Get payment method details from confirm setup intent response in Stripe JS

Question

Hello everyone and good night :)

I am trying to obtain the payment_method details i.e. card and billing address details from the stripe.confirmSetup call in javascript. I have tried to expand the payment_method parameter with no luck so far. I can retrieve the needed details with a subsequent api call with the newly created payment method but am trying to avoid that if possible.

My code is as follows:

    const form = document.getElementById("payment-form"); 
    const stripe = Stripe('pk_test.....s'),
    form.addEventListener('submit', async (event) => {
      event.preventDefault();
      stripe.confirmSetup({
        clientSecret : "seti_...",
        redirect : "if_required",
        confirmParams : {
          return_url : "example.com/returnURL.php"
        }
      }).then(function(result){
        if(result.error){
          document.getElementById("error-message").textContent = result.error.message;
        }else{
          console.log(result.setupIntent);
        }
    });

Thanks for your help! - Midgeypoo

There is not a way to pass an expand parameter on a SetupIntent confirmation. When you pass this, you'll get an error stripe.confirmSetup() parameter: expand is not a recognized parameter. To get data from the payment_method, you can make a separate request to retrieve the SetupIntent, on the client side using the expand parameter. There are a subset of properties that will be returned when using a publishable key with retrieving the Setup Intent which are marked with RETRIEVABLE WITH PUBLISHABLE KEY in the API document and payment_method is one.
