Update several customers metadata properties in one asynchronous operation.
In one request, it is possible to update a maximum of 100 records. In the response body, you get a unique async action identifier.
If a requested customer object is not found, then an upsert occurs. This is reflected in the Get Async Action endpoint as follows:
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.
