Custom API development & Bespoke API integration services.
We design, build, and connect APIs that let your systems talk to each other reliably. From REST and GraphQL endpoints to third-party integrations and webhook orchestration, every solution is scoped to your data, your workflows, and your long-term ownership.
United Software Technologies provides custom API development and Bespoke API integration services for small businesses in Ohio and across the United States. We build secure, documented endpoints that connect your internal tools, third-party platforms, customer-facing apps, and data sources — so information moves where it needs to without manual copy-paste or fragile spreadsheets.
APIs built for how your data actually moves.
Our developers deliver custom API solutions for operational efficiency, data synchronization, and platform extensibility. Whether you need a lightweight endpoint that feeds a dashboard or a full integration layer connecting multiple vendors, we design around your business logic instead of forcing your team into rigid off-the-shelf connectors. We're based in New Philadelphia, Ohio and work with clients across Ohio and the US.

A proven process from kickoff to deployment.
Our API development process keeps your project aligned on data contracts, security, and release readiness.
Discovery & data mapping
We map your systems, data sources, and workflows, then define endpoints, contracts, and authentication requirements.
API design & build
Our team builds endpoints and integration logic in structured sprints with progress updates and contract reviews.
Testing & validation
We run integration tests, error handling checks, and load validation to confirm reliability before production.
Deployment & docs
After final review, we deploy your API, deliver documentation, and plan future endpoints or integrations.
Delivery standards built into every API project.
Full code ownership
You retain full rights to the API code and integration logic with transparent handoff documentation.
Clear API documentation
Every endpoint ships with request/response examples, authentication details, and usage notes for your team.
Secure by default
Token-based authentication, rate limiting, and input validation are built in — not bolted on later.
Flexible architecture
Your API is designed to evolve, so new endpoints and integrations remain practical as your business grows.
Error handling & logging
Structured error responses and logging help your team diagnose issues quickly without vendor lock-in.
Post-launch support
After go-live, we can continue maintenance, monitoring, and new endpoint development as needed.
API solutions for core business functions.
CRM & ERP integration
Connect customer records, orders, and inventory between your CRM, ERP, and front-end platforms in real time.
Payment & billing APIs
Sync transactions, subscriptions, and invoices across payment providers and your internal accounting tools.
eCommerce platform APIs
Bridge your storefront with fulfillment, inventory, and reporting systems so orders flow without manual entry.
Internal tool endpoints
Power dashboards, portals, and admin tools with dedicated APIs that expose only the data each role needs.
Third-party data sync
Keep data consistent across SaaS apps, databases, and spreadsheets with scheduled or event-driven sync jobs.
Legacy system middleware
Wrap aging systems in a modern API layer so newer tools can read and write data without replacing everything at once.
Common questions before starting a custom API project.
What types of APIs do you build?
We build REST APIs, GraphQL APIs, webhook listeners, and integration middleware. We also connect existing third-party APIs — CRMs, ERPs, payment providers, shipping platforms, and communication tools — into your internal systems.
Do we own the API and source code?
Yes. You own the delivered API code, integration logic, and documentation. We provide handoff materials so your organization has long-term control of the system.
How long does an API project usually take?
Most API builds launch in 3 to 8 weeks. The exact timeline depends on the number of endpoints, integrations, data complexity, and stakeholder review cadence.
How do you price API development projects?
We provide project-specific pricing after discovery and scope definition. You receive a clear quote with deliverables, endpoints, and a timeline — no surprise hourly billing.
Can you integrate with our current software stack?
Yes. We frequently integrate with CRMs, ERPs, payment providers, shipping tools, marketing platforms, and existing internal systems. If the vendor offers an API or data export, we can usually connect to it.
Do you provide documentation with the API?
Yes. Every API ships with endpoint documentation, request and response examples, authentication instructions, and usage notes so your developers or future partners can work with it confidently.
Do you support the API after launch?
Yes. We provide post-launch support and can continue as your development partner for monitoring, new endpoints, and additional integrations as your needs grow.
