The Stack Exchange API is mostly based on 'ids'. IE
/2.2/users/{ids}/top-tags?site=stackoverflow
How can we get {ids} for a particular user using his email id or name? Is there any method available to get details about a particular user in stack exchange?
No. You cannot search for a user by email address. Email accounts are sensitive private information and not disclosed by Stack Exchange.
You can search for users by display-name though. See the documentation for /users. You can use the inname parameter.
For example:
/2.2/users?order=desc&sort=reputation&inname=Stack&site=stackoverflow
Returns all the users on Stack Overflow that have stack (case insensitive) in their display name.
