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.
A card test payment gateway is a sandbox environment that lets you run the full checkout, authorization, capture, refund, and dispute flow using processor-issued test numbers instead of real ones. It is the standard way developers verify an integration before go-live, and the only legitimate way to see how your gateway behaves when a card is declined, expired, or flagged. This guide covers what a test gateway does, what to look for, and how to stay compliant while you build.
You get a sandbox account with publishable and secret API keys, a set of test card numbers, and documented trigger values that produce specific responses. Everything runs against a mirrored copy of the production API, so endpoints, headers, and error codes match what you will see live. The numbers are issued by the processor, work only in sandbox mode, and cannot move funds. No real cardholder data is required or accepted at any point.
Access is delivered digitally, usually within minutes of checkout, along with setup notes for common frameworks and languages. Nothing ships physically. If the sandbox does not match your integration needs, request a refund within the stated window and it is returned to the original payment method.
Yes. These numbers exist specifically for development and are published by the gateway for that purpose. Entering a real card number that does not belong to you is card fraud, not testing.
No. Sandbox numbers are rejected by live endpoints by design, which is exactly what separates legitimate integration testing from a card-testing attack.
Most teams complete a first successful authorization in under an hour, then cover declines, refunds, and webhooks in a single afternoon.
