Hi @forbzie22_0253 ,
For the Native API, you would pass in a base-64 encoded string value for byte[] values. Sorry that we don't have any examples; it's not a very friendly API, and we don't call it via JSON ourselves. Most users will configure LDAP or SAML, so so this isn't a big priority for us to document or create an API for as you can understand.
If you find something that works, please do share it here :)
Thanks,
Alana
