Why GestiumAPI?

An API designed for Algerian businesses

Zero infrastructure to deploy
Your clients access their invoices without servers, without maintenance costs and without training. GestiumAPI handles the entire technical layer for you.
Native integration with GestiumERP
GestiumAPI is directly connected to your GestiumERP or GestiumPRO commercial management software. Every issued invoice is immediately available via the API - without manual synchronization.
Enterprise security by design
Each client only sees their own data. Mandatory HTTPS, time-limited OAuth2 tokens, complete audit logs and data encryption at rest.
Scalable to your volume
Whether you have 50 or 50,000 clients, GestiumAPI scales automatically. Plans are priced by request volume, not per user.
Cirtasoft technical support
Our technical team supports you from initial integration to production. Complete documentation, test sandbox and dedicated support included in every plan.
