We are providing subscription app "定期購買" using Shopify subscription API.
We called billingAttempt mutaion API by scheduled subscription contract at 2021-07-14 21:00:00 (UTC+0).
Then, Shopify requests "subscription_billing_attempts/failure" webhook at 2021-07-14 21:00:22 (UTC+0) . But, Shopify created real payment.
It was specification? Or, bug?
Thank you for you question!
Did you receive an errorCode or errorMessage for the SubscriptionBillingAttempt?
You can query for those fields using the GraphQL API if you still have the SubscriptionBillingAttempt id, otherwise you can access the SubscriptionBillingAttempt using the billingAttempts field on the SubscriptionContract type if you have the SubscriptionContract id.
This page has more documentation on the SubscriptionBillingAttempt: https://shopify.dev/api/admin/graphql/reference/orders/subscriptionbillingattempt
Thank you for replying.
The errorCode was"unexpected_error" and the errorMessage was "Payment has already been made for this InvoiceID."
Also, I sent webhook headers and body logs on a contact form.
