Facebook, Instagram, Bitly, Pinterest and others

Some sites don't return the required token_type parameter in their token response. You can tell if you're getting the error “No token type received, will not use the token”:

• Bitly
• Instagram
• LinkedIn does the same but needs even more special attention
• Medium
• Pinterest
• Twitch
• Slack

There is a subclass for code grant flows that ignores the missing token type that you can use: OAuth2CodeGrantNoTokenType.

For Instagram, Pinterest and Medium you also need to set oauth2.authConfig.secretInBody = true (or use secret_in_body in your settings dict) because it expects the client secret in the request body, not the Authorization header.

Facebook

let oauth2 = OAuth2CodeGrantNoTokenType(settings: [
            "client_id": "<app_id>",
            "client_secret": "<app_secret>",
            "authorize_uri": "https://graph.facebook.com/oauth/authorize",
            "token_uri": "https://graph.facebook.com/oauth/access_token",
            "response_type": "token",
            "scope": "email",
            "secret_in_body": true,
            "redirect_uris": ["fb\(<app_id>)://authorize/"] // The "/" at the end is mandatory
        ])

Make sure to register your URL type with URL Schemes as fb<app_id> and Bundle ID on https://developers.facebook.com/ exactly the same (fb<app_id>)
