How can you store some data during the authentication in an object so that I can access that field in a stream?

You can store data during the authentication in an object by defining a new class that inherits from an existing authenticator class. This new class can include methods to store and retrieve data as needed. For example, in the case of the Webflow API, a new class called

WebflowTokenAuthenticator

is defined, which inherits from the

TokenAuthenticator

class. This class uses a mixin called

WebflowAuthMixin

to override the default

get_auth_header

method so that

accept-version

will be included in the header. The

WebflowTokenAuthenticator

class is instantiated as an object called

auth

as follows:

python auth = WebflowTokenAuthenticator(token=api_key, accept_version=accept_version)

The

auth

object created by this call is passed to each stream, and ensures that

accept-version

will be included in each API request. This way, the

accept-version

data is stored in the

auth

object and can be accessed in each stream. You can follow a similar approach to store and access data in your own authenticator class. Just make sure to pass the object to each stream where you need to access the data. For more details, you can refer to the [Webflow API tutorial](https://airbyte.com/tutorials/extract-data-from-the-webflow-api#step-2) on the Airbyte website.
