API design & build
REST and GraphQL APIs designed to be clear, versionable and testable.
APIs & Integrations
APIs and integrations that make your tools talk.
Connect CRMs, ERPs, payment and logistics systems into one reliable layer, designed to be readable, testable and safe to change.
Why it matters
The value is rarely in one system. It's in getting them to agree with each other.
We design and build the APIs and integrations that sit between your systems, syncing data, automating hand-offs and removing the copy-paste work. Built with clear contracts, retries and monitoring so a third-party outage doesn't take you down with it.
- Clean, documented API contracts
- Resilient syncing with retries and alerting
- No more manual data re-entry between tools
What's included
Everything your API integration engagement covers.
Third-party integrations
Salesforce, HubSpot, SAP, Stripe, shipping carriers and more.
Data sync
Two-way syncing that keeps records consistent across systems.
Automation
Event-driven workflows that remove slow manual hand-offs.
Auth & rate limiting
Secure keys, OAuth and sensible limits for your partners.
Monitoring
Logging and alerts so integration failures surface fast, not silently.
Process
How your API integration project runs.
- 01
Discovery
We map your goals, users and constraints, then agree a scope and a fixed estimate.
- 02
Design
Wireframes, prototypes and a design system, validated with real users.
- 03
Build
Two-week sprints with a working demo at the end of every one.
- 04
Quality assurance
Automated and manual testing across devices before anything reaches users.
- 05
Launch
A rehearsed release with monitoring in place, not a fingers-crossed deploy.
- 06
Support
Ongoing iteration, maintenance and a real person to call when you need one.
Why Infyze
Why teams choose us for this.
A senior team, no hand-offs
The people who scope your project are the ones who build it, no junior bait-and-switch.
Fixed scope, honest estimates
Work is broken into two-week increments you can see and steer, priced before we build.
A working demo every Friday
You never wait months to see progress. Each week ends with something you can click.
You own everything
The repository, the pipeline and the documentation are yours. No lock-in, no dependency.
Results we can measure
We tie the work to numbers that matter to you and report against them honestly.
We stay after launch
Support and iteration are part of the relationship, not an upsell once real users arrive.
The stack
Technologies we use for this.
- Node.js
- GraphQL
- REST
- Kafka
- Redis
- OpenAPI
We pick tools to fit your product and team, not by fashion, and we document why, so the choice still makes sense a year from now.
FAQ
Common questions about API integration.
How much does an integration project cost?
It depends on how many systems you are connecting and how complex they are, but you get a fixed price in writing after a short discovery call. For a rough ballpark first, try our free cost calculator.
What kinds of systems can you connect?
CRMs, ERPs, payment gateways, logistics carriers and analytics tools, among others. We design clear, documented APIs and integrations so your systems finally agree with each other instead of needing manual copy-paste.
What happens if a third-party service goes down?
We build in retries, clear error handling and monitoring, so a partner outage surfaces as an alert rather than silently corrupting your data or taking you down with it.
Can you build a public API for our partners?
Yes. We design REST or GraphQL APIs with sensible authentication, rate limiting and documentation, so your partners can integrate safely and easily.
Do you document the integrations?
Always. You get clear API contracts and documentation, so the next developer, ours or yours, can understand and extend the work.
