event.acknowledge: No permissions to referred object or it does not exist!

[Towermoni]

I'm creating a script to acknowledge a trigger and send a message to Zabbix's API. Below is my section that handles the data:

$data = json_encode([
'jsonrpc' => '2.0',
'method' => 'event.acknowledge',
'params' => [
"eventids" => $trigger_id, // ID of the event you want to acknowledge
"action" => 6,
"message" => $message // Custom message for acknowledgment
],
'auth' => $auth_token,
'id' => 1
]); 

I verified the trigger ID, API key, and the URL to be correct though when I run the php script I get:

{"code":-32500,"message":"Application error.","data":"No permissions to referred object or it does not exist!"} 

What should I modify to solve the issue? Does the trigger in question need to be triggered in order for me to acknowledge it? I've included a photo of the test trigger i'm attempting to acknowledge and send a message to:

Update: I found I was referencing the wrong ID (I.E I was referencing the 'triggerid' when I should have been referencing the 'eventid'. The script now works as intended
