Hi Jean, If you are using our client libraries, you don't need to manually set the access token in your request as the library itself is generating an access token in the background using your refresh token. If your access token is about to expire or has already expired, the client library will automatically generate a new access token using the refresh token.
About setting or reusing the access token, this is already incorporated in the client libraries, and you don't need to do this manually. There is also no method currently that would manually set the access token in your request. If you want to reuse your access token for your separate requests, then you can use the refresh token instead as this is linked to your access token at a time. Also, if you are not using our client libraries, you can refer to the generic OAuth2 guide <https://developers.google.com/identity/protocols/OAuth2>. The guide provides a step by step instructions on how to authenticate via the authentication type of your choice. For example, if you will be authenticating via the "Installed application" type <https://developers.google.com/identity/protocols/OAuth2InstalledApp>, it provides the whole steps on how to generate the refresh and access tokens and how to call an API method <https://developers.google.com/identity/protocols/OAuth2InstalledApp#callinganapi> via HTTP or CURL request. If you have further clarifications on this, I suggest that you create a new forum thread so we can better track your concern.
