I am using asana php api and all working fine. But now i want to submit custom field value. I have created custom field in particular asana project. But when I am trying to submit through API, it is not submitting. I am not sure what should pass as parameter in php API. Below is custom field ids:

// documentos - 227624521239196  
// Amortização - 320114643060735

And below is my api code:

$custField = array(“documentos” =\> “Amortização”);

$result = $asana-\>createTask(array(  
‘workspace’ =\> ‘xxxxxxxxxx’,  
‘custom\_fields’ =\> $custField,   
‘name’ =\> ‘xxxxxx’,  
‘notes’ =\> ‘xxxxx’,  
‘tags’ =\> ‘xxxxxx’,  
‘due\_on’ =\> ‘xxxxxx’,  
‘assignee’ =\> ‘xxxxxxx’,  
‘followers’ =\> ‘xxxxxx’  
));

Hi,

The structure of your `custom_fields` is wrong, you need to pass couples of id-value.
