7. Go live

Once the Sandbox sync is clean, switch to Production.

Switch to Production

1. Settings → Payhawk → set API Mode to Production.
2. Paste the Production API key (the Sandbox key is kept separately and stays).
3. If you use a group account, confirm the Group ID / Group Key for Production.
4. Run Synchronize data with Payhawk once manually.
5. Confirm new PHWK… fund-account journals appear (Production prefix).
6. Re-register the webhook URL in your Production Payhawk account.

Sandbox vs Production journals

Sandbox creates PSND… journals; Production creates PHWK… journals. They coexist — expect both sets if you tested in Sandbox first.

Go-live checklist

• [ ] Production API key entered, API Mode = Production
• [ ] First manual Production sync completed without errors in the Sync Log
• [ ] Account ID auto-filled
• [ ] PHWK… fund-account journals created
• [ ] Bills/Receipts journals selected (or default purchase journal acceptable)
• [ ] Expense products & tax rates selected and pushed
• [ ] Suppliers reconciled (spot-check a few VAT numbers both sides)
• [ ] Webhooks enabled and URL registered in Production Payhawk
• [ ] Scheduled action "Payhawk Data Sync Runner" is active
• [ ] Error reporting left enabled (so PLANA can help proactively)

After go-live

• The scheduled sync runs every 15 minutes; webhooks handle real-time events.
• Watch the Sync Log for the first day; warnings are usually data-quality issues (e.g. an invalid supplier email) and are safe.
• Old log entries auto-prune per the Delete Logs Older Than setting.
