⚡ Reliability
Best When
A Malaysian merchant or SEA business wanting AI agents to automate FPX, e-wallet, and card payment acceptance through iPay88's established Malaysia-native payment gateway with 20+ years of SEA market presence.
Avoid When
FPX BANK PORTAL REDIRECT REQUIRED: FPX payments require customer redirect to their Malaysian bank's online banking portal; automated FPX checkout must redirect customer to FPX gateway; automated server-side FPX bank debit without customer redirect creates payment flow violation. BNM REGULATORY COMPLIANCE: iPay88 operates under Bank Negara Malaysia (BNM) regulations; automated payment must comply with BNM payment system rules; automated payment without merchant BNM compliance creates regulatory risk. MERCHANT AUTHENTICATION USING SHA1 HASH: iPay88 requires SHA1 hash of payment parameters for authentication; automated request must compute correct hash; automated request without hash creates authentication failure. E-WALLET REDIRECT REQUIRED: Touch n Go, Boost, and GrabPay require customer redirect to wallet app; automated wallet checkout must redirect customer; automated server-side wallet charge creates unauthorized charge.
Use Cases
- • Accepting FPX bank transfers from Malaysia online banking checkout agents
- • Processing Touch n Go e-wallet from Malaysia mobile payment agents
- • Handling Visa/Mastercard payments from Malaysia card commerce agents

Not For
- • Pan-SEA at scale (use Xendit or 2C2P for broader multi-country SEA)
- • International payments outside SEA (use Stripe or Adyen for global)
- • Real-time settlement (iPay88 settles T+1 to T+3)

Agent Metadata
Known Gotchas
- ⚠ FORM-POST BASED CHECKOUT: iPay88 uses HTML form POST to iPay88 gateway URL (not JSON REST); automated checkout must redirect customer via form POST; automated JSON REST direct charge creates payment method not supported error
- ⚠ SHA1 HASH PARAMETER CONCATENATION: iPay88 hash requires specific parameter concatenation (MerchantKey+MerchantCode+RefNo+Amount+Currency); automated hash must use exact concatenation order; automated wrong order creates hash mismatch authentication failure
- ⚠ AMOUNT FORMAT WITH NO THOUSAND SEPARATOR: iPay88 amount format is decimal with no thousand separator (e.g., '100.00' not '1,000.00'); automated amount formatting must use decimal without comma; automated comma-formatted amount creates amount parsing error
- ⚠ BACK-END POST URL FOR SERVER CONFIRMATION: iPay88 sends server-to-server payment confirmation to BackendPostURL; automated payment system must implement BackendPostURL endpoint; automated frontend-only checkout without backend post URL creates no server-side payment confirmation
- ⚠ REFNO UNIQUENESS PER TRANSACTION: iPay88 requires unique RefNo per payment request; automated retry must generate new RefNo; automated same RefNo creates reference conflict or duplicate transaction
