I'm trying to create a new ZIS integration with the following
```
url="https://$subdomain.zendesk.com/api/services/zis/registry/risk_found"
curl "$url" \
-d '{"description": "some description"}' \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-v -u "$email_address:$password" -X POST
```
where $email_address is my email address + "/token" & $password is an API token, and $subdomain is for my sponsored test account d3v-xxx
but it keeps failing with 404 Route not found
i'm trying to follow along with this guide: https://developer.zendesk.com/documentation/integration-services/zis-tutorials/zendesk-app-admin-interface/app-oauth/#register-the-integration
but can't continue due to the above error. i've already enabled the Zendesk API - what else am i missing?
