Start
Sandbox
Test host, official PANs, and a test panel on each operation. No real naira moves.
Point every checkout call at https://payment-api-service.dev.payinvert.com with TEST keys. Open Credentials in the header, then send from any operation page.
CORS
Some browsers block the host from this docs origin. If Send request says blocked, copy the cURL tab, or import the Postman collection.
Test cards
Sandbox Mastercard and Visa PANs. Copy one into Card payment.
Verve
Verve cards are not supported on the gateway yet. Charge Mastercard or Visa only.
| Scheme | PAN | Expiry | CVV | PIN |
|---|---|---|---|---|
| Mastercard | 5200000000001096 | 12/50 | 100 | - |
| Visa | 4456530000001096 | 12/50 | 100 | - |
Expiry 12/50 approves. 05/39 is a declined payment (issuer declined). Never use these PANs on the live host.
Prefer a local client: download the Postman collection and import it. That path does not hit browser CORS.
A first charge
- Create order: copy the returned reference.
- Card payment or bank transfer with that reference.
- Order status, then Verify with the secret key.
