Integrations
Connect Custom API to Oman e-invoicing with Dhara
Custom API doesn't handle the full Fawtara process on its own. Dhara does that part. Keep raising invoices in Custom API — your invoice data is checked, mapped to PINT OM, exchanged over Peppol, and tracked from one place.
Custom API does not currently manage the full Oman e-invoicing process directly. Dhara connects to Custom API, checks your invoice data, maps it to PINT OM and manages Peppol exchange through one platform.
