Please Help! Got error 400 when trying to add watcher using REST API.

[Johanes_Sungarda]

Dear all,

I'm trying to add 'watcher' support from our iPhone app that access JIRA using REST API.

I try to invoke "/rest/api/2/issue/<key>/watchers" and always get "400 bad request" error message! I use http method "POST" with data containing user name requesting to watch. In JIRA REST API doc, it say:

acceptable request representations:

• application/json<abbr title="{http://research.sun.com/wadl/2006/10} "></abbr> [collapse]
  <h6>Example</h6>

  "fred"

I try to send only "fred" string, json array "fred", dictionary "name=fred", but NOTHING works!

DELETE request works perfectly.

Please help as we want to release update for our iPhone app ("Resolveit for JIRA") as soon as possible.

Best regards,

Joe

Try sending the data with double quotes. Not just "fred" string but "\"fred\"". The following curl worked for me:

curl -i -u admin:admin -H "Content-Type: application/json" -H "Accept: application/json" -X POST -d '"jobinkk"' http://localhost:8080/rest/api/2/issue/TEST-1/watchers

Hi Jobin, That works perfectly :). Thanks a lot.

curl -D- -u admin:admin -X POST --data @C:\Users\folder\Desktop\testRest.json -H "Content-Type: application/json" http://jirainstanceon8w7:2990/rest/api/2/issue

what is wrong with my command ? Am i missing some parameter in it to create an issue

Hi  I am using postman to test this REST command I have tried with  quotes, without quotes, with keys but nothing seems to work.

Hope this helps someone as it was painful to determine what works

curl -i -u admin:admin -H "Content-Type: application/json" -H "Accept: application/json" -X POST -d """jobinkk""" http://localhost:8080/rest/api/2/issue/TEST-1/watchers

Does anyone know if it's possible to add a list of names to the watchers list in a single call, or would it have to be a separate call for each user to be added? (I tried a couple of different ways of passing in a list of names to the API, but it only ever took the first name).

This is bug since very long in JIRA .

I tried to add a watcher to one JIRA issue, but anyway,  it returns "bad request".

I can update assignee, comment, labels, .... with the similar code below, only watcher got me.

Thanks in advance.

my code is as below:

public void updateJiraWatcher(string key,string watcherName)

 

var request = new RestRequest()

{

Method=Method.Post,

Resource = "/rest/api/2/issue/"+key+"/watchers",

RequestFormat= DatFormat.JSon

};

string jsonWatcher ="{\""+watcherName+"\"}";  // "{\"username\":\""+watcherName +"\"}; ** doesn't work too

request.AddParameter("application/json",jsonWatcher,ParameterType.RequestBody);

var response = GetRequestsResponse(request);

Hello

I have the same problem, always got a bad request ,statuscode :400,

the above answers don't help,

my code below:

request.AddParameter("application/json",jsonWatcher,ParameterType.RequestBody);

var response = GetRequestsResponse(request);

I found that the parameter variable needed the quotes. Code solution below:

....

public void add_jira_Watcher(String issue_ID, String watcher) {

try {

.....

ClientResponse response = webResource.header("Authorization", "Basic " + auth_base_64).type("application/json").accept("application/json").post(ClientResponse.class, "\""+watcher+"\"");

.......

}

.....

Hope this helps anyone.

Hello,

I am also getting a 400 error. I'm doing this with java and am curiuos if anyone got the json syntax to work with the JRest APIs via Jersey classes?

ex)

//**************************************************************

// Add watcher to an existing JIRA issue

//**************************************************************

public void add_jira_Watcher(String issue_ID, String watcher) {

try {

String ji_rest_edit_URL = "http://"+ji_Host+"/rest/api/2/issue/"+issue_ID+"/watchers";

final String json_add_Watcher = "{\"username\": \"+watcher+\"}";

System.out.println("URL: " + ji_rest_edit_URL);

WebResource webResource = client.resource(ji_rest_edit_URL);

ClientResponse response = webResource.header("Authorization", "Basic " + auth_base_64).type("application/json").accept("application/json").post(ClientResponse.class, json_add_Watcher);

@SuppressWarnings("deprecation")

int statusCode = response.getResponseStatus().getStatusCode();

if (statusCode != 204) {

jrest_API_Logger.info("add_jira_Watcher() --> Watcher added failed to issue "+issue_ID+": "+statusCode);

} else {

System.out.println("wachter: " + watcher + " was added to jira issue: "+issue_ID+": "+statusCode);

}

} catch (ClientHandlerException ex) {

jrest_API_Logger.info("add_jira_Watcher() ClientHandlerException ex.getMessage(): " + ex.getMessage() + ": " + issue_ID);

} catch (Exception ex) {

jrest_API_Logger.info("add_jira_Watcher() Exception ex.getMessage(): " + ex.getMessage() + ": " + issue_ID);

}

}

Thanks in advance.

Just my $0.02 here for someone who is using .NET to post. Make sure you enclose your string between quotes:

string.Format("\"{0}\"",userName)

Otherwise it was failing in my env since we are using firstname.lastname for the usernames and that period in the middle was the issue.

Use JSONObject.quote function pass a string. This worked for me in REST API

Is this still valid? I'm getting the 400/Bad Request error using

a _curlrc file with

-H "Content-Type: application/json"

-k

-u username:password

--silent

--show-error

and a command line of

./curl -i -H "Accept: application/json" -X POST -d '"username"' https://hostname.jira.com/rest/api/latest/issue/ISSUE-id/watchers

"The request sent by the client was syntactically incorrect (Bad Request)"
