Developer API

Connect your own software directly to PI Fiscal. Your system sends an invoice, we sign it and submit it to ZIMRA, and you receive the fiscal number, QR code and verification code back — typically in about a second.

How it works

Requests are authenticated with per-customer API credentials issued from your portal. Submissions are idempotent, so a network retry can never create a duplicate ZIMRA submission. Rendered 48mm and A4 documents are available for every fiscalised invoice. Full endpoint reference, payload schemas and SDK examples are published to customers inside the portal.

Setup

1. Sign in to your portal and create API credentials.
2. Follow the technical documentation provided there to send your invoices.
3. Store the returned fiscal number and render the returned document.
