Hi everyone

I have been asked to send events to some contacts timeline automatically using a scheduled script.

It seems the oauth2 needs the user to use his browser to authenticate (and get the code)

Given I would need to authenticate within the script,  
does it exist another way ? For example using the api key ?

The documentation does not mention it.

Hi @Jim

Oauth requires a HubSpot user to log in and click the grant access button, after which you’d get a code that can be used to get the access token and refresh token. If you provide the refresh token to your script, it would be able to get access\_tokens to access the APIs going forward.

Does this refresh\_token expire? Can I store it and use for all further calls to the api?

Hi [@Sebastian\_Lozada](https://community.hubspot.com/u/sebastian_lozada) and [@yogen](https://community.hubspot.com/u/yogen),

The `refresh_token` does _not_ expire, so you can store it and use it to obtain a new `access_token` every 6 hours, per [this documentation](https://developers.hubspot.com/docs/methods/oauth2/refresh-access-token).
