CARDING IN-APP PURCHASES (IAP)

[Professor]

The Complete Carder's Guide​

Bro, have you ever banged your head against a website where everything is configured perfectly, but the order just won't go through? Or maybe your cards have already burned every payment processor, and you're blacklisted by Stripe, Forter, and Riskified? That's frustrating, I agree.

But there's a secret backdoor that most people ignore: in-app purchases (IAP). These mobile transactions run on a completely different payment rail, opening up a world of opportunities for those who know how to think outside the box.

This guide isn't just a translation. It's a complete manual with step-by-step instructions, method comparisons, system setup, strategies, mistakes and how to fix them.

PART 1: WHY IAP IS A GOLDMINE​

1.1. The Security Imbalance​

The core truth is that companies invest massive resources into protecting web payments, but IAP security is completely outsourced to Apple and Google.

Example: ChatGPT

Channel	Payment Gateway	Anti-Fraud	Difficulty
Web	Stripe	Stripe Radar (aggressive)	High
IAP (iOS)	Apple App Store	Apple (device-based)	Low
IAP (Android)	Google Play	Google (account-based)	Medium

Example: Roblox

Channel	Payment Gateway	Requirements	Difficulty
Web	XSolla / Stripe	Registration, card verification, fees	High
IAP	App Store / Play Store	Just Apple ID / Google account	Low

Conclusion: While everyone is banging their heads against hardened web gateways, you slip through the backdoor of mobile apps.

1.2. Why This Works​

1. Different payment rails — web and IAP are processed by different systems
2. Different anti-fraud systems — Stripe Radar doesn't see IAP transactions
3. Different limits — a card blocked in Stripe may work in Apple
4. Different checks — Apple/Google check device/account, not card

1.3. What You Can Buy Through IAP​

Category	Examples	Liquidity
Game currency	Robux, V-Bucks, Genshin Impact	Very high
Subscriptions	HBO, Hulu, Disney+, Spotify	High
Apps	ChatGPT Plus, Canva Pro, Notion	Medium
In-game items	Skins, weapons, characters	High
Crypto	Purchases through exchange apps	Medium

PART 2: IPHONE VS ANDROID — DETAILED COMPARISON​

2.1. Apple App Store: Device-Level Security​

How it works:

• Apple monitors patterns on a specific device, not on the account
• Too many purchases on one phone → flag → block
• Device reset (format) helps clear some flags

Apple Pros:

Advantage	Details
Low barrier to entry	New iPhone + format + new Apple ID
No mini-payments	No card verification needed
No account age requirements	Fresh Apple ID works immediately
Simplicity	Card alive → purchase goes through
No 3D Secure	Apple doesn't require OTP

Apple Cons:

Disadvantage	Solution
Device block at high volumes	Swap devices (used iPhones)
Limit per device	No more than $5,000-10,000/day
Apple can block purchases	Reset or new device
Expensive to scale	Used iPhones cost $100-300

2.2. Google Play Store: Account-Level Security​

How it works:

• Google doesn't rely on device ID (easily spoofed)
• All security is in the Google account
• Two types of checks: 3D Secure or mini-payments

Google Pros:

Advantage	Details
Easy to change device ID	One click — new ID
Trusted accounts	Higher limits after verification
Flexibility	Can work from one device
Cheaper to scale	No need for new devices

Google Cons:

Disadvantage	Solution
Mini-payments for verification	Need cards with transaction access
3D Secure	Need Non-3DS BINs
Trust must be earned	Account warming required
Limits on trusted accounts	Don't exceed reasonable volumes

2.3. Comparison Table​

Criterion	Apple App Store	Google Play Store
Security level	Device	Account
Barrier to entry	Very low	Medium
Card verification	Not required	Mini-payments or 3DS
Account age	Not important	Important for trust
Device ID	Hard to spoof	Easy to spoof
Limits	Per device	Per account
Scaling	Through devices	Through accounts
Startup cost	$100-300 (iPhone)	$50-150 (Android)
My choice	For beginners	For pros with logs

Verdict: Apple — for those who want to start fast. Google — for those with logs who are ready to warm up accounts.

PART 3: STEP-BY-STEP GUIDE FOR APPLE​

3.1. Device Preparation​

Step 1: Buy a used iPhone

• Model: iPhone X or newer
• Price: $100-300
• Where: eBay, Craigslist, local listings
• Important: Check that the device is not iCloud Locked

Step 2: Full Reset

Settings → General → Reset → Erase All Content and Settings

• This deletes all data and resets the device fingerprint
• Important: Don't restore from backup

Step 3: Set Up as New

• Choose language and region (matching the card)
• Connect to Wi-Fi (preferably through proxy)
• Don't use VPN — Apple sees this

3.2. Creating Apple ID​

Step 1: Create a new Apple ID

• Email: use cardholder's email (if available) or a new one
• Password: complex, unique
• Date of birth: matches cardholder

Step 2: Set up payment

• Add card to Apple Pay
• Verify region matches card billing

Step 3: Test purchase

• Buy something for $1-5 (e.g., an app)
• If it goes through — ready to work
• If not — check card, region, device

3.3. Making a Purchase​

Step 1: Choose target

• Open app (Roblox, Fortnite, etc.)
• Choose product/currency

Step 2: Pay via IAP

• Tap "Buy"
• Confirm via Face ID / Touch ID
• Important: Don't make more than 3-5 purchases in a row

Step 3: Use or sell

• If game currency — sell via Telegram/eBay
• If subscription — use or sell account

3.4. Scaling (Apple)​

For high volumes:

1. Buy multiple used iPhones
2. Set up each as a separate device
3. Use different Apple IDs
4. Swap devices every 2-3 weeks

Limits:

• $5,000-10,000 per day per device
• No more than 3-5 purchases in a row

• Password: complex, unique
• Date of birth: matches cardholder

Step 2: Add card to Google Pay

• Open Google Pay
• Add card
• Google will charge a mini-payment ($0.01-0.50)

Step 3: Card verification

• Log into online banking (log)
• Find the Google transaction
• Confirm the amount in Google Pay
• Important: Without log access, verification is impossible

Step 4: Account warming

Step 3: Use or sell

4.4. Scaling (Google)​

For high volumes:

1. Create multiple Google accounts
2. Warm up each (2-3 small purchases)
3. Verify cards via logs
4. Swap accounts at first sign of flag

Limits:

• $2,000-5,000 per day per trusted account
• No more than 5-10 purchases in a row
• Swap account at first sign of flag

PART 5: SUBSCRIPTIONS AND CHARGEBACKS​

5.1. Why Subscriptions Are Gold​

Most streaming platforms are too lazy to properly implement Apple and Google's chargeback protocols.

How it should work:

• Apple/Google provide APIs for merchant notifications
• On subscription refund, the company should automatically revoke access

How it actually works:

Platform	Integration	Result
HBO	Poor	Access remains
Hulu	Very poor	Access remains
Disney+	Poor	Access remains
Netflix	Better	Sometimes revoked
Spotify	Medium	Depends on case

5.2. Workflow​

1. Buy an annual subscription via IAP ($100-200)
2. A week later, file a chargeback
3. Access remains active for the whole year
4. Sell the account for 50-70% of value ($50-140)

Profit: $50-140 per subscription

5.3. Best Platforms for Subscriptions​

Platform	Price/year	After chargeback	Liquidity
HBO Max	$150	Access remains	High
Hulu	$120	Access remains	High
Disney+	$140	Access remains	High
Spotify	$120	Depends	Medium
ChatGPT Plus	$240	Access remains	Very high

Barrier to entry	High	Very low	Medium
Scaling	Proxies/accounts	Devices	Accounts
Block risk	High	Medium	Medium
Card revival	No	Yes	Yes
Startup cost	$500+	$100-300	$50-150

PART 10: KEY TAKEAWAYS​

Bro, in-app purchases are your secret weapon when traditional carding hits a wall.

Key takeaways:

1. Security imbalance — companies protect web, but not IAP
2. Apple is simpler — low barrier, no verification, works immediately
3. Google is more powerful — trusted accounts give higher limits
4. Subscriptions are gold — chargeback doesn't always revoke access
5. Moderation — don't be greedy, swap devices, watch OPSEC

Strategy:

• Start with Apple for a quick start
• Move to Google when you get logs
• Use subscriptions for long-term income
• Swap devices every 2-3 weeks

Remember: The game isn't about brute force — it's about finding and exploiting security imbalances. Smart money isn't made in one strike — it's built through consistent exploitation of these overlooked vulnerabilities.

Good luck, bro. If anything — ask.
