I’m attempting to write a custom app for our store to tie in our inventory. I have created a web service that captures the different webhook messages for orders/create, orders/update, orders/cancelled, and orders/delete. Create, Update, and Cancel all fire correctly when clicking the Send test notification button next to each webhook in the shop Notifications section. However, when I click the Send test notification button for the orders/delete webhook, it generates a 500 error within the Shopify admin.
My URL is wired up through ngrok, and I triple-checked that everything is spelled correctly. The request never hits ngrok, so it never gets forwarded to my app. If I fire the POST using the same URL (copied + pasted from Shopify) using Postman, it hits ngrok and gets forwarded to my app. Is there something funky with the orders/delete webhook?
