This method gives the possibility to push new vouchers to an existing campaign. New vouchers will inherit properties from the campaign profile. However, it is possible to overwrite some of them in the request body. If you provide an optional code_config parameter with a voucher code configuration, then it will be used to generate new voucher codes. Otherwise, the voucher code configuration from the campaign will be used.
This API request starts a process that affects Voucherify data in bulk.
In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.
The result will return the async ID. You can verify the status of your request via this API request.
