Via Webflow Forms with Microservice

Hello, i was able to send login information via POST method to a microservice, and it returns a URL to get into a private portal for that website.

What i need to know is, how do I redirect to the provided URL? right now, I am directed to the .axd microservice, and the URL is in plain text on the new page.
