I have defined a product in Stripe that I want to set up as a 7 day free trial and then charge the customer (unless they cancel beforehand)
Using a custom Nodejs function via Firebase - I get the following error:
Missing value for stripe.confirmCardPayment intent secret: value should be a client_secret string
My front-end functions:
const createSubscription = async () => { setProcessing(true); setWait('PLEASE WAIT'); try { // create a payment method const paymentMethod = await stripe?.createPaymentMethod({ type: "card", card: elements?.getElement(CardElement), billing_details: { name, email, }, }); // call the backend to create subscription const response = await fetch("https://XXX.cloudfunctions.net/tplannersubscription", { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ paymentMethod: paymentMethod?.paymentMethod?.id, name, lname, email, priceId }), }).then((res) => res.json()); const confirmPayment = await stripe?.confirmCardPayment( response.clientSecret ); };
and my node function:
cors(request, response, async () => { // create a stripe customer try { if (request.method != "POST") return response.status(400); const { name, email, paymentMethod } = request.body; // Create a customer const customer = await stripe.customers.create({ email, name, payment_method: paymentMethod, invoice_settings: { default_payment_method: paymentMethod }, }); // const priceId = request.priceId; // Create a subscription const subscription = await stripe.subscriptions.create({ customer: customer.id, items: [{ price: "price_1KZ3nTGxUje7SlyIDUfIXkr3" }], payment_settings: { payment_method_options: { card: { request_three_d_secure: "any", }, }, payment_method_types: ["card"], save_default_payment_method: "on_subscription", }, payment_behavior: "default_incomplete", trial_period_days: 7, expand: ["latest_invoice.payment_intent"], }); // Send back the client secret for payment response.json({ message: "Subscription successfully initiated", clientSecret: subscription.latest_invoice.payment_intent.client_secret, subID:subscription.id }); } catch (err) { console.error(err); response.status(500).json({ message: "Internal server error" }); } });
If I take out the Trial_period_days then it works fine, but if I include it it returns the error as mentioned above.
When you create a trial subscription, a PaymentIntent is not created because no payment is currently required.
Instead, SetupIntent can be used to collect payment method details. You can extend
pending_setup_intent
