I use the Buckets function in Oracle Cloud and I would like to know if there is any way to send an email/sms notifying when a user uploads files to the bucket.
I studied the documentation and found only bucket creation warnings.
Did you tried the Emit Object Events
on OCI bucket.
You can check out this doc for ref : https://www.jmjcloud.com/blog/oracle-cloud-infrastructure-events-with-apex-and-ords
You can check the object even types here : https://docs.oracle.com/en-us/iaas/Content/Events/Reference/eventsproducers.htm#ObjectStor__object
Create object event : com.oraclecloud.objectstorage.createobject
When the user uploads the file object is getting created in the bucket so you can use this event in the notification.
