Need help in parsing the below using reex

Question

I am zero in regex and need help in parsing the value for key "access_token" from the below output.This will be later used in passing as variable for another function. So basically the regex should only fetch

[As with HTML](https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags#1732454), you can't use a single regular expression to parse JSON. As with HTML, you'll be tricked into thinking "Oh, but this is a simple, contained use case..." Don't be. :-) Use a parser. If you'd told us what environment you want to do this in (JavaScript, Java, PHP, C#, Ruby, ...) we could have pointed you at how you parse JSON in that environment. — T.J.

Using regex? I suppose you should be using a better library that's designed specifically for JSON. — iBug, Oct 07 '18 at 12:42

Simple PCRE look like

\"access_token\":.\"(.+?)\"

And you will get your token in fast captured group You can practice with this regex on this website https://regex101.com/
