@theodufort Hey, I was just facing the same problem. Looks like the trial period days field is a little hidden.

let checkoutSession = await stripe.checkout.sessions.create({ customer: customer.id, success_url:"https://mycompany.com", line_items: [{price: priceId}], allow_promotion_codes: true. mode: "subscription", **subscription_data: {trial_period_days: 7}** });

The trial_period_days is hidden in the subscription_data field indicated in the API docs here: https://stripe.com/docs/api/checkout/sessions/create.

Hope that helps!
