Branch.iO Dynamic Link

1. Branch.io​

We would like to inform you about an important update regarding the Firebase Dynamic Link service. As per the notification from Firebase, the service will be discontinued on August 25th, 2025. This means that users who have recently created a Firebase account may not be able to create dynamic links for their accounts.

In order to ensure a seamless transition and to provide an alternative solution, we are introducing Branch.io as a new option for dynamic link feature in the FluxStore app. Branch.io is a powerful platform that will enable you to continue using dynamic links for your app even after the Firebase service shuts down.

We have chosen Branch.io because it offers cost-effective pricing compared to other services for dynamic links. You can check out the pricing details here: https://www.branch.io/pricing/

We recommend all users to integrate Branch.io into their FluxStore app to avoid any disruptions in the dynamic link functionality. Detailed documentation on how to integrate Branch.io into FluxStore will be provided to assist you with the process.

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.

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.

  • 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.
