Start and expiration dates need to be provided in compliance with the ISO 8601 norms. For example, 2020-03-11T09:00:00.000Z.
Custom code attributes (not supported by-default) need to be added as code metadata.
You cannot import the same codes to a single Voucherify Project.
In the structure representing your data, you can define a category that the voucher belongs to. You can later use the category of a voucher to group and search by specific criteria in the Dashboard and using the List Vouchers endpoint.
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.
