Billing success webhook is not being called for some shops since updating API in July & Aug

[Denn]

Our billing success web-hook as always been properly called by Shopify when billing attempts are successful.
But we noticed in the past two months since July that some of our customers shops don't receive a billing success web-hook at all. On later investigation, the billing attempt was ready, and the order came through. So we have had to manually restart subscriptions for these shops. 

We have been unable to replicate this issues in our test environment and thus cannot figure out what the issue is from our side.

Is there a way to check whether a web-hook subscription is being delivered properly? Do we need to re-register web-hooks after updating to the latest API? 

API version 2022-07

If there's any I'll greatly appreciate.

We also confirmed that webhooks are registered for these shops with the new API version.

Hello @Denn,

Yes, check the Webhook metrics report in your Partner Dashboard.

If this is still unresolvable on your side with the information in the report, please DM me with specific details so we can take a deeper look.

Updating the webhooks to an API version involves registering them under the desired version as per this tutorial. To my understanding this update should not be a reason for you to not receive the billing success webhook inconsistently between shops.

Please keep us posted.

Best,

Juan
