In your code, I don't see anywhere that tax_calculation is defined.

You didn't declare tax_calculation in your code

[signal crag]

app.post('/update-payment-sheet', async (req, res) => {
const calculation = await stripe.tax.calculations.create({
currency: 'usd',
line_items: [
{
amount: req.body.amount,
reference: 'L1',
},
],
customer_details: {
address: {
line1: '123 Dear Road',
line2: '',
city: 'Acme',
state: 'AL',
postal_code: '85255',
country: 'US',
},
address_source: 'shipping',
},
expand: ['line_items.data.tax_breakdown']
});

const paymentIntent = await stripe.paymentIntents.update(
    req.body.paymentIntentID,
    {
        amount: calculation.amount_total,
        metadata: {tax_calculation: calculation.id}
    }
);
console.log("update payment sheet req",req.body)


res.json({
  total: calculation.amount_total,
  tax_amount: calculation.tax_amount_exclusive,
  client_secret: paymentIntent.client_secret
});

//console.log("update payment sheet res",res.body)

});

I see you setting tax_calculation in the metadata. In you webhook event code, you should retrieve the tax_calculation from the metadata of the Payment Intent object in the event first before using it

[signal crag]

Can you assist with how to do that?

[gloomy gale]

In https://dashboard.stripe.com/test/events/evt_3Q601AJ15oFjjfNB0w5dg3rH, you can see that tax_calculation was included in the metadata.

You'd need to retrieve the metadata to get the tax_calculation from the paymentIntent object in your code.

This will look something like:

paymentIntent.metadata.{{the-metadata-key}}

[signal crag]

Ok thank you for the code hint, very helpful! I will try and see if I can incorporate

I tried this code

const transaction = stripe.tax.transactions.createFromCalculation({
calculation: paymentIntent.metadata.tax_calculation,//'{{TAX_CALCULATION}}',
reference: paymentIntent.id,//'{{PAYMENT_INTENT_ID}}',
expand: ['line_items'],
});

and didnt get an error

[gloomy gale]

Looks good to me! If the transaction is created successfully, then you will be all good

[signal crag]

If i go to export transactions its not showing in the download... would it appear here in Test Mode? Or is there another way to check if the tax transaction posted successfully?

[gloomy gale]

You can check the request history: https://dashboard.stripe.com/test/logs?method[0]=post&method[1]=delete&direction[0]=connect_in&direction[1]=self

[signal crag]

Screenshots attached, do you think it posted the tax transaction successfully?

[gloomy gale]

If the status code is 200, it means the request was made successfully.

In your code, the a transaction object is returned, this also means that a tax transaction is created successfully

[signal crag]

Yay! Thanks for your help!
