Check these limits before you build

Customer and supplier master records, chart of accounts, journals, financial dimensions and invoice payments are not supported in Netvisor’s unified endpoints. Need something beyond this coverage? The Proxy API can reach native endpoints, subject to Netvisor’s API and permissions. Discuss your requirements →

Useful data. Real product workflows.

Invoice visibility

Bring sales and supplier invoices into dashboards and finance workflows without building a separate Netvisor data model.

Financial analysis

Use balance sheets, income statements and trial balances as inputs for reporting, forecasting and credit assessment.

Document workflows

Retrieve invoice attachments and upload supporting documents to supplier invoices.

Your first Netvisor request

With an API key and an authorised consent, retrieve sales invoices through the Accounting API.

curl 'https://apione.zwapgrid.com/accounting/api/v1/consents/{consentId}/salesinvoices?Count=100&CurrentPage=1' \
  -H 'x-api-key: YOUR_API_KEY' \
  -H 'x-correlation-id: YOUR_UNIQUE_GUID'

Replace the placeholders. Use a unique correlation ID per request. Page through results with Count (1–100) and CurrentPage (starting at 1).

Plan your invoice sync

Netvisor supports sales-invoice status filters for Paid, Unpaid, Overdue, Cancelled and Unsent. Unbooked and Draft filters are not supported. Schedule reads to suit your product’s freshness needs.
