I do not receive the metadata when creating a checkout session

[EnriqueRapelaDeveloper]

Describe the bug

I have an API with Ruby on Rails, and I'm creating a checkout session to make a payment. I leave you the code block below:

    session = Stripe::Checkout::Session.create(
      payment_method_types: ['card'],
      line_items: [{
        price_data: {
          currency: 'eur',
          product_data: {
            name: 'Invitación de boda'
          },
          unit_amount: 8000 # Put the correct amount or set in the database
        },
        quantity: 1
      }],
      mode: 'payment',
      success_url: "#{@base_url}/#{@payment_intent.uid}/confirm_payment", # FRONT URL FOR SUCCESS REDIRECT
      cancel_url: "#{@base_url}/#{@payment_intent.uid}/cancel", # FRONT URL FOR FAILED REDIRECT
      metadata: {
        uid: @payment_intent.uid
      }
    )

This is what is created in the dashboard:

{
  "metadata": {
    "uid": "ddf0f536-8e8f-4d58-8eb8-133c1858530f",
    "lol": "holaaa!"
  },
  "mode": "payment",
  "line_items": {
    "0": {
      "price_data": {
        "unit_amount": "8000",
        "currency": "eur",
        "product_data": {
          "name": "Invitación de boda"
        }
      },
      "quantity": "1"
    }
  },
  "cancel_url": "https://few-hands-cut.loca.lt/ddf0f536-8e8f-4d58-8eb8-133c1858530f/cancel",
  "success_url": "https://few-hands-cut.loca.lt/ddf0f536-8e8f-4d58-8eb8-133c1858530f/confirm_payment",
  "payment_method_types": {
    "0": "card"
  }
}

I see this from Developers/Registrations -> POST /v1/checkout/sessions

Then I get a callback when you complete the payment but I get empty metadata, I'll show you an example:

Do you know what I'm doing wrong to not receive the metadata in the webhook?

To Reproduce

UP!

Expected behavior

I need to receive the metadata with the UID in the stripe webhook, to be able to locate the payment to which that webhook request refers.

@EnriqueRapelaDeveloper Github issues are limited to bugs or feature requests with the SDK itself. Your question is an integration support question better directed at our support team: https://support.stripe.com/contact

To unblock you though, the metadata you set is on the Checkout Session but the Event you looked at is payment_intent.succeeded which describes a PaymentIntent. Those are two completely separate API resources with their own metadata so it's expected that they don't match. You should be listening for checkout.session.completed instead as the Event.
If you really want metadata on the PaymentIntent, you need to configure it on creation using the payment_jntent_data[metadata] parameter.
