Onyx Gift Cards is a Grenadian company designed to introduce, market and manage gift cards systems in Grenada for retailers and corporations. We are enthusiastic about the effect and influence we will have on the local market. We intend to expand our systems regionally with a range of product offerings and services.
Gift cards are the preferred way of giving and receiving gifts. They carry a monetary value that can be redeemed for gifts at your favorite store.
Onyx GiftCards are “Open Gift Cards” which means that they can be redeemed at multiple merchant locations. They are standard credit card size, can fit into the average wallet and made of PVC plastic. Onyx GiftCards are Barcoded for security and safety for the consumer and bear a disclaimer at the back.
Onyx Giftcards can be bought with a branded Card backer which is black in colour and is designed to fit the card. There is an area to write a brief message to the recipient as well.
PayPal does not publish one universal test card number. Sandbox test card numbers appear in the PayPal Developer Dashboard after you create a sandbox business account. A sandbox card clears only on sandbox.paypal.com and the sandbox API host. It moves no money, and it fails on live checkout.
A sandbox test card is a card number that PayPal maps to a fixed result inside the test environment. The number carries no bank account and no cardholder. PayPal returns an approval or a decline based on the mapping, the card brand, and the billing address you enter.
Two limits matter:
The list lives in the Developer Dashboard under Testing Tools, then Sandbox Accounts. Open a sandbox account to see the card number, expiry date, and CVV tied to it. PayPal also keeps a card testing page in the REST API reference with sample numbers for several countries.
Numbers differ by region. A US sandbox card can fail on a UK sandbox account because the billing address does not match the account country. Use the number that ships with the sandbox account you are testing against.
Sandbox payments skip real authorization, so any card that passes the Luhn check may still be rejected. PayPal validates the number against its sandbox list first.
INSTRUMENT_DECLINED is the usual failure. It comes from the card mapping, not from a risk model. Other errors trace to a mismatched country, an expired test card, or a checkout session opened against the live host.
A passing sandbox test does not prove production approval. Production runs fraud filters, AVS checks, and cardholder bank rules that the sandbox omits.
Real card numbers in the sandbox break the PayPal user agreement and can trigger account limits. Sandbox numbers have no resale value because no bank issued them.
PCI DSS Requirement 3.2 bars storage of the CVV after authorization, in any environment. Trafficking in payment card credentials falls under 18 U.S.C. 1029 in the United States.
