. Kodexo Labs built a RAG search API and ran it inside the client's own AWS VPC, reading 160,000 records with no outside calls.
Real-Time Vendor Data Pipelines
Each vendor sends data in its own shape, on its own clock. Kodexo Labs built event-driven webhooks that ingest and clean vendor APIs as the data changes. Zendrop cut launch costs by 50%.
Legacy API Integration, Rebuilt
IFPG's chatbot API broke on 1,000+ franchise listings. Kodexo Labs rebuilt the reasoning layer so that its answers came back clean. Broken replies fell to zero and accuracy rose 85% for the network.

Overcoming API Development & Integration Challenges
Most API projects fail for a few predictable reasons. A legacy system nobody can connect to. A vendor endpoint that changes overnight. Vendor data in five different shapes. Here is how our API development and integration services solve each one.
Every tool listed is in active production on a Kodexo Labs.
Every framework, runtime, and cloud service named here is running on a live client product right now. No theoretical stack, no resume keywords, no tools added for marketing weight.
Our API Development and Integration Delivery Process
No black box. Five phases, clear checkpoints, and working APIs you can test at every stage before the next one begins.
Discovery & API Audit
We start with your real systems, not a template. We map every data source, every third-party API, every legacy database, and the compliance rules that apply, before we design a single endpoint.
API Architecture & Design
Next we design the architecture: REST or GraphQL, the OpenAPI spec, how services connect through microservices architecture and middleware, and where data lands. Our custom API integration services trace every choice to a named system.
Development & Integration Build
Now we build. We stand up the APIs, wire the connectors, and integrate each system in sprints, with a working endpoint demoed every week so you see progress you can test, not status slides.
Testing, Security & Compliance Validation
Before launch, we validate. Every endpoint is load-tested, error handling and recovery get exercised under traffic, and security is checked against OAuth 2.0, SOC 2, HIPAA, GDPR, and PCI-DSS, one framework at a time.
Deployment, Monitoring & Continuous Support
At go-live we deploy with monitoring already running. Rate limiting, anomaly alerts, and versioning are live from day one, and we keep tuning performance and endpoint reliability long after real traffic arrives.
