FazerCards Glossary

Short, factual definitions of industry terms: wholesale gift cards, REST API, webhooks, direct mobile game top-ups, stablecoin settlement, tier discounts, and onboarding.

Gift card API

A REST API that lets a reseller programmatically order digital gift cards (Amazon, Steam, iTunes, etc.) at wholesale prices and receive the code back within seconds.

Wholesale gift cards

Gift cards sold to B2B buyers (resellers) at below face value, intended to be resold to end consumers at the consumer price.

Reseller margin

The gross spread between the wholesale price a reseller pays and the retail price they charge the end customer.

Tier discount

A discount tied to a paid plan tier rather than to individual order volume — the higher the tier, the better the per-order economics.

Bronze / Silver / Gold plans

FazerCards' three subscription tiers. Higher tiers raise wholesale rebates and unlock heavier volume.

Webhook

An HTTP POST request the platform sends to your URL when something happens (order completed, failed, refunded) so you don't need to poll.

Idempotency key

A client-generated unique value (header `Idempotency-Key`) that tells the server to treat repeat POSTs as the same request — prevents duplicate orders on network retries.

REST API

An HTTP API following REST conventions (resources at stable URLs, JSON bodies, standard verbs) — the contract type FazerCards exposes at /api/v2.

OpenAPI

A machine-readable description (YAML/JSON) of a REST API's endpoints, request bodies and responses. FazerCards publishes one at /public/docs.

API key

A long random string that authenticates server-to-server calls. Treated as a password — never embed in client code.

X-Api-Key header

The HTTP header FazerCards uses to receive the API key on every request. Example: `X-Api-Key: live_xxx...`

USDT TRC20

Tether (USDT) on the Tron network. The cheapest and most common stablecoin rail for crypto B2B settlement.

USDT BEP20

Tether (USDT) on BNB Smart Chain. Low fees, fast confirmation, EVM-compatible addresses (0x...).

USDT TON

Tether (USDT) on The Open Network — the chain native to Telegram, with wallets built directly into the messenger.

USDT Aptos

Tether (USDT) on the Aptos chain — high throughput, very low fees, growing reseller adoption.

Binance Pay

Binance's free, peer-to-peer crypto payment rail. Lets you settle in stablecoins straight from a Binance account, no on-chain transfer needed.

Stablecoin

A cryptocurrency pegged 1:1 to a fiat currency (typically the US dollar). USDT and USDC are the main reseller-grade stablecoins.

Steam Wallet

The USD-denominated balance held inside a Steam account. Resellers add credit by ordering Steam wallet top-ups via the FazerCards API.

Steam gift card

A code that adds a fixed face value (e.g. $10, $20, $50) to a Steam Wallet when redeemed.

Robux

The virtual currency in Roblox. Bought through Roblox gift cards or direct top-up (e.g. game-pass), then spent on avatar items, game-passes, and in-experience purchases.

Roblox gift card

A code redeemable at roblox.com/redeem for a fixed Robux amount or premium credit.

PUBG Mobile UC

Unknown Cash — the in-game currency for PUBG Mobile. Delivered to a player by their PUBG ID.

Free Fire Diamonds

Garena Free Fire's in-game currency, delivered directly to a player by Free Fire ID.

Mobile Legends Diamonds

Diamonds, the in-game currency in Mobile Legends: Bang Bang. Delivered directly to a player by ID + server.

Genesis Crystals

Genshin Impact's premium currency, converted to Primogems and used for character/weapon banners.

Valorant Points (VP)

The in-game currency in Riot's Valorant, used for weapon skins, Battle Pass, and bundles.

Riot Access code

A single prepaid code that funds either Valorant Points (VP) or League of Legends RP via a Riot account.

Mobile game top-up

The category of in-game currency top-ups for mobile games — PUBG UC, Free Fire Diamonds, Mobile Legends Diamonds, Genshin Genesis Crystals, etc.

Direct ID top-up

A delivery method where the reseller passes the player's account ID to the supplier and the in-game currency is added directly — no code is generated.

White-label reseller

A reseller who runs their own brand on top of a wholesale supplier. The supplier (FazerCards) is invisible to the end customer.

KYC-free onboarding

Account creation that doesn't require identity documents — the reseller can register, fund balance, and order on the same day.

Telegram Premium

Telegram's paid subscription tier — larger file uploads, stickers, faster downloads. Sold by FazerCards in 3, 6, and 12-month gift activations.

Telegram Stars

Telegram's in-app currency used to pay for digital goods inside Telegram apps and mini-apps.

A cap on how many API calls one client can make in a time window. FazerCards uses per-category limits on the public API (catalog read 30/min, order create 60/min, order status 120/min, account 30/min, payments 15/min) so polling never blocks order creation.

Instant delivery

Order is fulfilled and the code (or top-up) is available to the customer within seconds — no human in the loop.

UC pack

A specific UC (Unknown Cash) denomination sold as a unit — e.g. 60 UC, 325 UC, 660 UC — for PUBG Mobile.

Diamond top-up

Direct-to-account credit of premium currency in mobile games that call their currency 'diamonds' — primarily Free Fire and Mobile Legends.

Roblox game-pass top-up

A Robux delivery method using a private Roblox game with a pass — the supplier buys the pass under the reseller's account, transferring Robux net of Roblox's developer cut.

V-Bucks

The in-game currency in Fortnite, used for skins, the Battle Pass, and V-Bucks card redemptions.

VP / RP conversion via Riot Access

Riot Access codes credit a single balance the player can spend as Valorant Points (VP) or League of Legends Riot Points (RP).

Steam region lock

Steam Wallet codes are region-specific — a US card only redeems on a US-region Steam account. The price you see on Steam Turkey is not transferable to a US account.

PSN region lock

PlayStation Network gift cards are region-locked the same way Steam codes are — a US PSN card only credits a US PSN account.

Google Play country mismatch

Google Play gift cards only redeem on a Google account that's set to the same country as the card. Changing a Google account country is limited to once per year.

Stablecoin settlement

Paying for wholesale goods or services in a USD-pegged stablecoin (USDT, USDC) so price stays stable and settlement is on-chain in minutes.

On-chain confirmation

Inclusion of a crypto transaction in a block + N subsequent blocks, after which the supplier considers the payment final and credits the reseller balance.

Chargeback

A reversal of a card payment initiated by the cardholder or their bank, weeks or months after the original transaction.

Stablecoin vs card payment

Trade-off for resellers: stablecoins (USDT) are cheaper, faster, and chargeback-free, while cards are more familiar but cost 2–3% in processing fees and expose the merchant to chargebacks.

Webhook signature

An HMAC tag in the webhook request header so the receiver can verify the call really came from FazerCards and the body wasn't tampered with in transit.

HMAC

Hash-based Message Authentication Code — a cryptographic construction (key + hash) that proves a message originated from someone who knows the key and wasn't modified in transit.

Retry-After header

An HTTP response header (RFC 7231) telling the client how long to wait before retrying a request — used by FazerCards on HTTP 429 rate-limit responses (per-category ceilings: catalog 30/min, order-create 60/min, order-status 120/min, account 30/min, payments 15/min).
