Get value from url encodede response

[3DRaven]

Hi! Can I get value from url encoded response as parameter in json of next request? As example:
Twitter authentication OAuth 1.0a method

First request->status code = 200 OK and response body = "oauth_token=XXXXX&oauth_token_secret=XXXXX&user_id=XXXXXXX&screen_name=XXXXXX"

Second request-> need create body for another service, body=
{
"access_token"="here oauth_token=XXXXX from Twitter response"
}

How can I do it?
