Hi,

How can I integrate Timeline API into my project where any action made by user will create a timeline in background job?

I read that it requires OAuth token, but if my website is hosted then how much time OAuth token will be valid?

Does that means I need to login ONLY ONCE to obtain token after that from background I can refresh token?

Hi [@yogen](https://community.hubspot.com/u/yogen),

As outlined in [this article](https://developers.hubspot.com/docs/methods/oauth2/get-access-and-refresh-tokens), OAuth tokens expire after **6 hours**. You can then use the refresh token to get a new access token which will last another 6 hours. It is certainly possible to set up automation to repeatedly refresh your integration’s access token every 6 hours. The `refresh_token` you receive when initiating the OAuth connection does _not_ expire, so you can keep using it to refresh the `access_token`.

Do you have any other specific questions after reviewing the [Timeline API overview documentation](https://developers.hubspot.com/docs/methods/timeline/timeline-overview)? I also found [this similar topic](https://integrate.hubspot.com/t/keeping-oauth2-access-tokens-refreshed/3113) relating to authenticating the Timeline API.

[@Isaac\_Takushi](https://community.hubspot.com/u/isaac_takushi) Thanks for quick reply.

What I understood is, After hosting my app, I need to LOGIN Only once to get initial token and refresh token.

After that, I can use refresh\_token in background job to get updated token every time without being worried about expiration.

That’s correct, [@yogen](https://community.hubspot.com/u/yogen)! Once you get the `refresh_token`, you can use it whenever you need a new `access_token`. The `refresh_token` does not expire.
