Ability to update multi-user picker over API (only additions)

Matus Klaudiny

Hello Team,

I struggle to find a right syntax for my Custom API Request. Goal is to update multiuser picker without removing current values of the field:

I can confirm that the "fields" method works for SET setting up the field.
____
{
"fields": {
"customfield_10003": [
{
"id": "XYZaccountId1"
},
{
"id": "XYZaccountId2"
},
{
"id": "XYZaccountId3"
}
]
}
}
___

However I want to add values without removal using update method. Which seems to not work, my current syntax for the body is:

{
"update": {
"customfield_10003": [
{
"add": "XYZaccountId1"
},
{
"add": "XYZaccountId2"
},
{
"add": "XYZaccountId3"
}
]
}
}
__

Would you like to help me find the right syntax for this to work?

After some testing I have found the correct syntax. 


{
"update": {
"customfield_10003": [
{
"add": {
"id": "XYZ1"
}
},
{
"add": {
"id": "XYZ2"
}
},
{
"add": {
"id": "XYZ3"
}
}
]
}
}
