feat(oauth): narrow Google Sheets scope to drive.file + Picker#1451himanshudube97 wants to merge 6 commits into
Conversation
Google's OAuth verification team rejected `spreadsheets.readonly` under the minimum-scope policy: that scope reads every spreadsheet in the user's Drive, while Dalgo only ever syncs the one sheet the user names. `drive.file` grants exactly the files the user hands us through the Google Picker, and it is non-sensitive — no verification, no demo video, no unverified-app screen, no annual re-review. The grant Google records is (oauth client, user, file id) and is durable, so the stored refresh_token keeps reading that sheet on Airbyte's schedule, headless. Because the browser now has to run the Picker, the callback stashes Google's access_token next to the refresh_token, and a new endpoint hands it out — with the Picker's API key and app id — for a ref the caller owns. The refresh_token still never leaves the backend. Ref TTL goes 120s -> 600s: browsing Drive for a file does not fit in two minutes. Follow-up: the UI must source spreadsheet_id from the Picker, never from a pasted link — an id the user never picked is not readable under drive.file.

Google OAuth web server include_granted_scopes true previously granted scopes narrowing requested scopes refresh token behavior
💡 Result:
When using Google OAuth 2.0 with the include_granted_scopes parameter set to true, you enable incremental authorization [1][2][3]. This allows your application to request additional scopes in context while retaining access to scopes previously granted by the user [1][3][4]. If the authorization request is granted, the resulting access token covers the combined set of scopes—both the newly requested scopes and any scopes the user previously granted to your application [1][2][3]. Regarding refresh token behavior and the narrowing of scopes: 1. Persistence of Access: Setting include_granted_scopes to true ensures that subsequent access tokens obtained via your refresh token can represent the full, cumulative set of granted permissions [1][5]. 2. Refresh Token Scope: A refresh token is typically associated with the grant that produced it. When you perform incremental authorization, you often receive an access token, but you may not always receive a new refresh token unless one is specifically granted by the authorization server (e.g., when requested with access_type=offline and prompted for consent) [1][5]. 3. Avoiding Scope Narrowing: If you find that your access tokens are "narrowing" to only the most recently requested scopes, it is often because the application is failing to use the combined scope state correctly or is initiating a new authorization flow that does not account for existing grants [6][5]. To maintain the full scope, ensure that: - Your application maintains the comprehensive list of required scopes [4][7]. - You include include_granted_scopes=true in your authorization requests [1][3]. - If you are managing tokens, ensure you are utilizing the access token that corresponds to the desired (combined) authorization state [1][5]. It is important to note that incremental authorization is intended for web server flows and specific client-side implementations; it is not supported in the same way for installed/native application flows [6][8]. If you are experiencing unexpected scope behavior, verify that your client ID configuration and authorization requests are consistently using the include_granted_scopes parameter [9][3].

🌐 Web query:
site:developers.google.com/identity/protocols/oauth2/web-server include_granted_scopes previously granted scopes authorization request
💡 Result:
The include_granted_scopes parameter is an optional parameter used in OAuth 2.0 authorization requests, primarily within the Google Identity ecosystem, to facilitate incremental authorization [1]. When set to true, this parameter enables an application to request access to new scopes while maintaining access to scopes that the user had previously granted to the application [1]. If the authorization request is successful, the resulting access token will encompass both the newly requested scopes and the previously granted scopes [1]. This is considered a best practice for applications that require different levels of access at different times, as it allows for a smoother user experience by preventing the need to re-request all permissions whenever a new, specific scope is required [1]. If this parameter is not used, a new authorization request for additional scopes might result in an access token that only contains the newly requested scopes, effectively dropping the previously granted ones unless they are explicitly re-requested.
Citations:
Disable incremental scope aggregation for the drive.file consent flow.
include_granted_scopes=true can add scopes previously granted to the OAuth client to the new access token. A user who previously granted spreadsheets.readonly can therefore retain broad spreadsheet access when the flow requests only drive.file.
Set include_granted_scopes to false and assert q["include_granted_scopes"] == ["false"] in test_airbyte_api.py.

The bridge existed because the OAuth flow asked for `spreadsheets.readonly`, a sensitive scope whose Google verification takes weeks; a service account skipped verification entirely. The flow now asks for `drive.file`, which is non-sensitive and needs no verification, so the reason is gone. Existing sources are unaffected. Airbyte stores the key in the source's own connectionConfiguration and has no notion of whose key it is — it is just service JSON — and on re-save the masked secret round-trips untouched, exactly as every other connector's password does. So there is nothing left to fall back to, and no need for the env var to stay set. Deleting the injector also removes a bug it was about to cause. Now that Google sign-in ships, a saved source can carry the Client (OAuth) branch, whose `service_account_info` is absent by design. The injector read that empty slot as "use Dalgo's key" and rewrote the whole credentials block — so editing an OAuth source without re-authenticating (a rename, an advanced field) silently swapped the user's own Google grant for Dalgo's service account, which holds no share on their spreadsheet. The check ran against the same substituted credentials, so it passed and the failure only surfaced at the next sync. `sourceDefName` goes with it: it was added to carry the connector name to the injector and nothing else reads it.
