Can I use OAuth 2.0 to authenticate with the Figma API

OAuth 2.0 Authentication for Figma API

Figma supports OAuth 2.0 for authentication to the Figma REST API. Here are the general steps:

1. Register your application: You need to register your application on the Figma Developer site to get a `client_id`.

2. Redirect the user to the Figma OAuth authorization URL: When your application needs to access the Figma API on behalf of a user, you redirect the user to the Figma OAuth authorization URL, passing your `client_id` and the requested scopes (e.g. `file_read`).

3. Figma prompts the user to authenticate and grant access: Figma will prompt the user to authenticate and grant your application the requested permissions.

4. Figma redirects the user back to your application: After the user authenticates and grants access, Figma will redirect the user back to a callback URL you specified, passing an authorization code.

5. Exchange the authorization code for an access token: Your application then exchanges the authorization code for an access token using your `client_id` and `client_secret`.

6. Use the access token to make API requests: Once you have the access token, you can use it to make authenticated API requests by including it in the `Authorization` header as a Bearer token.

Note that the `file_read` scope is currently the only scope available for OAuth 2.0 with the Figma API. Figma is working on adding more granular scopes in the future to allow apps to request only the permissions they need.

Also, the OAuth 2.0 flow for Figma plugins is slightly different, as the plugin runs in a sandboxed environment. In this case, you need to use a separate web page hosted on your own server to handle the OAuth 2.0 flow. The Figma documentation has more details on this process.

Overall, using OAuth 2.0 is the recommended way to authenticate with the Figma API, as it provides a secure and user-friendly way for your application to access Figma resources on behalf of the user.
