Hello guys,

I am new to Umbraco and dealing with a little challenge.

I added a Umbraco.Tags editor to a document type what works really cool!

Now I want to validate a given code (tag) (on-the-fly) as soon as I press enter, it has to call a (surface/umbracoJson) controller what will call a external API, the result (a string) should be added to the 'Validation result' (by more results as a comma separated value) When a tag is deleted, the result should update as well.

See my idea in the image below:

Is this possible, so yes.. How? Should I create a custom data type or property editor?

Can someone give me a little bit advice?

Thank you so much in advance, have a good day!
