API DESIGN & INTEGRATION SERVICES
Connect every system in your stack.
Disconnected systems are a tax on your organization. Every manual data transfer, every copy-paste between tools, every report built from five different exports — that's integration debt compounding daily. Maxx Stacks connects your systems properly: via APIs built for reliability, scale, and intelligence.
150+ CONNECTORS. CUSTOM APIS. ONE INTELLIGENCE LAYER.
Your systems don't talk. That's the problem.
The average enterprise runs 130+ SaaS applications. Less than 20% of them share data in real time. The rest operate in isolation — producing insights that never reach the systems where decisions are made, and consuming data that's already out of date by the time it arrives.
Integration isn't a technical problem. It's a business problem. When your CRM doesn't know what your billing system knows, sales reps chase churned customers. When your operations data doesn't reach your finance system in real time, forecasts are guesses.
Maxx Stacks builds the integration layer that makes your systems intelligent — individually and collectively. And when everything connects to MSIL, the intelligence layer can act on the full picture.

API TYPES
The right protocol for every use case.
Not all integrations are the same. Request-response APIs, event-driven webhooks, real-time streaming, and bulk data transfers each have the right use case. We design for the right pattern — not the easiest one.
SYNCHRONOUS
REST API
The workhorse of enterprise integration. RESTful APIs we build are versioned, documented, rate-limited, authenticated, and designed around your data model — not generic CRUD endpoints that expose your internal schema.
BEST FOR: Direct system-to-system data exchange, user-facing features, partner API programs
FLEXIBLE QUERY
GraphQL
When clients need exactly the data they request — nothing more, nothing less. GraphQL APIs we build are schema-first, type-safe, and optimized for the query patterns your applications actually run.
BEST FOR: Frontend data fetching, mobile applications, complex relational data, partner portals
EVENT-DRIVEN
Webhooks
Push events from your systems in real time. Webhook integrations we build include retry logic, event validation, signature verification, and dead letter queues — so events never get lost and systems stay in sync.
BEST FOR: Real-time notifications, cross-system event propagation, MSIL event triggers
HIGH THROUGHPUT
Event Streaming
For high-volume, real-time data flows where polling or webhooks can't keep up. Kafka and message-queue based streaming integrations for operational data pipelines that feed MSIL's continuous intelligence layer.
BEST FOR: Operational data pipelines, IoT data, high-volume transaction streams, MSIL data feeds
PRE-BUILT CONNECTORS
150+ systems, ready to connect.
Pre-built connectors mean production-ready integrations — not configuration wizards. Each connector is built against the system's full API, handles authentication, manages rate limits, and exposes a clean event model to MSIL.
We design and build REST APIs, GraphQL APIs, webhooks, and event streaming integrations. We also build message queue integrations (Kafka, RabbitMQ) for high-throughput event processing. Protocol selection depends on your use case and existing architecture — we recommend the right pattern for each integration.
Pre-built connectors are production-ready integration modules for common enterprise systems — Salesforce, HubSpot, SAP, NetSuite, Workday, Stripe, and 140+ others. They connect your systems to MSIL or to each other without building integration logic from scratch. Each connector handles authentication, rate limiting, error handling, and event normalization.
Yes. We design and build custom APIs — including data modeling, authentication, rate limiting, versioning, and documentation. If you need a new API to expose your data to partners, customers, or internal systems, we build it to production standards with a full API reference document.
MSIL receives data from your systems via API connections. Once connected, MSIL continuously monitors the data streams, detects patterns, and executes actions through the same integration layer. The API layer is the nervous system — MSIL is the intelligence that runs on top of it. Every integration we build is MSIL-ready by default.
