about

What is ONYX GiftCards?

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.

What is a Gift Card?

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.

How it Works?

  • Buy an Onyx Gift Card at these local stores
  • Give your gift card to friends, family, co-workers, etc.
  • The recipient can shop at our select merchants nationwide
  • Your friends, family, co-workers, etc. will present their gift card at checkout to pay for your item(s)
  • They will walk away happy with the best gift ever...the gift of Choice

Why ONYX GiftCards?

  • Save TIME. No need to run around looking for the perfect gift
  • Redeem from a variety of business island-wide. We will continue adding businesses as fast as ONYX grows.
  • ONYX Gift Cards do not expire
  • Cards are valued at convinient amounts to meet every need and occasion

Braintree test card numbers are fixed sandbox values that simulate a card payment without touching a real account. They authorize only when the request goes to Braintree's sandbox with sandbox API credentials. Sent to production, the same numbers fail.

What the sandbox actually tests

The sandbox runs the full payment flow: client token creation, card validation, 3D Secure steps, authorization, and settlement simulation. A test card returns a canned response instead of reaching an issuer. That lets you assert on the transaction result object, exercise decline paths, and check what your interface shows when a card is rejected.

Prerequisites

Steps

  1. Open the control panel and set the environment selector to Sandbox.
  2. Copy the sandbox merchant ID, public key, and private key into your local config.
  3. Generate a client token on the server and return it to the browser.
  4. Render Drop-in or hosted fields using that token.
  5. Enter one of the numbers listed below with any future expiry date and any three or four digit CVV.
  6. Submit the form and log the returned transaction object: status, processor response code, CVV result, and AVS result.
  7. Repeat with a different amount to reach the decline and error branches.

Test card numbers

These values appear in Braintree's testing documentation. Check them against the current docs before you hardcode them into a suite.

Triggering declines without a special card

The sandbox accepts documented transaction amounts that return specific processor responses, so you can test a decline while using a number that normally approves. Look up the current amount to response table in the testing docs, then map each amount to one assertion in your suite.

Common failures

Keep real card data out

Never paste a live card number into a sandbox form or a test fixture. Sandbox numbers belong in fixtures. Live card data belongs with your processor, and logging full numbers in either environment breaks PCI DSS requirements.
