For on-going synchronization, the [create order](ref:create-order) and [update order](ref:update-order) endpoints should be used. This is critical because this endpoint does not store events or launch distributions. ## Limitations ### Import volume There can be only a single on-going order import per tenant per project at a given time. The user can schedule more imports but those extra imports will be scheduled to run in sequence one by one. ### Maximum count of orders in single import There is a `2000` limit but we might decide to change it to a lower / higher value at any given time depending if we find this value is too high or too low with time. ## Notifications There are no notifications on the Dashboard because this import is launched via the API. ## Triggered actions If you import orders with customers, then a logic will be scheduled responsible for placing these customers into segments and refreshing the segment's summary. Consequently, this update will trigger - **customers entering into segments** - **distributions** based on any rules tied to customer entering segment(s) - **earning rules** based on the customer entering segment(s) ## What is not triggered 1. No webhooks are triggered during the import of orders - for both orders and upserted products / skus. 2. Distributions based on Order Update, Order Paid, Order Created and Order Cancelled. In other words if you have a distribution based on Order Paid and you import an order with a PAID status, the distribution is not going to be triggered. 3. No events are created during the import of orders - for both orders and upserted products / skus. In other words you won't see any events in the Activity tab in the Dashboard such as Order created or Order paid. If you are additionally upserting products / skus, then you won't see the Product created events listed, etc. 4. Earning rules based on Order Paid won't be triggered. 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](ref:get-async-action).
