JIRA REST API "The username query parameter was not provided" even though the parameter is provided.

[Eric Adlard]

When using the "rest/api/2/user/search" endpoint and passing the "username" parameter, I get the following message returned from the API.

{    "errorMessages": [        "The username query parameter was not provided"    ],    "errors": {}}

I'm currently using Postman, and attached is my GET request with my body content (as you can see, "username" is provided). I'm using basic authentication via an admin account, and I can manually search for users within the JIRA GUI, so I don't think there is a permissions issue.

I've also tried using the "rest/api/2/user" endpoint with both the "username" and "accountId" query parameters, but get a similar message.

{    "errorMessages": [        "Either the 'username' or the 'key' query parameters need to be provided"    ],    "errors": {}}

Any help you can provided would be appreciated.

Thank you.

Hi @Eric Adlard 

When you are using GET method to search issues via jql you don't need use body.

Take a look at this example: https://developer.atlassian.com/server/jira/platform/jira-rest-api-examples/#searching-for-issues-examples

Hi @Sebastian Krzewiński 

Thanks for your reply - it pointed me in the right direction and I was able to resolve my issue by putting the parameters in the URL path of the GET request.

https://my.url/rest/api/2/user?username=abc123

I was then able to get back either a 200 for when the user existed, or a 404 when the user did not exist. Success!

Thanks again!
