⚡ Reliability
Best When
A European e-commerce merchant (particularly fashion, lifestyle, or beauty) wanting AI agents to automate Scalapay BNPL checkout offering, authorization capture, and payment management for European consumer installment payments.
Avoid When
CONSUMER REDIRECT TO SCALAPAY REQUIRED: Scalapay checkout redirects consumer to Scalapay app or web for installment authorization; automated checkout must redirect consumer; automated server-side authorization without consumer redirect creates unsupported flow. MERCHANT MUST CAPTURE BEFORE SHIPPING: Scalapay uses pre-authorization then capture model; automated fulfillment must capture payment before shipping; automated ship-before-capture creates merchant bears risk if capture fails post-shipment. REFUND MUST NOT EXCEED ORIGINAL ORDER: Scalapay refund must not exceed original captured amount; automated refund must validate against original amount; automated excess refund creates refund exceeds payment error. ORDER EXPIRY IF NOT CAPTURED: Scalapay pre-authorized orders expire if not captured within merchant-configured timeframe; automated order management must capture promptly; automated delayed capture creates order expiry and payment not received.
Use Cases
- • Offering 3-installment BNPL to European shoppers from checkout agents
- • Capturing Scalapay authorization from European merchant fulfillment agents
- • Processing BNPL refunds from European order management agents
- • Confirming Scalapay payment events from European transaction agents
Not For
- • Non-European markets (Scalapay focuses on Italy, France, Germany, Spain, and nearby EU)
- • High-ticket BNPL (Scalapay optimized for fashion/lifestyle; Klarna for higher-ticket)
- • B2B BNPL (Scalapay is B2C consumer installment focused)

Agent Metadata
Known Gotchas
- ⚠ CREATE-THEN-CAPTURE TWO-STEP: Scalapay checkout creates order (gets redirect URL) then requires capture after consumer completes; automated checkout must follow create → redirect → capture flow; automated immediate post-create capture creates capture before consumer authorization
- ⚠ SUCCESS AND CANCEL URLS REQUIRED: Scalapay order creation requires successUrl and cancelUrl; automated integration must provide both URLs; automated missing URL parameter creates order creation validation failure
- ⚠ WEBHOOK SIGNATURE VERIFICATION REQUIRED: Scalapay webhooks include signature header; automated webhook processing must verify signature; automated unverified webhook acceptance creates spoofed payment event vulnerability
- ⚠ CONSUMER COUNTRY DETERMINES AVAILABILITY: Scalapay availability depends on consumer billing country; automated checkout must verify Scalapay availability for consumer's country; automated display of Scalapay for non-supported country creates payment option that fails at Scalapay redirect
- ⚠ MERCHANT CURRENCY MUST MATCH MARKET: Scalapay processes in local currency per market (EUR for most EU); automated payment amount must be in correct currency; automated USD or GBP amount for EU markets creates currency not supported error
