Input information example
Make sure to set your Logon Type to the preferred authentication type with either a username/password or a user and key file path.
Transferring Files
After configuring the connection, you may navigate the folder structure to find the files you wish to transfer.
The folder structure is arranged like so:
/Data Category/Dataset/Year/Month/Day/Files
An example of a directory path can be:
/TERM_SOFR/TERM_SOFR_DAILY/2025/01/23/SOFRT_TermRate_Fixings_20250123.CSV
You have the option to navigate to the exact file to download it or to download a batch of files from a given directory. Note that you can only view and transfer historic data you have already purchased based on the entitlements associated with your API key.
