How can i create a buy order for an unusual through API?

[Eqbits]

It should be a specific effect. I only could create a non-effect one so far with code like this:

'intent' => '0',
    'item' => array(
        'quality' => '5',
        'item_name' => $hat
    ),
    'details' => '...',
    'currencies' => array(
        'metal' => $buyMetal,
        'keys' => $buyKeys
    )

 

Search didn't help

Add priceindex after item_name with the effect's ID

Thanks a lot!
