I am trying to hit API from C# code using HTTP client but I am getting the result as unauthorized. If I try with postman it's working fine. what will the issue ?

Hi Vamsi

My C# application has the following 2 lines before the Convert.ToBase64String :

string mergedCredentials = string.Format("{0}:{1}", m_Username, m_Password);
byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
return Convert.ToBase64String(byteCredentials);

Try to see if that helps

Thanks Warren for responding.

I am getting the AuthCredentials in the perfect way. I think it's problem with the permissions. Do we need to enable any permission ?

Hi Vamsi

If I'm correct, the call you're doing (https://hrbotdev.atlassian.net/rest/api/latest/issue) isn't valid, because it needs a further /ABC-123 passing in the issue key.

I tried your call but with my Jira name instead of hrbotdev and I received an error. I added a key and it worked, so I think you need

https://hrbotdev.atlassian.net/rest/api/latest/issue/ABC-1234

[Vamsi]

Yeah, that is for getting the issue which has been already created. I want create the issue using the API.

Hello,

It mean you provide invalid credentials or you do not provide credentials at all.

[Vamsi]

No, I am giving the creadentials.

string authCredentials = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(Username + ":" + Password));
client.DefaultRequestHeaders.Add("Authorization", "Basic " + authCredentials);
client.DefaultRequestHeaders.Add("Accept", "application/json");
var result = JsonConvert.SerializeObject(model);
var response = await client.PostAsync($"https://hrbotdev.atlassian.net/rest/api/latest/issue", new StringContent(result, Encoding.UTF8, "application/json"));

Could you somehow to see, what request is sent from your program? I usually use Fiddler for it.

[Vamsi]

It's working in postman fine. In program only it's not working

[Alexey Matveev]

It means that your request, which is sent from your program, is different from postman. You need to see your request.

[Vamsi]

No, both are same. The following is the API

https://hrbotdev.atlassian.net/rest/api/latest/issue

[Alexey Matveev]

If they were same, then the result would be also same 

[Vamsi]

I tried with all those, I think it's not problem from coding side. Because when I tried the same request in others system postman, they also got Unauthorized status code. It means when we access it remotely It's not working. Do I need to enable any permission to access it globally in atlassian account ?

[Alexey Matveev]

No, there is no permissions like this. You said before, that it worked in postman and now it does not work. What is the difference?

[Vamsi]

It worked in my system(i.e., in postman). In others system postman request also not working.
