We need to upload files of more than 1 Gb size. Is the IBC Loader that can be downloaded from GitHub recommended by Celonis?Is there any other way to upload big files?Thanks

You can use Celonis' Data Push API (pushing data via HTTP) or the pycelonis Python library which is easier to handle.

Link: Pycelonis documentation

For the doku of the Data Push API just search in the Celonis Help for "Data Push API".

Thanks
