How to fetch JIRA tickets using REST API in Salesforce Apex

[ExcitedGamer85]

I’m working on connecting to JIRA from Salesforce and need to execute JQL queries through their REST API. My current implementation isn’t working properly and I keep getting format errors.

Here’s what I have so far:

public class AtlassianClient {
    private static final String BASE_ENDPOINT = 'https://mycompany.atlassian.net';
    private static final String AUTH_TOKEN = 'my_token_here';
    
    public static HttpResponse fetchTickets(String queryString) {
        HttpRequest req = new HttpRequest();
        req.setEndpoint(BASE_ENDPOINT + '/rest/api/3/search');
        req.setMethod('POST');
        req.setHeader('Authorization', 'Basic ' + EncodingUtil.base64Encode(Blob.valueOf('apiToken:' + AUTH_TOKEN)));
        req.setHeader('Accept', 'application/json');
        
        Map<String, Object> bodyData = new Map<String, Object>{
            'jql' => queryString
        };
        String jsonBody = JSON.serialize(bodyData);
        req.setBody(jsonBody);
        
        System.debug(jsonBody);
        return new Http().send(req);
    }
}

I’m testing it like this:

HttpResponse result = AtlassianClient.fetchTickets('project = "TEST"');
if (result.getStatusCode() == 415) {
    String body = result.getBody();
    System.debug('Error Response: ' + body);
    
    List<String> headers = result.getHeaderKeys();
    for (String headerName : headers) {
        System.debug('Header: ' + headerName);
    }
} else {
    String body = result.getBody();
    System.debug('Success Response: ' + body);
}

The response keeps telling me the body format is unsupported. What am I doing wrong with the request structure?

Your Basic auth format is wrong. JIRA API tokens need email:token, not apiToken:token. Change your authorization header to req.setHeader('Authorization', 'Basic ' + EncodingUtil.base64Encode(Blob.valueOf('[email protected]:' + AUTH_TOKEN)));. And double-check you’re using an actual API token from JIRA account settings, not your password. Had the exact same problem when I first set up JIRA with Salesforce - this fixed it. That 415 error is misleading when it’s really an auth issue.

you probly need to add the content-type header. jira’s api is super picky. try adding req.setHeader('Content-Type', 'application/json'); right before sending your request. that usually fixes those 415 errors even if your json seems alright.

The problem’s with your endpoint and request method. You’re using POST to /rest/api/3/search, but JIRA’s search endpoint works better with GET requests where you pass the JQL as a URL parameter.

Try switching to GET and append the JQL as a query parameter: req.setEndpoint(BASE_ENDPOINT + '/rest/api/3/search?jql=' + EncodingUtil.urlEncode(queryString, 'UTF-8')); Then ditch the body completely.

I’ve hit this exact issue before - the API expects GET for search operations even though POST sometimes works. That 415 error usually pops up when you send a body with GET or when the endpoint wants parameters instead of JSON payload.
