How do I log work for a user via the Jira Cloud REST API?

I'm trying to use the REST api in a laravel app, to add worklogs to an issue on my company's Jira Cloud instance.

Whenever I sent the request it gives me an error, "Can not instantiate value of type [simple type, class] from JSON String; no single-String constructor/factory method"

I'm sending the post request to with this JSON:

                "comment":"Testing pushing worklog using REST API",

I've also tried sending just:

"comment":"Testing pushing worklog using REST API",

Can anyone spot what I'm doing wrong?

Hi Benjamin,

Here is the example from the Cloud API documentation for updating a worklog:

    "comment": "I did some work here.",
    "visibility": {
        "type": "group",
        "value": "jira-developers"
    "started": "2017-08-15T06:53:06.605+0000",
    "timeSpentSeconds": 12000

The format you would use for the call is

Try that format and see if you get different results.



Thanks for your answer, but how would I give the worklog ID if I'm trying to create a worklog that doesn't exist yet, not update an existing one?
