If you can't see the option to create Unique auto generated coupon pools in the coupon pools screen and you are a Shopify user, follow these steps.
If you are not a Shopify user, please raise a support request.
First go to your Shopify account and uninstall the Ometria app.
Next, reinstall the app.
See: Uninstalling an app (Shopify help centre)
After you've reinstalled, contact your Customer Success Representative, who can update your account's permanent access token for you in the Ometria back end.
Once that's done you'll have the right access settings to create unique auto generated coupon pools in Ometria.
Checking access scopes
You can check whether or not you have access to create these coupon pools by calling Shopify's API.
See Shopify's documentation: Get a list of access scopes
Use the API URL:
https://stor_url/admin/oauth/access_scopes.json and pass the access token through the header, e.g.
Next, execute this command:
curl -X GET "https://stor_url/admin/oauth/access_scopes.json" \
> -H "X-Shopify-Access-Token: access_token"
