original works in php 5.4:

$coupon->store_discount_reference = ['und'=>[['target_id'=>"57"]]]; $coupon->store_coupon_exclusive = ['und'=>[['value'=>"0"]]]; $coupon->store_coupon_conditions = ['und' => [     [         'condition_name'=>'store_coupon_usage_evaluate_usage',         'condition_settings'=> ['max_usage'=>'1'],         'conditions_negative'=>0,         'remove_condition'=>'remove'     ], ]]; 

what have tried

$coupon->store_discount_reference = array('und'=> array('target_id'=>"57")); $coupon->store_coupon_exclusive = array('und'=> array('value'=>"0")); $coupon->store_coupon_conditions = array('und' => array('condition_name'=>'store_coupon_usage_evaluate_usage','condition_settings'=> array('max_usage'=>'1'),'conditions_negative'=>0,'remove_condition'=>'remove')); 

full chunk

$coupon = new stdclass(); $coupon->type = "discount_coupon"; $coupon->coupon_id = ''; $coupon->code = $code; $coupon->bulk = false; $coupon->created = ''; $coupon->status = 1; $coupon->uid = 0; $coupon->is_new = true; $coupon->commerce_discount_reference = ['und'=>[['target_id'=>"57"]]]; $coupon->commerce_coupon_exclusive = ['und'=>[['value'=>"0"]]]; $coupon->commerce_coupon_conditions = ['und' => [     [         'condition_name'=>'commerce_coupon_usage_evaluate_usage',         'condition_settings'=> ['max_usage'=>'1'],         'conditions_negative'=>0,         'remove_condition'=>'remove'     ], ]]; commerce_coupon_save($coupon); 

you appear missing array level everywhere

$coupon->store_discount_reference = array('und'=> array(array('target_id'=>"57")));  $coupon->store_coupon_exclusive = array('und'=> array( array('value'=>"0")));  $coupon->store_coupon_conditions =     array('und' =>             array(                    array('condition_name'=>'store_coupon_usage_evaluate_usage',                         'condition_settings'=> array('max_usage'=>'1'),                         'conditions_negative'=>0,                         'remove_condition'=>'remove'                    )                 )   );
