Correct - VBA doesn't have a base64url encoder/decoder as standard. In fact, VBA doesn't have much as standard (because it is a programming language rather than a framework like .Net).
VBA-Web doesn't have one either at the moment either - but obviously there is nothing to stop anyone from adding one. I don't this will be difficult - as essentially you only need to translate certain characters to/from standard base64 encoding and VBA-Web already has Base64 encode / decode functions in WebHelpers.bas.
A description and some VB.Net code can be found here - and using this VB.Net code as a basis for adding Base64UrlEncode and Base64UrlDecode functions as wrappers to Base64Encode and Base64Decode functions should not be difficult (and would be a useful addition to VBA-Web).
