Not geeting sys_tags field value through Rest API Explorer

Not geeting sys_tags field value through Rest API Explorer, I have a incident record and sys_tags field have some value but when getting through Rest API explorer on "

instancename/api/now/table/label/7dc355982b6cb610ea3af1d4b891bff2"

7dc355982b6cb610ea3af1d4b891bff2":- sys_id of the record

{
  "result": {
    "sys_id": "7dc355982b6cb610ea3af1d4b891bff2",
    "name": "Shashank Test",
    "type": "standard",
    "sys_tags": "",
    "sys_class_name": "label"
  }
}
sys_tags = blank is coming

This happens because:

• sys_tags is a non-persistent (derived) field.

• The REST API serializer doesn’t include calculated fields unless explicitly added.

• So the REST API only returns physical fields stored in the DB.

If you want to retrieve the tags associated with a record (like an Incident), you need to query the label_entry table, which holds that relationship.

You can Query /api/now/table/label_entry?table=<table_name>^table_key=<sys_id>since, tags actually stored In the label_entry table, linked to the record via table + table_key.

/api/now/table/label_entry?table=<table_name>^table_key=<sys_id> -- what will be the table_name?
/api/now/table/label_entry?table=incident^table_key=e003d518fbe43a504e88f26165efdcb5 --Like this? sys_id is incident record sys_id?

@shashanksha yes, let's verify it carefully

@Nilesh Pol ,

Actually User is Adding the tag on incident form and than hitting the API from Post man to fetch the sys_tags field value, so i think it is not posible it will come like this directly. How can user fetch the sys_tag field which they enter on incident form to add.?
