Adding a user to a custom field (user field) using JIRA API

[Tom Dangot]

Hey, i've got an automation that creates a jira issue using python. One of my custom fields is user field. I've tried multiple options but none of them seems to be working an actually add a user to this field.

I've tried: 

"customfield_10492": {"name":"tom.dangot"}

"customfield_10492": {"value":"tom.dangot"}

"customfield_10492": {"name":"tom dangot"}

"customfield_10492": {"name":"my account id"}

"customfield_10492": {"value":"my account id"}

"customfield_10492": {"value":"[~accountid:my account id]"}



None of them worked, would appreciate your help

The format is like this:

{
  "fields": {
    "customfield_10003": [{
      "accountId": "444444-2ccc-4bbb-8888-8888888888"
    }]
  }
}
