RPA (Robotic Process Automation) is a robot that automatically operates on software interfaces like humans — pressing buttons, typing keys, reading the screen. Workflow automation connects the system via API — faster, more stable. Zenify recorded a 35% reduction in processing time (approved).
TL;DR
- RPA imitates human actions on the interface.
- Workflow automation nối hệ thống qua API.
- RPA is used when there is no API (old software).
- Workflow automation is faster and more stable.
- Combination: prioritize API, RPA for the rest.
What is RPA?
RPA is robotic software that imitates human operations on computers:
Actions RPA does
Press the button, type
Read data on screen
Copy, paste, input
Transfer data between windows
Xử lý file (Excel, PDF)
What is Workflow automation?
Workflow automation connects systems via API — no "screen viewing":
Features | Description
Kết nối | Hệ thống nói chuyện trực tiếp với nhau
Speed | Instant
Stability | High, few errors
Example | Message → create ticket → update CRM
Compare RPA and workflow automation
Criteria | RPA | Workflow automation
How it works | Interface operations | API Connection
Speed | Slower (human simulation) | Fast, instant
Stability | Easily error-prone when the interface changes | Stable
Need API | No need | Need
Suitable | Old software, no API | Modern system
Maintenance | High (change screen is broken) | Low
When to use RPA?
Old software does not have API.
Internal system does not open connection.
Need urgent automation on tools with available interfaces.
For example, importing data from Excel into old accounting software.
When to use workflow automation?
The system has API (CRM, ticketing, messenger).
Need instant synchronization of data.
Cross-channel process: message → ticket → CRM.
Want stability, little maintenance.
How to choose the right one
Check API: the system has an API → use workflow automation.
No API: just think about RPA.
API priority: fast, stable, cheap to maintain.
Additional RPA: for remaining legacy systems.
Measure and monitor: check error rate by month.
