First request to Corefy API (MIN)

What it does: creates a payment-invoice; card data itself is collected and submitted separately by Corefy's checkout/SDK layer, not as part of this request. Justipay may return a 3D Secure challenge redirect depending on the card. CVV is required - non-CVV sales aren't supported on this flow.

customer is entirely optional and is only used to enrich the sale.

Extended request (MAX)

Why add extra fields (typical reasons): - Provide additional customer details for compliance/reconciliation - Positively influence conversion rate - Include optional fields required by your specific flow

No Constants are configured for this connector.

Options

• ignore_callback -> optional, boolean - for cascading to work correctly, excludes finalizing the payment from the asynchronous callback; Corefy then relies only on an active status request (reconciliation) to finalize it.
• save_provider_instant_token -> optional, boolean - if Justipay's response includes an instant token, Corefy stores it; confirm with your account manager whether a follow-up charge using this token is available for your account.
• generate_random_customer_data -> optional, boolean - if enabled and customer is missing from your request, Corefy automatically fills it in with generated placeholder data instead of sending nothing.
• transliterate_customer_data -> optional, boolean - transliterates customer fields to Latin before sending them to Justipay.
• transliterate_card_holder -> optional, boolean - transliterates the card's embossed holder name to Latin before sending it to Justipay (independent of the customer transliteration above).
• set_description -> optional, boolean - sends your transaction descriptor as the payment's description, instead of leaving it blank.
• duplicate_original_resolution -> optional, boolean - if Corefy's own resolution mapping can't classify Justipay's response, falls back to reporting Justipay's original resolution code instead of leaving it blank.

Refunds

This flow does not support refunds - use the Provider account if you need refunds.

Connect Provider account in Corefy Dashboard

Step 1 - Open connection form

Step 2 - Fill in fields and select settings

• Commerce ID
• API Key
• Secret Key for Callback
• API URL (optional)
• Send Metadata (optional)
• Test Mode -> (enable if you are using sandbox credentials)

First request to Corefy API (MIN)

What it does: creates a payment-invoice and redirects the customer to a Justipay-hosted page to complete the payment. The exact methods available (card, bank transfer, e-wallet, voucher, carrier billing, crypto, Apple Pay, Google Pay) depend on what's enabled for your specific Justipay account - check with your account manager.

customer is entirely optional - everything is only used to prefill the hosted form, it never blocks the sale.

Extended request (MAX)

Why add extra fields (typical reasons): - Provide additional customer details for compliance/reconciliation - Positively influence conversion rate - Include optional fields required by your specific flow

No Constants are configured for this flow.

Options

• allow_conversion -> optional, boolean - lets Corefy/Justipay automatically convert the transaction currency when the requested currency isn't directly supported, instead of rejecting the request outright.

Refunds

This connector does not support refunds on either account type.
