Auto-Fill Forms, Rotate Proxies, Log Approvals — No Manual Per-Card Entry
━━━━━━━━━━━━━━━━━━━━━━━━━
Mass-test card numbers against live Stripe checkouts — the extension auto-fills BIN data, fires submissions, and reports which cards fire (live vs declined). Load once, paste your BIN, let it run. Works on any Stripe-powered site.
Below: download, two verified test sites with working BINs, the 7-step setup, optimization tips, and what to watch for.
━━━━━━━━━━━━━━━━━━━━━━━━━

├─ 
Auto-fills forms (no manual entry per card)
├─ 
Proxy support (rotate IPs)

Test Sites (Verified Working)
| Site | URL | Working BIN | Status |
|---|---|---|---|
| OneOver | https://oneover.com | 3793630397 |
Live |
| Recraft | https://recraft.ai | 3743551264 |
Live |
Both sites run real Stripe checkouts. Use these to verify your setup works before testing elsewhere.

Do’s
- Use residential proxies — datacenter IPs trigger fraud alerts faster
- Test in small batches (100–500 cards/hour) — large bursts get rate-limited
- Rotate user-agents between submissions (browser fingerprint variation)
- Monitor for 3D Secure challenges — approved cards that then fail auth
- Log results to a file — track approval rate, retry declines later
- Use verified test sites first — confirms the extension + your BIN logic work
Don’ts
- Don’t test all cards at once — you’ll get IP-banned in minutes
- Don’t use datacenter proxies only — Stripe’s fraud filter flags them hard
- Don’t ignore rate limits — a 429 (too many requests) ends your session
- Don’t skip 3D Secure handling — some approved cards block at auth step
- Don’t reuse the same card across different merchants rapidly — triggers velocity checks
- Don’t post raw BINs publicly — they burn fast once shared

Common Issues & Fixes
🔴 'Extension blocked' — browser security warning
Stripe has gotten aggressive at flagging auto-submission. If the extension stops firing:
Switch browsers — try Edge or Brave instead of Chrome (Chromium still flags it, but Edge sometimes slides through longer)
Rotate residential proxies — datacenter IPs trigger this instantly
Clear cookies/cache — Stripe’s cookies flag repeat testers
🔴 'Form can't find card field' — script can't locate input
The site’s Stripe form may have changed or use a non-standard element:
Inspect the page (F12 → Elements) → find the card field → check its id or class
Update the extension config to match the new field name (check extension docs in the ZIP)
Test on a known working site first (OneOver) — if it works there but not elsewhere, the target site changed its form
🔴 'Rate limit hit' (HTTP 429) — too many submissions too fast
Stripe’s gateway is rate-limiting your IP:
Wait 5–10 minutes — then resume at half the speed (test slower)
Switch proxies — a fresh residential IP resets the counter
Reduce batch size — test 50 cards/batch instead of 500
🔴 'Cards declined but extension says approved' — mismatch
3D Secure (2FA) is approving at the gateway but failing at the auth step:
Don’t count these as live — they’re dead-end for checkout flow
Log them separately — useful for testing but not for actual transactions
Check the response headers — look for requires_action: true (signals 3DS)
