We have been tasked with being able to call Web Services such as Graph API and others where we need to send Base64 Strings into the POST data for things like Email Attachments where the customers require their own domain to be used.

We can only achieve this currently by utilizing a remote SDK Script to export the document on a local server and converting to its Base64 and sending back as an output token.  This is only useful if the customer is happy to have a hybrid of On prem and Cloud though.

Maybe a token calculator method attached to starting entry could be used to return the Base64 easily and quickly.

Thanks
