I just can't figure out how to enable Content Delivery API in V15 Clean install (Umbraco.Templates::15.0.0-rc1) Enable Delivery Api in appsettings.json Go to /umbraco/swagger, I can only see Umbraco Management API Any ideas?

Is AddDeliveryApi() been called on startup?

No, that's it. Thank You! It probably should be mentioned in the docs https://docs.umbraco.com/umbraco-cms/reference/content-delivery-api

That is the V14 docs -- it will be documented in the V15 docs, which is still being written. You can follow along here on what has already been published for V15: https://docs.umbraco.com/umbraco-cms/15.latest-rc
