Overview

Have an API built for your systems, or connect with suppliers who only offer FTP or CSV. Duxly works on both sides of the supplier chain — building APIs and doing the integration.

When standard tools stop working

Standard apps are useful for predictable flows. They usually fall short when your operation has exceptions, legacy fields, multiple systems, or business rules that cannot be expressed in a settings screen.

  • Orders, stock, invoices, or product data need different rules per channel, warehouse, country, or customer group.
  • The connector works for the happy path, but errors still need manual checks in spreadsheets or admin panels.
  • Your ERP, WMS, marketplace, or supplier feed uses fields that the standard app cannot map cleanly.

What we deliver

  • Sync products, orders, and inventory between your platform and your systems.
  • Reduce manual exports and prevent data drift.
  • Add monitoring and error alerts for stability.

Typical use cases

  • Inventory and order synchronization
  • Reduced manual work and errors
  • Reliable reporting for leadership

Why Duxly

We do not replace standard tools when they are enough. We step in when the real workflow needs architecture, business logic, monitoring, and validation that generic connectors do not provide.

Frequently Asked Questions

When do I need an API instead of a standard integration?
You need a custom API when your supplier only offers FTP or CSV, when you want to build your own API for your customers, or when standard integration tools cannot support the required data structure or business logic.
Can Duxly add an API to an existing system?
Yes. If you have a legacy system (ERP, WMS, PIM) without an API, we build an API layer around it. Your system does not need to change — we expose the data via a modern interface.
How long does it take to develop an API?
A simple REST API goes live in 3-6 weeks. More complex APIs with multiple endpoints, data models, and authentication mechanisms take 6-12 weeks. We always start with a free discovery call.
What is the difference between an API and an FTP connection?
FTP is asynchronous file exchange — you put a file in place and the other party picks it up later. That introduces delays and requires manual checks. An API is real-time: as soon as something changes, it is immediately available.
