Check paddle billing webhook

[lonhtm]

I have been playing with pay and paddle billing for a week. Till now, I can now have a inline checkout in a turbo_frame. But all the subcriptions create by using paddle.js is not sync with the database. I think the webhook might not be properly config. Can you guy advices where should I have to dig deep to solve the issue?

Thank you

I've been facing the same issue and while I'm debugging I will try to update here, so we can collectively find out the reason.
In my case, my model is Team and when I create one new team, my Pay::Customer data does not have the processor_id:

Pay::Customer:0x00007f8913a3f428
 id: 3,
 owner_type: "Team",
 owner_id: 3,
 processor: "paddle_billing",
 processor_id: nil,
 default: true,
 data: nil,
 deleted_at: nil,
 created_at: 2024-01-15 13:37:21.303918 UTC,
 updated_at: 2024-01-15 13:37:21.303918 UTC,
 stripe_account: nil,
 payment_method_token: nil>

Since both charges and subscriptions require the `customer_id for finding the costumer as:
https://github.com/pay-rails/pay/blob/main/lib/pay/paddle_billing/subscription.rb#L34
https://github.com/pay-rails/pay/blob/main/lib/pay/paddle_billing/charge.rb#L22

That will fail to update the record. Now comes the question: If I'm creating a new record, and customer_id is the Paddle customer ID, how come we require it at this point?

[deanpcmad]

In order for a Paddle Customer to be created, you need to run the customer method. Like so:

# Set the payment processor
@user.set_payment_processor :paddle_billing

# Create the customer on Paddle
@user.payment_processor.customer

This creates the customer on Paddle and sets the processor_id on the Pay::Customer record

Thanks, that solved the problem!

Just wanted to add a quick follow up to this. I have the padding billing webhooks working as show in the documentation and I can see a successful subscription.

How can I get access to the payment method the customer is using though? I can't seem to find this information no matter what I try, and I can't see any entries into my pay_payment_methods table.

As everything for subscriptions is handled via webhooks with paddle billing I'm wondering if there is something I'm missing?

hi @deanpcmad, I've got payment methods being added to my database now after your PR which is great, thanks for sorting that bug out.

When I update the payment method I can see it adds another entry into the pay_payment_methods table but it doesn't update the customers default_payment_method when I try and access it like this:

<%= @user.payment_processor.default_payment_method %>

To get the last payment method I have to do this:

<%= @user.payment_processor.payment_methods.last %>

Is this the intended behaviour? If so, is there a way for me to use the paddle billing webhooks so that the last payment method added becomes the default?

[deanpcmad]

Glad to hear that's fixed it. That update should also make the payment method the default, but you can use make_default! to force a payment method to be default

hi @deanpcmad I'm definitely not seeing the default card being updated when I add a new one. I can see in my database there are 3 cards for the same person and they all have true set to the default column
