Hi @Dhilip Subramanian ,
Thank you for posting query in Microsoft Q&A Platform.
Are you using REST connector dataset inside Copy activity, Source Tab? Is your API call inside Copy activity, source tab downloads file? If yes, Kindly use HTTP connector type dataset as source dataset inside copy activity and see how it goes.
Please let me know how it goes. Please feel free to share screenshots of complete implementation that helps to repro and understand root cause better. Thank you.
