- SSL on checkout and account pages

- Full list of production EDD extensions

Low-volume launch tip: even if you expect few sales at first, run the full decline and browser-close tests—edge cases arrive with your first real customer, not your tenth.
Finance handoff: export one sandbox and one live transaction report from Quantum alongside EDD payment export so bookkeeping trusts the integration before month-end close.
3. Setup checklist
- [ ] Test mode prevents live charges during QA
- [ ] Return / callback URLs match staging hostname
- [ ] Cache plugins exclude checkout and gateway endpoints
- [ ] Receipt emails show correct total and reference
- [ ] Statement descriptor approved by finance
Fulfillment patterns: EDD payment setup for digital products.
4. Sandbox test matrix
| Test | Pass criteria |
|---|---|
| Successful payment | EDD complete; download available |
| Declined card | No access granted |
| Browser closed before receipt | Async completion unlocks file |
| Refund | References consistent in EDD + Quantum |
| Recurring (if applicable) | EDD Recurring synced |
Methodology: how to test your payment gateway like a pro.
5. Go-live
- Live credentials; disable test mode.
- Low-value live purchase; refund it.
- Monitor pending payments 48–72 hours.
- Maintain plugin license renewal.
Recurring digital products: EDD subscriptions and payment gateways.
6. Descriptor and branding checklist
Quantum statement descriptors should match the brand on your EDD product pages. Digital buyers who do not recognize a charge file chargebacks at higher rates than physical goods sellers. Align copy with chargebacks vs refunds playbooks.
7. Renewals and regression testing
After each EDD minor or major update, rerun one sandbox purchase before peak traffic—especially if you defer plugin updates. Pair with safe payment gateway plugin updates mindset (EDD screens differ; discipline is the same).
8. When to escalate beyond the plugin
custom payment gateway integration for headless delivery, split payouts, or processor metadata EDD does not pass by default.
