Help with GraphQL syntax through the API Playground interface

Is it possible to use variables in GraphQL syntax for column values in a mutation? In the example below, I am can use a variable for top level items like board_id and item name. I can’t embed a variable inside column_values for date and the url. I am doing this to allow someone on my team the bulk assign training assignments through the API Playground tool instead of running a Python script I created.

Thanks
Bruce

Example 1
mutation addTraining($myBoardID: Int!, $myItemName: String) {
bruceB: create_item(
board_id: $myBoardID,
item_name: $myItemName,
column_values:
“{
"status": {"label": "New"},
"status_11": {"label": "HP Mandatory Training"},
"link" : "www.test.com Title Here",
"date4" : {"date" : "2023-05-31"},
"person": {"personsAndTeams" :[ {"id" : 11111111, "kind" : "person"}]}
}”
) {
id
}

  cindi: create_item(
board_id: $myBoardID, 
item_name: $myItemName,
column_values:
"{
\"status\": {\"label\": \"New\"},
\"status_11\": {\"label\": \"HP Mandatory Training\"},
\"link\" : \"www.test.com Title Here\",
\"date4\" : {\"date\" : \"2023-05-31\"},
\"person\": {\"personsAndTeams\" :[ {\"id\" : 22222222, \"kind\" : \"person\"}]}  
}"

) {
id
}

Variables
{
“myBoardID”: ########,
“myItemName”: “Test Training”
}

Hello there @BruceB,

You can not pass a variable into the column values from the Playground.

Let me know if you have any other questions :slightly_smiling_face:
