Attribute Pay records to user using email address

[gczh]

At the moment, we use payment links generated on Stripe for our pricing tables hosted on a landing page builder.

Customers create a new subscription by paying using those payment links (which is different for each Subscription plan)

We're using Pay gem which register the Stripe webhook events, but they don't attribute the subscription and other related data to the User in our app through their email address.

The email address is used on the payment, and on our app.

Is there anyway to sync Stripe data (subscription, payments, etc) with the email address without hacking around too much? Or maybe, is there a better flow I can use here?

You can add a custom webhook to create the Pay::Customer by email address and then sync the subscription.

Ahh, got it – so I'd have to use a custom webhook. Appreciate you pointing me in the right direction 🙏

When a payment is made through a payment link, there are quite a number of webhook events. Which one should I be using? I'm assuming invoice.paid as that means the payment was successfully made for the subscription?

As for syncing the subscription, would that be something like the following?

user = User.find_by(email: email)

# manually pulling the customer for now to test how I'd sync the stripe customer from webhook to a Pay Customer
stripe_customer = Stripe::Customer.list(email: user.email, limit: 1).first

# Create a pay customer
Pay::Customer.create(
  owner: user,
  processor: :stripe,
  processor_id: stripe_customer.id
)

# Sync the subscription
user.payment_processor.sync_subscriptions

I tried the above but when I do user.payment_processor.subscriptions, I get an empty array.

Also, would there be an issue if say, a user has already created an account with the email address?

To create the Pay::Customer, you actually want to use:

user.set_payment_processor(:stripe, processor_id: stripe_customer.id)

We use STI now for the Pay::Customer model, so without setting the type column, it may not work right.

An easier option might be to create the Stripe Customer with Pay and then embed the pricing table including their session: https://docs.stripe.com/payments/checkout/pricing-table#customer-session

Then I think the webhooks will take care of the rest.
