Switch your deep linking from Firebase to Adjust in three simple steps

Google has now deprecated Firebase Dynamic Links (FDL), and will shut the service down completely on August 25, 2025. Effective this date, all existing links will stop working, and new link creation will be disabled. The immediate priority for marketers is to transition to a deep linking solution that can maintain their existing user experience needs and support undisrupted growth via seamless migration. This is where Adjust comes in.

Preparing for the FDL deprecation might seem stressful, but the good news is that transitioning to Adjust unlocks a range of benefits for marketers seeking to continue their deep linking efforts and to level up. 

TrueLink, Adjust’s robust solution for frictionless deep linking, enables marketers to uphold their existing deep linking capabilities across paid, owned, and earned media channels. Part of Adjust’s Engage pillar for customer engagement solutions, TrueLink makes it easy to navigate the transition from Firebase with confidence and uninterrupted performance—all equivalent Firebase links can be easily regenerated and implemented.

TrueLink provides branded short links that work across mobile web, desktop web, push, social, email, messaging/SMS, referral, content sharing, and more—empowering you to improve conversion rates and performance throughout the entire marketing funnel. Adjust also supports deferred deep linking, which ensures a smooth, effortless user experience even if the app is not installed. When users click, install, and open the app, they’ll still be directed to the page the initial link provided.

What’s also beneficial is that by switching from Firebase Dynamic Links to Adjust TrueLink, everything is contained in a single platform. This helps marketers to minimize time spent toggling between tools and promotes a lean, centralized tech stack for smart, fast decisions.

Adjust is now offering a link migration tool based on a Google Sheet with an embedded Apps Script. The tool allows clients to export Firebase Dynamic Links metadata, map parameters, and generate equivalent Adjust links instantly at scale by leveraging Adjust’s Bulk Link Generation API.

Pre-requisites: This guide assumes that you have implemented the Adjust SDK and completed the TrueLink set-up steps.

Adjust’s three-step client migration process

1. Export Firebase Links : Export the Firebase Dynamic Links metadata as a CSV file following this Firebase guide and paste them into the Adjust link migration tool.
2. Map Firebase parameters to Adjust parameters : We provide you with a pre-filled recommended mapping but you can customize this if needed.
3. Generate Links : With a click of the button, you can generate Adjust TrueLinks equivalent to your Firebase links (short or long). Our script automatically leverages our API to create these links in bulk. We recommend running the test migration first to validate the links before running the full migration.

• Use your links with full coverage across owned and earned as well as ad network channels.
