Webhook create via REST API not working

[cywareinc]

Hi,

When I manually create a web hook through my development store's  [Settings / Notifications / Webhook] screen, my HMAC calculation matches.  For this scenario, I am using the key displayed at the bottom of the screen.

However, when I create a web hook through the REST API, the same exact code for HMAC calculation fails.  Here are the steps I take:

1) Delete all manually created web hooks

2) Create a web hook using REST

3) Use the "API Secret Key" in my application "App Setup" screen in place of the key provided by manually created web hooks.

I am receiving the hook in my web server which means the web hook has been successfully created.  Seems like the "API Secret Key" that I am using is wrong. 

Where can I find the correct key to use?

Any help would be greatly appreciated!  Thank you.

For the benefit of anybody going through the same problem, I finally figured out the correct key to use. 

I am using a private Shopify application so the web hook verification key can be found in my development store's Apps section as opposed to the Partner Dashboard App screen.
