Hi @saja-3124,

Authorization request header is used for specifying the OAuth token and token type used to authorize the request. When passing the OAuth token value, it's important to use "Bearer" as the prefix. This indicates that the token is a Bearer token, which is a common type used in OAuth 2.0 authentication.

Here's an example of how to format the Authorization header:

Authorization: Bearer v^1.1#i^1#p^3#I^3#r^0#f^0#t^H4sIAAAA
