Add support for Embeddable Pricing Tables

[scalaxofaiur]

Hello i found that Cashier currently doesn't work with Embeddable Pricing Tables

https://stripe.com/docs/payments/checkout/pricing-table

Currently, when the user creates a subscription with pricing tables, Stripe creates a new customer.

Customer.subscription.created webhook doesn't seem to be able to connect the new customer to laravel user.

Stripe gives the chance to attach a "client-reference-id" that could be used to pass the authenticated user id (or better an encrypted string that identify the user) back to cashier with checkout.session.completed webhook

Ah sorry that's something else. I'll have a look.

Right now I don't see an immediate way to make this work with Cashier. We solely rely on the customer.subscription.created and/or customer.subscription.updated webhooks to create the subscription and attach it to the user. There doesn't seems to be a way to let checkout attach this client_reference_id to the subscription as well. Therefor, from what I can tell, this isn't possible.

I don't have the time at the moment to deep dive into this to find workarounds but would appreciate PR's or other insights if there are any. Thanks

Thanks @driesvints, at the moment i decided to avoid using Embeddable Pricing Tables and have implemented one on my own by reading products data directly from Cashier facade.

Should i have more updates i will surely write them here.

Thanks.

Going to close this one as it's not likely this can be resolved.
