How to decode HTTP request query string in azure APIM policies?

I have URL in the below format, and I want to decode the query string and re-write the URL.

https://api.test.abc.com/parameters?username=%7Busername%7D

How can I decode username using policies and re-write it in the following format:

API Endpoint: /api/affiliated/users/userInfo/?username=abcd.gmail.com

Many thanks in advance.

We cannot directly decode, as there is no option, we have to do delete the first query parameter and rewrite the URI by changing and decoding the query parameter. I used the below code snippet to execute that. (as the question was also to replace the userName in the URL with visibleToUserId along with decoding the value.)

@((Convert.ToBase64String(Encoding.UTF8.GetBytes((string)context.Request.MatchedParameters[\"visibleToUserId\"]))).Replace('=', '~').Replace('+', '-').Replace('/', '_'))

You can decode it manually.

context.Request.Url.Query["username"] | Replace:'%7B','{' | Replace:'%7D','}'

Save that username in one variable and use it in rewrite template.

I too want to know some method to decode url in APIM policy.
