Webhook Create Failure / Address Weirdness

[Jerod Santo]

I am trying to create a Webhook via the Ruby gem and I'm getting conflicting failure errors.

The first time through:

ShopifyAPI::Webhook.create(topic: "products/update", address: "http://example.com", format: "json")

This fails with: @messages={:address=>["is not allowed"]}

The second time through, sans address:

ShopifyAPI::Webhook.create(topic: "products/update", format: "json")

This fails with: @messages={:address=>["can't be blank"]}

I would definitely expect address to be required, so maybe I'm not formatting the address properly and the "is not allowed" error message is too vague for me to be sure?

Any help would be much appreciated!

Can't use example.com, simple as that :)

If you use a "real" host it should work as expected.

Cheers, Dennis

This is a *really* good question to place on stack overflow.  While I'll give you the answer, if you could copy-pasta it over to SO that would be fabulous!

I believe we have a blacklist of naughty domains, some of those include localhost and example.com

If you're looking to test the webhooks, use a proxy service and pass in that domain as your webhook url.

With regard to proxy services, give this article a read for some examples: http://www.shopify.com/technology/3931292-webhook-testing-made-easy

For anyone interested in the full list of banned domains for webhook subscriptions, here's the array of regexes we use:

[/^(127|192|10|0)\./, /localhost/, /^(\w+\.)*internal$/, /^(\w+\.)*(example|shopify|myshopify)\.com$/]

Thanks everybody. That helps.

One suggestion would be to return a more helpful error message, e.g. - "blacklisted domain" instead of simply "is not allowed".
