👋 happy to help

Its important that we get to use both creditcard and sepa (from ideal and bancontact)

We are also working on a customer portal to have customers update their subscription and/or payment method.

[languid haven]

What is the best way to handle this? Should we create a one time / subscription checkout or use the setup route and charge the customer from our application?
You can use Checkout in subscription mode for this

[languid haven]

you can use our hosted Customer Billing Portal for this instead

[analog gust]

Will Stripe automatically do the next charge after X days?

[languid haven]

yes

[analog gust]

Is it possible to add new products to the subscription via API? Or change the frequency?

@shadow hemlock FYI

[languid haven]

yes

https://stripe.com/docs/billing/subscriptions/upgrade-downgrade

[analog gust]

Then we should send the products on the invoice.paid webhook?

[languid haven]

yes

it's explained here https://stripe.com/docs/billing/subscriptions/webhooks

[analog gust]

Any other suggestions or tips? 😁💪🏻

[languid haven]

for subscriptions always use invoice.paid

[analog gust]

For one time?

[languid haven]

no for subscriptions

[analog gust]

Yea, but which one should we use for onetime?

We have an option in our builder to only do a one time purchase.

[analog gust]

Do we only use checkout.session.completed for onetimes or also for the first shipment of the subscription?

[languid haven]

when you receive the checkout.session.completed if the mode is subscription, I would say you ignore the event
