What can you build with the Gesvision API?
🧾 Invoices & Credit Notes
Full lifecycle management of invoices — create, issue, rectify and cancel. Multi-currency, multi-tax, insurance billing, electronic invoicing (SII, Verifactu, CFDI) and fiscal printer support.
📦 Orders
Manage sales orders, subscriptions, and manufacturing workflows. Track order status, shipping, and link orders to invoices and delivery notes.
💳 Payments
Register payments with cash, card (POS integration), bank transfer, or custom methods. Track installments, partial payments, and automatic change calculation.
👤 Customers
Query and update customer data, contact info, addresses, and subscription status. Patch semantics — update only the fields you need.
🔒 Optimistic Concurrency
Built-in version control using the If-Match header. Prevent lost updates when multiple systems modify the same resource simultaneously.
🔄 Incremental Sync
Use modifiedAfter / modifiedBefore filters to efficiently synchronize data. Perfect for e-commerce, accounting, and CRM integrations.
