For the Snowflake element, Cloud Elements provides native bulk as an option to upload / download large number of resources, such as contacts, into a cloud service all at once. The Bulk APIs require the name of the object identified within the cloud service and a .csv or a .json file with populated data included in each request. Cloud Elements provides discovery services to get a list of available objects.
If you configured the Callback Notification Signature Key (
event.notification.signature.key) when you authenticated an element instance, the bulk APIs will use the signature key to provide hash verification in the header of bulk jobs. For more information, see Hash Verification.
