Hi Shrinivas,
You can retrieve all the Objects from db, that are stored to excel import,
Now, Loop on them and Inside the loop you can create the microflow logic of sending the data through REST, and configure this microflow inside the loop to be executed in taskqueue.
THis way, you will be able to achieve it .
Hope it helps!
Yes you can. After the import you could just retrieve the first record do the REST call. Then set a boolean processed for this record and retrieve the next record that is not processed. Continue doing this untill there are no records left.
