how to Get token from URL?

My ADB2C created login page redirects to SPA after successful authentication and has an access token as URL parameter in the redirect URL. First, I want to extract an access token from a URL. Is this possible? And second, I want to store the extracted access token in localstorage. Is this also possible? Once these two are in place, I would expect the SPA to be able to access the backend API using an access token. thank you.

To get access token from URL make use of Postman.

• In Postman, Open & switch to Authorization tab
• Select OAuth 2.0 from the Type dropdown
• In Grant type dropdown, select Authorization Code
• In callback Url, enter your redirect Url
• In Auth Url, enter your Authorize Url
• In Access toke Url, enter your token Url
• Enter your client ID and enter scope.
• click the Get New Access Token button.
• And this will generate access token.
