Fetch token via authorization response URL at later point in time

[autochargetesla]

Hello!

Excellent work on this library !

As described in the section Alternative, the URL generated after successful Tesla login in the browser is (immediately) supplied to authorization_response. As a result, the tokens are generated and available to TeslaPy. This works perfectly !

In our use case, there will be a minor delay between these two steps. Therefore, the question is: is it possible to run TeslaPy to generate the tokens from the authorization_response URL independently from the first step?

To summarize this two-step use case:

1. Run TeslaPy to generate tesla.authorization_url(), paste URL in the browser and perform Tesla login resulting in 404 page. Copy this URL for later use.
2. Run TeslaPy (again) and supply the URL copied before as authorization_response (or elsewhere?) to generate set the of tokens (e.g. refresh token).

Cheers!

This is currently not possible. I have to change the return type of authorization_url() from a string to a tuple that contains the url and state string, as this is required for the two-step use case to work.

Thank you for the response. With url and state string you mean authorization_url and state correct? Simply restoring those values (as obtained as a result of step 1) by setting them in the tesla object does not seem to work (causes Unauthorized client).

It also requires code_verifier to be set. Then it works.

This should work:

import teslapy

tesla = teslapy.Tesla('elon@tesla.com')
if not tesla.authorized:
    print('Use browser to login. Page Not Found will be shown at success.')
    state = tesla.new_state()
    url = tesla.authorization_url(state=state)
    code_verifier = tesla.code_verifier
    print('Open this URL: ' + url)
tesla.close()
del tesla

tesla = teslapy.Tesla('elon@tesla.com', state=state)
if not tesla.authorized:
    tesla.fetch_token(authorization_response=input('Enter URL after authentication: '),
                      code_verifier=code_verifier)
vehicles = tesla.vehicle_list()
print(vehicles[0])
tesla.close()

Does this cover your use case?

Hi!

Thank you very much :-)

This is exactly what we needed!

Commit e88ec08 includes better support for staged authorization and an updated readme as well.
Happy Easter

Hello @tdorssers, thank you for your previous support on answering my questions!

I have a follow-up question:
Are you aware of any expiration date in the future of authorization_url or will it always be valid?

Cheers

[tdorssers]

It should always be valid
