Webhook after a successful payment
Stripe will trigger invoicing only after the order is paid. Events will be processed idempotently so a retried webhook cannot create a duplicate invoice.

Automatic KSeF invoices after Stripe payments
We are working on a Stripe integration for KSeFGPT. Once released, the buyer pays on the merchant website, Stripe confirms the payment with a webhook, KSeFGPT prepares an FA(3) invoice, submits it to KSeF, and stores the status with the KSeF number.
Stripe Checkout

The payment starts invoicing, but the invoice is generated and submitted to KSeF by KSeFGPT.

Planned flow
From the customer page to the KSeF number
1
The buyer pays on the seller website through Stripe.
2
Stripe sends information about the paid transaction.
3
KSeFGPT prepares the invoice in .xml format and submits the document to KSeF.
4
The buyer lands in Contractors, and receives a PDF invoice with the KSeF number by email.
5
Your invoices paid through Stripe are visible in KSeFGPT under Invoices -> Outgoing.
Stripe data mapped to FA(3)
KSeFGPT will collect buyer data, line items, amounts, currency, taxes, and product mappings. Missing data will go to a queue for manual completion.
Invoice submission to KSeF
After FA(3) XML validation, KSeFGPT will submit the invoice to KSeF on behalf of the seller, store the processing status, and link the transaction to the returned KSeF number.
KSeF invoice automatically after a Stripe payment
The buyer pays by card or another Stripe method, and KSeFGPT turns the paid transaction into an FA(3) invoice and submits it to KSeF without manual data entry.
