Hi there!

#

Do you pass an existing customer ID when creating the Checkout Session? https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-customer

copper warren Oct 26, 2022, 10:42 AM

#

Yes!!

#

I have the customer ID

#

So why don't you update the customer just before creating the Checkout Session?

copper warren Oct 26, 2022, 10:49 AM

#

Do I need to use the webhooks events to do that? I mean when customer created -> make the post to update the customer and assume that this is always after the checkout session is created? I use the stripe checkout with firebase extension

#

You could, but you don't need to use webhook event. In your existing code, just before creating the Checkout Session, write some code to update the customer.

#

Nice!! But here I dont have the customer ID

#

#

then I would need to get it

#

but do you mean here, right?

#

but I dont know if the customer is already created here

#

I though you already had a customer ID. If needed you could create one, and then pass it when you create the Checkout Session.

#

Here's the parameter to pass a customer ID when creating a Checkout Session: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-customer

#

But taking a step back, can you clarify why exactly you need to update the customer before the payment is finished?

copper warren Oct 26, 2022, 11:12 AM

#

Nice!! Yes, I need to pass some metadata on the customer (user name and user tax ID) to integrate with e-notas

#

and when the customer is charged, the charge object must be send with this metadata

young mural Oct 26, 2022, 11:17 AM

#

Got it! Then yes:

First create the customer
Then create the Checkout Session with that customer
And then listen to the checkout.session.completed event to update the charge object

copper warren Oct 26, 2022, 11:24 AM

#

Thank you!! But I think I wont need to update the charge object, because if I update the customer object, when the customer is charged the charge object will already have the medatada sent, right?

#

If your customer has some metadata, then that metadata won't be added to the Checkout Session or PaymentIntent or Charge. It's up to you to update these objects with metadata if needed.

#

Ok, thank you!!
