How to get userid by email using API?

[Christoph Roth]

Hello,

I am developing an Application that creates Issues in Jira, and I need to get the username of the current user by email. 

I already found this. When I open this query in my browser, for example:

https://jira.mycompany.de/rest/api/2/user/search?username=email@mycompany.de

this works fine, but only while I am logged in in Jira. 

However, 

when I try to use this in my code, it returns no result.

var url = "https://jira.mycompany.de/rest/api/2/user/search?username=" + email;
var result = new WebClient().DownloadString(url);

I know that this resource cant be accessed anonymously, as stated in the documentation.

How can I do this programmatically?

You would need to pass the Authorizaiton header to your request. You can read more here:

Go to the Supplying basic auth headers part.

Could you show me an example on how to use this in C#?

Sorry, I am a Java developer :)

Nevermind, I was able to figure it out myself :)

 Here is what I did, in case anyone might need it in the Future. 

 var url = "https://jira.mycompany.de/rest/api/2/user/search?username=" + email;

 string header = "Username:Password";
 
 string encoded = Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes(header));

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
 request.Headers.Add("Authorization", "Basic " + encoded);
 request.PreAuthenticate = true;

 HttpWebResponse response = (HttpWebResponse)request.GetResponse();

 using (Stream stream = response.GetResponseStream())
 {
  StreamReader reader = new StreamReader(stream, Encoding.UTF8);
  var result = reader.ReadToEnd();
 }

Thank you for your assistance :)

Finally working. Thanks

This solution no longer works: 

{"errorMessages":["The query parameter 'username' is not supported in GDPR strict mode."],"errors":{}}

This should work :
