This user isn’t a Stripe customer

[handplant]

I'm logged into Craft CMS and making a checkout using the following code:

{{ tag('a', {
  href: stripeCheckoutUrl(
    cartItems,
    currentUser ?? false,
    'thank-you?session={CHECKOUT_SESSION_ID}',
    '/?cancelled=true',
    {}
  ),
  text: 'Checkout',
  class: 'btn btn--xl',
}) }}

I’m wondering why the user is recorded as a guest in Stripe, and in the Craft backend, it shows "This user isn’t a Stripe customer." Shouldn’t this be linked? Or have I overlooked something?

Webhooks are running with the Stripe CLI.

Thank you!

Hi, thanks for reaching out!

It looks like the product you purchased is a one-off product, not a recurring one (not a subscription). By default, when purchasing a one-off product, Stripe will create a guest customer. As per https://docs.stripe.com/api/checkout/sessions/create#create_checkout_session-customer_creation, you can change that behaviour in 2 different ways:

• you could set customer_creation to always
  for example:

{% set params = {} %}
{% if not currentUser %}
  {% set params = params|merge({'customer_creation': 'always'}) %}
{% endif %}
{{ tag('a', {
  href: stripeCheckoutUrl(
    items,
    currentUser ?? false,
    craft.app.request.getAbsoluteUrl() ~ '?session={CHECKOUT_SESSION_ID}&test=value',
    craft.app.request.getAbsoluteUrl(),
    params
  ),
  text: 'Checkout',
  class: 'btn btn--xl',
}) }}

• or have the post-purchase invoices enabled, in which case a Customer will be created even for the one-off purchases; you’d do that by setting invoice_creation.enabled to true;
  in this case, the params would be:

{
  'invoice_creation': {
    'enabled': true
  }
}

Please note that some parameters are only allowed in certain modes. For example the invoice_creation parameter is only allowed when making a one-off purchase and will throw an error when used when purchasing a recurring one (when purchasing both one-off and a recurring product in a single checkout, the mode is set to subscription).

I hope this clarifies things!

I'll close this now, but feel free to reach out if you run into any further issues.
