What RPA is and how it differs from an API integration

RPA (robotic process automation) is software that repeats the actions a person performs on a computer: it opens a system, copies data, fills in forms, downloads files. An API integration, by contrast, connects two systems directly, without going through the screen. Both automate tasks; the difference lies in how they do it and in when each one is the right choice.

How RPA works

An RPA robot works on the application's user interface, just as a user would: it clicks, types and reads what appears on screen. You define a sequence of steps, and it runs them as many times as needed, at any hour.

Common examples in administrative departments:

How an API integration works

An API is a door that a system provides so other systems can exchange data with it in an orderly way. An API integration sends and receives information directly between systems: when a sale is recorded, the other system receives it instantly, with validations and without depending on how the screen looks.

Main differences

When each one makes sense

An API integration makes sense when the systems provide one, the volume is high, information has to travel in real time or the process is critical to operations.

RPA makes sense when the system has no API, it is a legacy system that will not be replaced soon, you need a quick solution for a specific process, or you have to work with third-party portals where there is no other option.

They are combined when a process runs through several systems and only some of them have an API. The integration is done through the API where possible, and RPA covers the remaining step.

RPA with artificial intelligence

Artificial intelligence extends what an automation can do: read documents that have no fixed format, classify emails, interpret inquiries or decide which department a case should be routed to. Combined with RPA and APIs, it makes it possible to automate complete processes, not just isolated tasks.

Frequently asked questions

Short answers to the most common questions on this topic.

Does RPA replace people?

It replaces repetitive tasks. People remain in charge of exceptions, controls and decisions.

What happens if the system the robot uses is updated?

The robot may need to be adjusted. That is why, when an API exists, it is usually the more stable option.

Can you start with RPA and move to an API later?

Yes. It is a common strategy while a system is being modernized.
