The verdict in three sentences
An RPA robot (UiPath) costs in 2026 between 4,000 and 12,000 EUR/year per robot in licensing plus 8,000-20,000 EUR of build in Dubai, but stays fragile to interface changes (20-30 %/year maintenance). A custom API integration costs 10,000-25,000 EUR, with 10-15 %/year maintenance and far better robustness. RPA is justified when no API exists; as soon as an API is available, custom wins over time.
RPA vs API: the numbers
| Criterion | RPA (UiPath) | Custom API integration |
|---|---|---|
| Annual license | 4,000 - 12,000 EUR/robot | 0 EUR |
| Initial build | 8,000 - 20,000 EUR | 10,000 - 25,000 EUR |
| Annual maintenance | 20 - 30 % of build | 10 - 15 % of build |
| Robustness to changes | Low (UI-dependent) | High (API contract) |
| Setup speed | Fast (2-4 wks) | Medium (4-8 wks) |
| Prerequisite | No API needed | API available |
| High volume | Slows (simulates clicks) | Excellent |
RPA mimics a human clicking through an interface: handy when the target software exposes no API, but any screen change breaks the robot. An API talks to a stable contract, so it resists far better over time.
Total cost over 3 years
| Item | RPA (1 robot) | Custom API |
|---|---|---|
| Build | 14,000 EUR | 17,000 EUR |
| License (3 years) | 24,000 EUR | 0 EUR |
| Maintenance (3 years) | ~12,600 EUR (30 %) | ~5,100 EUR (10 %) |
| 3-year total | ~50,600 EUR | ~22,100 EUR |
Over three years, API integration comes in at less than half the cost when an API exists. RPA keeps its value for legacy software without an API, or for short-lived processes (<12 months).
Decision table: RPA, API or hybrid?
| Situation | Recommended choice |
|---|---|
| API available + durable process | Custom API integration |
| No API + legacy software | RPA |
| Temporary process (<12 months) | RPA |
| High transaction volume | Custom API |
| Mix (some tools with API, some not) | Hybrid RPA + API |

Mini case study
Thomas, IT director at a logistics firm in Dubai (200 staff), must connect his WMS to his ERP. The WMS exposes an API: he picks custom API integration at 17,000 EUR + 1,700 EUR/year maintenance. The RPA route would have cost 14,000 EUR build + 8,000 EUR/year license + 4,200 EUR/year maintenance, i.e. ~50,600 EUR over 3 years against ~22,100 EUR for the API. 3-year saving: 28,500 EUR, with a flow that doesn't break on every WMS screen update.
FAQ
When is RPA the right choice? When the target software exposes no API, for legacy software, or for a temporary process under 12 months where an API investment can't amortize.
Why does RPA cost more to maintain? It simulates clicks in the interface: every screen, field or version change can break the robot, hence 20 to 30 %/year maintenance.
Is API integration always possible? No. It requires both systems to expose a usable API. Otherwise RPA or a hybrid approach is the only option.
How long for an API integration? 2026 order of magnitude: 4 to 8 weeks depending on the number of synced objects and the quality of the available APIs.
Can RPA and API be combined? Yes, hybrid approaches are common: API for modern systems, RPA for legacy software without an API, orchestrated together.
