Hi how do I from code perform a URL check to check that a url is not in use / get an alternative url suggestion if it is in use? (I am dynamically creating pages and categorys)

Litium version: 7

I think you can use UrlHelper for that cause.

Any updates/examples to this?  
I would like to check if a category already exists with the URL I’m trying to create dynamically with CategoryService.

Inject ISuggetionService and then use Suggest method.

Tried that but gives me the following error:  
“Localization[sv-SE].Url: ‘The URL is occupied by a sibling category.’.”

Seems like it only suggests an url, not checking if there’s already an existing category with that suggestion.

It has to give you a non existing url otherwise it might be a bug.

`ISuggetionService` is **not** validating that the url-segment is in use, it is suggesting an sanitized url-segment. To be able to validate if the url-segment can be used also other parameters need to be included like if the url is for a page, category, base product or variant and if it is a page or category it also need to know the parent object.

If you only want to do a validation before saving you can inject the `ValidationService` and use the validate method on that to get an answer if the entity have any invalid data, it is this method that the create/update methods are using.
