App Fee Money with Checkout API - createPaymentLink

foodmission — Sun, 21 Sep 2025 12:33:50 GMT

I am using the following in a Square sandbox setting. How can I be assured that this is applying the correct intent - Pay merchant via Main Location ID and apply a application fee. When I view the sandbox transactions it is not clear that this is being applied. Where can I access the split amounts in a Sandbox environment?

const response = await squareClient.checkoutApi.createPaymentLink({

idempotencyKey: crypto.randomUUID(),

order: {

locationId: merchantLocationId,

lineItems: orderItems,

referenceId: orderId

checkout_options: {

app_fee_money: {

amount: parseInt(orderDeliveryPrice * 100, 10) + parseInt(orderServiceCharge * 100, 10),

currency: 'GBP'

redirect_url: "xxxxxxxxxxxxxxxxxxxx"

}

});

Hey @foodmission, this is a seller community so to most of us that could be an alien language 😂

I’d recommend checking out the developer forums [LINK] as those guys are far more likely to be able to help!

That's correct, @foodmission - we don't provide API support in this particular Community, apologies.

The developer forum linked by Sam is the best place to raise this query.

You can also contact our support team who can pass your case directly to a Developer Success Engineer who can better help answer your questions

I hope this helps!
