Salesforce to Jira Callout Failed ! Edited

[Hitesh Paarth]

When ever trying to hit the Jira Api's

Getting below response:

JSON Response: {"errorMessages":["Issue does not exist or you do not have permission to see it."],"errors":{}}

Moreover When i directly try to hit the endpoint URL , It works for me.

I have admin access for my user and still getting this error.

Below is the code snippet 

public string username ='XXXXXX';
public string password ='XXXXXXXXX';
HTTP h = new HTTP();
HTTPRequest r = new HTTPRequest();
r.setEndpoint('https://wuservicecloud.atlassian.net/rest/api/latest/issue/38281');

System.debug('User name'+username );
System.debug('Password'+password);
Blob headerValue = Blob.valueOf(username+':'+password);
String authorizationHeader = 'BASIC ' + EncodingUtil.base64Encode(headerValue);
r.setHeader('Authorization', authorizationHeader);
r.setHeader('Content-Type','application/json');
r.setMethod('GET');
System.debug('authorizationHeader ---->'+authorizationHeader );
HTTPResponse res = h.send(r);
System.debug('JSON Response: ' + res.getBody());

Kindly assist

Looks like the user you are using does not have access to that project (remember, Admin rights mean Admin, not "arbitrarily access everything").  Or it doesn't exist.
