Notes

⏱️ 15-Minute Sequential Flow Window

All requests from Step 1 to Step 7 must be executed sequentially within a 15-minute window. The session token received from Step 1 expires in 15 minutes. Ensure fast and synchronized execution.

💰 Wallet Billing & Instant Auto-Refund

For money transfer (Step 7), your wallet is locked and debited atomically.
If the downstream transfer fails (Status 0 or provider decline), your wallet is 100% instantly auto-refunded.

🛡️ Dual-Token Security Architecture

Header Token: Send standard Sanctum Authorization: Bearer <API_TOKEN> in headers.
Body Token: The token parameter in request body is received from previous steps (Steps 2, 4, 5, 7 require the body token).
