Understanding Checkout

Checkout is the payment flow a viewer opens on your Tip page. It consists of a summary, payment method, fee calculation, and the Stripe payment field.

Flow

The viewer clicks a Support Box or checkout button.
Checkout opens with amount, username, message, and optional goal.
The viewer selects the payment method.
KALYIX calculates an estimate for Stripe fee, platform fee, and final amount.
The viewer decides whether to cover fees, if that option is active.
Prepare payment creates the Stripe session.
Only then does the Stripe payment field appear.
After successful payment, Stripe sets the status to paid.

Why Stripe Appears Only After Preparation

Stripe needs a prepared session for the specific payment attempt. This session depends on amount, payment method, fee coverage, message, username, and goal.

That is why the Stripe area is hidden first. The summary stays visible so the viewer can check amount and fees. Prepare payment creates the session and loads the matching Stripe field.

Why Stripe Disappears Again

If the viewer changes an important value after preparation, the old Stripe session no longer matches. KALYIX removes the Stripe field and requires a new preparation.

This happens when:

Change	Why preparation is needed again
Amount changed	Total amount, fees, and Stripe session change.
Payment method changed	Fee formula and allowed Stripe element change.
Fee coverage on/off	The total amount to pay changes.
Username, message, or goal changed	Payment data and assignment change.

This is intentional. Stripe should not continue with old data when the summary already shows new values.

Payment Method

In checkout, the viewer can select the payment method before payment. KALYIX uses this selection for the fee estimate and passes the method to Stripe checkout.

Available in checkout:

Method	Note
Card	Base method for classic card payments.
PayPal	Dedicated fee assumption for PayPal through Stripe.
Klarna	Dedicated fee assumption for Klarna.
Amazon Pay	Dedicated fee assumption for Amazon Pay.
Link	Stripe Link.
Google Pay	Wallet payment through card.
Apple Pay	Wallet payment through card.

Fees In The Summary

The summary shows:

Row	Meaning
Amount	Base amount the viewer wants to support with.
Stripe Fee	Estimated Stripe fee for the selected method.
Platform Fee	KALYIX platform fee.
Approx. received	Estimated amount after fees.
Total	Amount the viewer pays.

The Stripe fee is an estimate. Final values can differ because of international cards, currency, card type, or payment-method details.

Fee Coverage

When fee coverage is active, KALYIX increases the total amount to pay by the estimated fees. The goal is for the creator to receive closer to the intended base amount.

Important: fee coverage uses an estimate. The final amount can still differ if Stripe later calculates higher real fees.

Possible Checkout Errors

Error / label	Meaning	What to do
`Checkout could not be started`	The payment intent or Stripe session could not be created.	Check amount and connection, then try again.
`Embedded Checkout could not be started`	Stripe could not prepare the embedded checkout field.	Prepare checkout again. If it remains, check the Stripe connection.
`Payment could not be confirmed.`	Stripe rejected or canceled confirmation.	Check payment details and try again.
Stripe keeps loading	The Stripe element could not finish loading.	Close checkout, open it again, and prepare it again.
Stripe disappears after a change	Amount, method, or fee coverage was changed.	Click `Prepare payment` again.
Payment stays `pending` afterward	Stripe has not finally confirmed yet.	Check the Payments page again after a short time.
Payment is `failed`	Payment was not completed.	The viewer starts checkout again.

After Payment

When Stripe reports paid, the payment becomes visible in Payments. If alert rules react to paid payments, this can create an alert for OBS.
