hello, you want this: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-subscription_data-trial_period_days

[grand needle]

Thanks but how do i implement it in here ? ``` app.post("/create-checkout-session", async (req, res) => {
const domainURL = process.env.DOMAIN;
const amount = process.env.SITE_PRICE_ID;
const { priceId } = req.body;
let customerName = req.body.customername;
let customerDesc = req.body.customerdesc;
let customer = await stripe.customers.create({
name: customerName,
metadata: { entreprise: customerDesc}
});
try {
const session = await stripe.checkout.sessions.create({
customer: customer.id,
phone_number_collection: {
enabled: true,
},
billing_address_collection: 'required',
mode: "subscription",
payment_method_types: ["card"],
line_items: [
{
price: priceId,
quantity: 1,
},

    {
      price : amount,
      adjustable_quantity:{
        enabled:true,
        minimum: 0,
        maximum:10,
      },
      quantity: 1,
    },
  ],
  automatic_tax: {
    enabled: true,
  },
  success_url: `${domainURL}/success.html?session_id={CHECKOUT_SESSION_ID}`,
  cancel_url: `${domainURL}/canceled.html`,
  
});
return res.redirect(303, session.url);

} catch (e) {
res.status(400);
return res.send({
error: {
message: e.message,
}
});
}
});``` ?

[hearty locust]

are you the developer building the integration?

[grand needle]

Yeah

[hearty locust]

the API ref link shows what you need to pass, you have to pass subscription_data.trial_period_days

[grand needle]

Yeah but what is the syntax ? How do i add my 30 days here ?

[hearty locust]

subscription_data is a hash
so

...
}```

and inside that you pass `trial_period_days: 30`

[grand needle]

Ok fuck me. In my code uphere, i have 2 products, it possible to assign this behaviour (trial 30 days) to the first one (price: priceId?)

[hearty locust]

no it applies to the whole Subscription, you cannot give trial only on one of the products

[grand needle]

ok and i have a last question ``` line_items: [
{
price: priceId,
quantity: 1,
tax_behavior: "exclusive",
},

    {
      price : amount,
      adjustable_quantity:{
        enabled:true,
        minimum: 0,
        maximum:10,
      },
      quantity: 1,
      tax_behavior: "exclusive",
    },
  ],
  subscription_data:{
    trial_period_days:30
  },
  automatic_tax: {
    enabled: true,
  },``` i wanted to add tax to my product but it says "{"error":{"message":"Received unknown parameter: line_items[0][tax_behavior]"}}" i activated tax on my dashboard also

[hearty locust]

so tax_behavior is not a parameter on line_items if you see the API ref

instead it is inside the price_data hash
https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-line_items-price_data-tax_behavior

which you are not using, you are passing a Price ID (for a Price you already created)

you would have to update the Price via the Dashboard or API and update tax_behavior on that

[grand needle]

And there is no way to get trial subscription only for one item during checkout ? Thanks mate !

[hearty locust]

there isn't no

[grand needle]

Ok thanks mate, have a good dayt
