API development.

All your business tools connected into one seamless system. No more manually transferring data between platforms every single day.

Before / After

Your tools don't talk to each other. They should.

Before

“Everything is connected. Nothing is integrated.”

  • You have twelve tools and none of them share data automatically.
  • Someone exports a file from one system and uploads it to another. Every day.
  • Your AI model is powerful but it can't access the data it needs to be useful.
  • A new platform launch gets delayed because the integration work takes months.
  • You're paying for software that can't communicate with the rest of your stack.
After

“Everything connected. Everything automatic.”

  • We build the APIs that sit between your systems and make them work as one.
  • Data flows in real time. No exports. No manual transfers. No delays.
  • Your AI models get the data they need, when they need it, without anyone managing the pipeline.
  • New integrations take days, not months because the architecture is built to extend.
  • Your entire stack moves together, at the speed your business demands.
What We Build

Three types of API. One standard of quality.

Every API we build is documented, versioned, secured, and designed to scale. No shortcuts. No tech debt handed back to your engineering team.

01

Integration APIs

System-to-System Connections

We build the connective tissue between your existing tools: CRMs, ERPs, databases, payment systems, third-party platforms. Clean, reliable integrations that eliminate manual data movement entirely.

02

AI APIs

Intelligence Pipelines

We build the APIs that give your AI models access to your live business data, feeding them the right information at the right time, routing their outputs to the right destinations, and keeping everything in sync.

03

Product APIs

Customer-Facing Interfaces

We build production-grade APIs that power your product, enabling third-party developers to build on your platform, exposing your capabilities as a service, and turning your internal systems into a scalable product surface.

Use Cases

The proof is in the build.

Here's what custom API development looks like when it's done properly, across every part of your business.

  • 01

    CRM-to-ERP Sync

    A real-time API that keeps your CRM and ERP in perfect alignment. Customer records, order data, and financial information flows between systems the moment anything changes.

  • 02

    Payment and Billing Integration

    We build the API layer between your platform and your payment infrastructure, handling transactions, webhooks, refunds, and reconciliation without any manual intervention.

  • 03

    Multi-Platform Data Unification

    A single API that pulls from every tool in your stack and serves unified data to wherever it's needed, in real time. No more disconnected reports or stale dashboards.

Our Approach

We assess first and build only what works.

Every engagement starts with a full audit of your tech stack before we design a single endpoint.

01

Discovery

We audit your current tech stack and map every integration gap, data flow requirement, and system dependency.

Complete Stack Audit
02

Blueprint

Every API gets architected end to end with authentication, versioning, and error handling defined before we write code.

API Architecture
03

Build

We build directly into your environment with rigorous testing at every stage, including load, security, and integration tests.

Built to Last
04

Launch & Train

We deploy, document fully, and hand over so your team can maintain and extend everything we've built.

The Syntora Advantage

Not all API development partners are built the same.

Architecture First

Other agencies

Build first, refactor later

Syntora

We design the full API architecture before writing a single line

Ownership

Other agencies

Proprietary tools or vendor dependency

Syntora

Full codebase, documentation, and infrastructure handed over. No lock-in

Security Standard

Other agencies

Security often added as an afterthought

Syntora

Auth, rate limiting, encryption, and audit logging built in from day one

Your Stack

Other agencies

May require additional tooling or migrations

Syntora

Integrates with what you already use, no new platform purchases

Post-Launch

Other agencies

Limited documentation and no guaranteed support

Syntora

Full documentation, handover session, and optional ongoing support

Every great build starts with a conversation.

You don't have to figure this out alone. That's exactly what we're here for.

Frequently asked

Everything you're thinking, answered.

How long does a custom API build typically take?

Most API builds are completed within a few weeks depending on complexity, the number of systems involved, and the state of your existing infrastructure. We move fast because we've built this kind of infrastructure before but we never rush at the cost of quality.

Can you integrate with any third-party platform or tool we use?

How do you secure the APIs you build?

Do we own the code and infrastructure at the end?

What happens if something breaks or needs to change after launch?

Why not just use Zapier, Make, or another integration platform?
