Branch.iO Dynamic Links

1. Branch.io​

Since Firebase Dynamic Links will be deprecated on August 25, 2025, it's time for a smooth transition.

This guide will show you how to use Branch.io to create dynamic links for your app.

Plus, we've built FluxBuilder Dynamic Links for FREE just for you! It provides a powerful, native, and pre-built deep linking solution that fits perfectly into your app. Create dynamic links with ease.

2. Setup​

2.1 Sign up account​

To begin using Branch.io's services, please create an account by clicking on the following link: https://dashboard.branch.io/. If you already have an account, simply sign in by visiting: https://dashboard.branch.io/login.

2.2 Configuration on Branch.io​

2.2.1 Environment​

Branch.io provides two environments - LIVE and TEST mode. First, switch to the TEST mode and configure all the Branch.io settings to ensure the app is working perfectly. Once everything is set up and tested in the TEST mode, you can then easily transition to the LIVE mode.

2.2.2 Configuration app information​

Click on the Configuration, section, and this image shows the complete setup after filling in all the required information.

Note: Branch.io may require adding a credit card to unlock certain feature. However, you will only be charged if you exceed the usage limits as mentioned in this link.

Explain:

💠 Default URL: Your fallback URL for mobile devices that do not have a specified redirect.

💠 Android:

  • Android URI Scheme: Choose a unique URI scheme name for your app to avoid conflicts with other apps. A good practice is to use a scheme that matches your app's domain. You can refer to the rule for creating URI schemes from Branch.io for more detailed recommendations.

  • Android Package Name: Fill YOUR-ANDROID-PACKAGE-NAME.

  • Enable App Links: TICK ☑ and fill SHA256 Cert Fingerprints. To get the SHA256 key, please follow this instruction.

NOTE: If the Google Play Store displays both certificates, "App signing key certificate" and "Upload key certificate", you need to copy both of these SHA256 keys into Branch.IO and separate them with a comma. For example: KEY-APP,KEY-UPLOAD.

💠 iOS:

  • iOS URI Scheme: Choose a unique URI scheme name for your app to avoid conflicts with other apps. A good practice is to use a scheme that matches your app's domain. You can refer to the rule for creating URI schemes from Branch.io for more detailed recommendations.

  • Enable Universal Links: TICK ☑️
  • Bundle Identifiers: Input your iOS bundle identifier.

  • Apple App Prefix: Get it in Apple Developer dashboard as this image.
