Is there a way to remove Base64 data from the API response?

Yes, but this setting is not configurable in the API request. Clients need to contact support@rchilli.com to request disabling Base64 data, file name, and sub-user ID in the email inbox integration response.

If you still have any questions, you can always contact RChilli Support by creating an RChilli Helpdesk ticket or sending an email at support@rchilli.com.
