Webhook suddenly timing out

[LucaHolland]

Hi there!

We have a inventory/update webhook subscription as part of our app that has been running fine until a few days ago, when it suddenly started timing out. Now all of the inventory/update webhooks are timing out. But, we haven't changed any of the code.

The script responds with '200 OK' as soon as it has verified the webhook and then goes on to do the rest of the functionality ( which does involve a call to the Shopify API)

Has there been a change in the way the webhook timing works? Is there something that we can do to fix this?

Hello, @LucaHolland! Welcome to the community forums.

There has not been any change to webhook delivery in the past few days. In fact, we specifically do not deploy any code over the BFCM (Black Friday / Cyber Monday) period to be sure that everything stays consistently reliable over the most important event of the year for our merchants.

I am not sure what could prompt a sudden time out of your webhooks (network issue? hosting issue?). If you send me a private message with your application's api client ID, and the topics that you are having issues with, I can take a look and see if there is any issue on our side, however unlikely.
