Google Sign-in Configuration

Overview

This guide walks you through setting up Google Sign-In for your app. You'll create a Google Cloud Project, configure OAuth clients for iOS and Android, and gather the credentials needed for Median App Studio.

Before you start

Make sure you have:

• A Google Cloud account (create one here)
• Your app's iOS Bundle ID (example: co.median.ios.soclogin)
• Your app's Android Package Name (example: co.median.android.soclogin)
• Your app's Android SHA-1 certificate fingerprint (get from the Median.co team if we're signing your app)
• Admin access to Google Cloud Console

Step 1: Create a Google Cloud project

ℹ️

Existing Google Cloud Project
If you already have a Google Cloud Project for your website, you can use it. Skip to Step 2 to create your OAuth clients.

1.1 Create new project

1. Log in to Google Cloud Console.
2. Click New Project.
3. Enter a Project name (example: MySocialLoginApp).
4. Click Create.

Step 2: Configure the OAuth consent screen

Before creating OAuth clients, you need to configure the OAuth consent screen that users will see during sign-in.

2.1 Access OAuth consent screen

1. In Google Cloud Console, go to APIs & Services → OAuth consent screen.

2.2 Configure the consent screen

1. User Type: Select your audience type.
2. Click Create.
3. Fill in App Information:
   • App name: Your app's name (shown to users)
   • User support email: Valid support email
   • App logo: Optional app logo
4. Add Developer contact information.
5. Review and acknowledge Google API Services: User Data Policy.
6. Click Save and Continue.

ℹ️

Firebase Users
If you use Firebase Console, make sure to configure the Support Email in Firebase Console → Settings → General → Public Settings → Support Email

Step 3: Create OAuth clients

You need to create three separate OAuth clients: one for iOS, one (or more) for Android, and one for web.

1. Navigate to APIs & Services → Credentials.
2. Click Create Credentials → Select OAuth client ID.
3. For Application type, select iOS.
4. Enter a descriptive Name for your iOS app.
5. Enter your iOS Bundle ID (example: co.median.ios.soclogin)
6. Click Create.
7. Save your iOS Client ID.

Create iOS URL Scheme:

You will also need to create an iOS URL Scheme from this Client ID by reversing it.

Example:

• Client ID: 843254985318-c1q9b8809pul43h3q5u1q5t6ki0l10en.apps.googleusercontent.com
• iOS URL Scheme: com.googleusercontent.apps.843254985318-c1q9b8809pul43h3q5u1q5t6ki0l10en

Step 4: Verify the OAuth client dashboard

Your Google Cloud Credentials dashboard should now show:

• iOS Client ID
• Android Client ID (one or more if including debug clients)
• Web Client ID

🏁

Configuration Complete
You've successfully configured Google Cloud. Next, add these credentials to the Median App Studio.

Step 5: Add credentials to the Median App Studio

Now that your Google Cloud OAuth clients are configured, add these credentials to the Median App Studio:

1. Log in to the Median App Studio.
2. Navigate to: Native Plugins → Social Login → Settings.
3. Enter your Google Sign-In Configuration:

📘

Multiple Android Clients If you created multiple Android OAuth clients (production + debug), use your production Android Client ID in the Median App Studio.

4. Click Confirm and Save.
5. Rebuild your app for the changes to take effect.
