01
When an API is the first choice
An API works with system logic rather than imitating a user. It normally provides better validation, permissions, scale and error feedback when the vendor offers reliable documentation and versioning.
Confirm that the API supports the exact read and write operations required. The existence of an API does not guarantee access to every function.
02
When RPA is reasonable
User-interface automation can help with a legacy system, a moderate workload or a temporary bridge before replacement. It is more exposed to layout changes, pop-ups, delays and changed messages.
Use controlled accounts, secure credentials, active monitoring and a manual takeover procedure. Treat the robot as an operational component, not a recording that will run forever.
03
Other useful patterns
Managed file exchange, webhooks, event queues or an existing integration module may be a better fit. Frequency, latency, criticality and both systems’ capabilities should drive the decision.
- stable case identifiers;
- idempotency and duplicate protection;
- event order and delay handling;
- safe error logging;
- reconciliation after an outage.
04
Compare lifetime risk
Compare build and three-year operating cost, vendor dependency, security, scale, support and repair time.
The cheapest prototype can become the most expensive operational solution when it lacks monitoring, tests and clear responsibility.
