Best Practices

Access Control

Only invoices you created or where you are the vendor owner are accessible (unless you have admin or auditor role)
Use the invoice id returned from the invoice creation endpoint to retrieve details
Check the processingStatus.isReady field to ensure the invoice is fully processed before using its data

Invoice States

Common invoice states: DRAFTED, PENDING, APPROVED, PAID, DECLINED
Use processingStatus field to track invoice processing for newly uploaded invoices
Check syncState to verify accounting system synchronization status
