Hi @abhijithr ,
Yes, there is documentation on how to use SFTP for Adobe Analytics instead of HTTP via the Bulk Insertion API.
Using SFTP can be more suitable for handling larger files securely.
You can find the detailed instructions in the Adobe Secure File Transfer Protocol documentation(https://experienceleague.adobe.com/en/docs/analytics/export/ftp-and-sftp/secure-file-transfer-protoc...). This resource provides information on setting up an SFTP account and transferring data files securely.
Hope this helps!
