I am working in wordpress edd plugin, in which i have requirement of create edd coupon code dynamically with specific amount, start date, end date and assign user to that code. I have not found any filter/action hook that will accomplish this task. Any help should useful to me.

EDD provides edd_store_discount() function to add discount code programatically. You need to pass details as an array. Please check following example. In the following example, discount code festival50 is created dynamically. This example discount code allows 50% discount. You can take following example and add other relevant parameters for the discount code.

$details = array(
    'name' => 'Festival',
    'code' => 'festival50',
    'type' => 'percent',
    'amount' => 50,
);

edd_store_discount( $details );
