Our Webhook has stopped working

[SiyonaS]

We have a private app created in shopify and the moment we have received the app update notification, our webhook stopped working.

Can you please help?

Does the webhook subscription still exist or has it been deleted?
Have your tried testing the webhook being sent to another location in case it's your tech stack being the problem?

[SiyonaS]

We also have few other webhooks which are working fine.

Only the one which uses this API Key 0a53154f5292779574ea039e1ca14d26 is not working.

[Jason]

First step is confirming that the webhook subscription still exists.
Since it's bound to that key, you should first check to ensure it has not been deleted. If it has, that quickly explains why you're not seeing anything.

[SiyonaS]

How can we check that? also to add all our other webhooks are working perfect.

[Jason]

Do a GET request with that key and see what comes back. 

See the docs:
https://shopify.dev/docs/admin-api/rest/reference/events/webhook#index-2021-04

GET /admin/api/2021-04/webhooks.json

[SiyonaS]

Sure I will try this.

Also, we are getting this message in our private apps section,

'Some of your private apps may not work as expected because they’re calling unsupported APIs'.

And this app credentials is called in our salesforce code, when we do a request, is send bake bad data error.

[Jason]

Sounds like you're using old and unsupported versions of the API.
Also quite possible this relates to your webhook issue depending on the API version that was requested.

[SiyonaS]

That sounds fair enough.

Can you please help us, as to how can we have the latest version of app?

Where can we make this change? 

[SiyonaS]

Also as suggested earlier, we tried the GET method and this is what we received in our debug logs,

16:31:03:268 USER_DEBUG [82]|DEBUG|calloutResponse::System.HttpResponse[Status=Bad Request, StatusCode=400]

Hi Siyona!

We're experiencing a similar situation that started about the same time as yours. Our Shopify store has stopped communicating with our Learning Management System (LMS). We've updated our webhooks to the current API version but it is still not working...are you still having troubles?

[SiyonaS]

I was able to resolve the issue by specifying  a location_id when creating fulfillments

Thank you for you help @JasonW .
