How to Automate Software With No API

Minicor is a desktop automation platform that lets engineering teams and AI agents automate any legacy software, even when there is no API, no integration, and no documentation. You describe the workflow, Minicor handles everything after that.

The problem: most software was never built to be automated

Thousands of businesses run on desktop software that was built before APIs existed. Systems like CDK, Reynolds & Reynolds, Epic, and DealerSocket are critical to daily operations but they were never designed to talk to anything else.

That leaves teams with two bad options: hire people to do it by hand, or spend months building brittle automation scripts that break every time the UI changes. The problem is that neither is scalable.

What does "no API" actually mean?

An API (Application Programming Interface) is the standard way software exposes its data so other systems can read from it or write to it. When software has no API, there is no official way to get data in or out programmatically.

This is common in:

• Auto dealership software: DMS platforms like CDK Global and Reynolds & Reynolds were built for Windows in the 1990s and still dominate the market

• Healthcare software: EHR systems often have limited or expensive API access, if any

• Government and financial systems: legacy platforms that haven't been updated in decades

• Internal enterprise tools: custom-built Windows apps with no documentation

The absence of an API doesn't mean the software can't be automated, but it does mean that you need a different approach.

The three approaches to automating software with no API

1. Screen scraping (fragile, not recommended)

Screen scraping tools take screenshots of the UI and try to read information from pixel coordinates but they break whenever a window is resized, a font changes, or the software updates. Maintenance cost is high and reliability is low.

2. Traditional RPA (better, but still brittle)

Tools lcan interact with desktop applications directly by clicking buttons, reading fields, and entering data. They work better than screen scraping, but they still rely on the UI staying exactly the same. When it changes, the automation breaks and someone has to fix it by hand.

3. Interface with legacy systems (what Minicor does)

Minicor agentically builds self-healing automations on any no-API system, then hands you an API endpoint to call. You call the API endpoint like you would for any API integration and Minicor handles the rest.

What you can automate with Minicor

• Pulling vehicle inventory from CDK or Reynolds & Reynolds into your own database

• Entering deal data into a DMS without touching the keyboard

• Reading patient records from an EHR and routing them to downstream systems

• Automating data entry into government portals or financial platforms

• Giving AI agents the ability to control desktop software they would otherwise have no access to

In our experience, any workflow that a human can do by clicking through a desktop application can be automated with Minicor, regardless of whether the software has an API.
