Understand OAuth permissions before connecting AI

Before connecting an AI workflow to a business account, write down what it should be able to read and change. Then compare that list with the provider's permission screen. A connection that works technically may still grant more access than your task needs.

This guide is for owners and administrators reviewing a first connection or an expansion of an existing one. The outcome is a short permission record you can revisit when staff, software, or workflows change. Provider details were checked on October 10, 2026; always compare them with the consent screen you actually receive.

Understand the grant you are making

OAuth lets an application receive delegated access to a service. In Google's documented flow, the application requests scopes, the person grants permissions, and the application receives an access token or a code it can exchange for one. The application must inspect the scopes actually granted because they can differ from its request. Google OAuth overview.

For a business review, translate each permission into an ordinary sentence: this connection can read these records, create these objects, or send from this account. Keep the provider's exact scope name beside that translation so the technical reviewer can verify it.

Also identify the app receiving the grant. A familiar sign-in provider does not make every requesting application appropriate for your business. Check the app identity, selected account, publisher information, and purpose before continuing. If the account is organization-managed, involve its administrator when required.

Separate data coverage from action power

Permissions have at least two dimensions: which information is accessible and what can be done with it. A read permission can cover a very large collection. A permission limited to selected files can still allow changes to those files.

Google Drive illustrates this distinction. Its drive.readonly scope permits viewing and downloading all Drive files. Its drive.file scope permits creating new files or modifying files the user opens or shares with the app through the documented selection flow. The latter is narrower in file coverage but is not a read-only permission. Drive scope reference.

Ask for the narrowest available combination that fits the workflow. Where a provider cannot express your desired boundary, record the mismatch. Application-level restrictions may reduce exposure, but they should not be described as a narrower provider grant. Sometimes the sensible pilot uses approved sample documents instead of a broad account connection.

Separate a connection from a task approval

A provider grant establishes technical access. Your business still needs rules about when the workflow may use it. A tool capable of sending email should not infer permission to send every draft it creates.

Write separate decisions for reading, saving a draft, modifying an internal record, and contacting someone. Name the reviewer for consequential actions. Specify any excluded records, audiences, or data categories. Keep these rules visible in the workflow brief rather than relying on a vague instruction to be careful.

An application's permission checks should remain effective even if generated text recommends something outside the brief. Ask the implementer to demonstrate a denied operation, such as requesting an unapproved record, rather than showing only a successful summary.

Understand access over time

Google documents that access tokens have limited lifetimes and that a refresh token can obtain new ones. Refresh tokens can also stop working, including when access is revoked or affected by administrative policy. Token lifecycle guidance.

For your setup, ask whether access continues after you close the browser and where connection credentials are protected. Passwords, access tokens, and refresh tokens should not be pasted into prompts, ordinary intake forms, or troubleshooting messages. Support staff should be able to investigate with a connection identifier and redacted error details.

If access fails, the workflow should explain which dependency is unavailable and pause affected work. Reconnecting with a more powerful account is a new access decision. Do not treat it as the automatic answer to every error.

A fictional permission review

Harbor Sample Design is a fictional studio testing summaries of approved service descriptions. The owner initially assumes that a read-only Drive connection means access to one folder. The review reveals that the proposed grant covers a broader set of files.

The team revises the pilot to use a small set of fictional documents supplied through a supported selection route. It records any remaining write capability and disables writing in the application workflow. Before using business information, the owner will decide whether that combination is acceptable. This is a planning example, not a report of a customer deployment or a claim that every connector supports file selection.

Complete the connection worksheet

Use one record per connection:

1. Name the business account, requesting application, and grant owner.
2. List the exact provider scopes and their plain-language meaning.
3. Identify accessible records and the permitted operations on them.
4. Record what the workflow needs and any extra rights the grant includes.
5. Identify who approves changes, outgoing messages, or broader access.
6. Record whether background access exists and who handles connection failures.
7. Locate the provider's removal controls and the application's disconnect control.
8. Test removal with harmless sample data and check pending jobs afterward.

Google provides account controls for reviewing and removing linked-app access. Check the particular link type: sign-in, account access, and agent permissions can represent different relationships. Manage linked apps.

Finish by recording what happened in the removal test, including anything you could not verify. Disconnecting future access also leaves a separate question about information already copied into the workflow. Ask about its retention and deletion process before adding real data.

Bring the completed worksheet to an InstallAI setup discussion. It gives you a concrete way to discuss useful access, unresolved permission gaps, and a connection you can deliberately turn off.
