This is my code and. After firng this one i'm getting below response but still webhook not registered.

                (
                )
        )
)

Can anyone review my code?

Hi,

Have you queried the webhooks endpoint to check i.e. GET /admin/webhooks.json ? Webhooks created by your app do not show up in admin UI as they're bound to your app, not the "admin app".

Sadly I cannot offer any review on PHP because I am not a PHP developer, though looking at the cURL it all looks okay. So above is just a suggestion to double check.

Best wishes!

[Pratham_Jani]

yes, i did queried as you specified. 

But its still not showing our registered webhooks in json format. It shows only from the admin side manually. 

Any possibilities?

[KarlOffenberger]

Strange because the response you mention clearly shows the webhook ID so I'd assume it was created successfully. Could you try the same POST operation using a REST client such as Postman or Insomnia, using the same API credentials as your app and making sure you have cookies disabled in your request - just to narrow down the possibilities whether it's the API request itself, or maybe something in the PHP client request.

[Pratham_Jani]

I tried in Postman also. But result was same!

i don't know wthat to do now!

[KarlOffenberger]

So again, just to confirm, POST /admin/webhooks.json with

{
  "webhook": {
    "topic": "app/uninstalled",
    "address": "https://test.requestcatcher.com/",
    "format": "json"
  }
}

via a REST client doesn't work?

I've just tested the endpoint and was able to create and confirm the webhook was registered.

[KarlOffenberger]

If you're still having no luck with any of that, I suggest you post the X-Request-Id from your response header so that Shopify staff can look in to the details of the request.

[Pratham_Jani]

OK i'm getting you in REST. Can you post your flow with you've tried!. 

[KarlOffenberger]

No special flow, just 1 single request like I posted above.

[Pratham_Jani]

i'm firing with this flow.

https://{username}:{password}@{shop}.myshopify.com/admin/webhooks.json

Is it correct?

[KarlOffenberger]

curl --request POST \
  --url https://store.myshopify.com/admin/webhooks.json \
  --header 'authorization: Basic XXXXXXX' \
  --header 'content-type: application/json' \
  --data '{
  "webhook": {
    "topic": "app/uninstalled",
    "address": "https://test.requestcatcher.com/",
    "format": "json"
  }
}'

is this headers are correct?This is my request bulk.

@KarlOffenberger

Hey now it's working like a charm, I've checked with the request catcher and I got a response. But still, one thing is remaining that now I've to get that response in my app file e.g. /delete.php.  So for that, I'm finding receiving the code if you can help me with that it'd be Veeery appreciable for me. :))))

[KarlOffenberger]

Hey again. Sorry, but I cannot help you out with PHP because it's simply not a language I know.

The process of creating a webhook handler on your side is pretty straightforward:

1. Must be via HTTPS
2. Must be a POST endpoint
3. Should verify HMAC
4. Should return 200 response
5. Should return quickly

General advice and gotchas for webhooks are:

• Don't process them immediately - receive > queue up > respond 200. Work through your queue separately.
• Deduplicate - you will be getting dupes for a number of reasons known and unknown. Handle them gracefully.
• Don't rely on webhooks being reliable. Assume they're not. Program defensively.
• Don't rely on your app being reliable. It isn't. There isn't such a thing as bullet proof code. Handle re-registration and import.

During development use any of the free or paid localhost tunnelers. Makes life easier.

Good luck!
