How to Protect Mobile Apps With DeviceMATCH™ API Using AI

Last updated June 10, 2026 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Validate DeviceMATCH™ API in Mobile apps.

What Is DeviceMATCH™ API?

DeviceMATCH™ API is a capability within IDAnchor™ that allows applications to compare a device’s current IDAnchor value against previously observed values using Appdome’s secure server-side matching service.

The IDAnchor value is a tamper-resistant device identifier derived from deep, hard-to-alter characteristics of the device and its environment. When submitted to the DeviceMATCH™ API service, the current IDAnchor value is compared against historical values and a similarity score between 0 and 1 is returned.

  • A score of 1 indicates an exact match and suggests the device is the same trusted device observed previously.
  • Lower scores indicate partial matches, which may result from legitimate device changes, such as operating system upgrades or time zone changes, or from suspicious activity such as device spoofing or emulator use.
  • A score below 0.65 typically indicates elevated risk because the device characteristics have changed significantly. For high-risk workflows, such as device binding, Appdome recommends using a threshold of 0.9 or higher to ensure that only verified devices are trusted.

Comparing IDAnchor values over time helps detect fraud, validate sessions, protect user accounts, and identify suspicious activity.

 

How Appdome Protects Mobile Apps With DeviceMATCH™ API

Applications can use the DeviceMATCH™ API to submit the current IDAnchor value to Appdome’s secure matching service and receive a similarity score indicating how closely the current device matches previously trusted devices. This allows applications to incorporate device trust and continuity signals into fraud detection, account protection, authentication, and risk-based decision workflows.

Prerequisites for Using Appdome's DeviceMATCH™ API Plugins:

To use Appdome’s mobile app security build system to Validate DeviceMATCH™ API , you’ll need:

How to Implement Validate DeviceMATCH™ API in Mobile Apps Using Appdome

On Appdome, follow these simple steps to create self-defending Mobile Apps that Validate DeviceMATCH™ API without an SDK or gateway:

  1. Designate the Mobile App to be protected.

    1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.

    2. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
    3. DeviceMATCH™ API is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
  2. Select the defense: DeviceMATCH™ API.

      1. Create and name the Fusion Set (security template) that will contain the DeviceMATCH™ API feature as shown below:
        fusion set that contains DeviceMATCH™ API

        Figure 1: Fusion Set that will contain the DeviceMATCH™ API feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the DeviceMATCH™ API feature to your Fusion Set via the Appdome Console.

      3. When you enable IDAnchor™ you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains DeviceMATCH™ API.

        Figure 2: Fusion Set that displays the newly added DeviceMATCH™ API protection
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      4. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below): fusion Set Detail Summary image

        Figure 3: Fusion Set Detail Summary

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:
        1. Refer to the Appdome API Reference Guide for API building instructions.
        2. Look for sample APIs in Appdome’s GitHub Repository.
    1. Add the DeviceMATCH™ API feature to your security template.

      1. Navigate to Build > IDAnchor tab > Android IDAnchor section in the Appdome Console.
      2. Toggle On IDAnchor™ > DeviceMATCH™ API.
        Note: The checkmark feature DeviceMATCH™ API is enabled by default, as shown below. DeviceMATCH™ API option

        Figure 4: Selecting Validate DeviceMATCH™ API

    2. Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.
    Congratulations!  The DeviceMATCH™ API protection is now added to the mobile app
  3. Certify the DeviceMATCH™ API feature in Mobile Apps

    After building DeviceMATCH™ API, Appdome generates a Certified Secure™ certificate to guarantee that the DeviceMATCH™ API protection has been added and is protecting the app. To verify that the DeviceMATCH™ API protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: DeviceMATCH™ API shown in Certificate secure

    Figure 5: Certified Secure™ certificate

    Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that DeviceMATCH™ API has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that DeviceMATCH™ API and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for DeviceMATCH™ API Intelligence and Control in Mobile Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when DeviceMATCH™ API is detected. To consume and use Threat-Events™ for DeviceMATCH™ API in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for DeviceMATCH™ API shown below.

The specifications and options for Threat-Events™ for DeviceMATCH™ API are:

With Threat-Events™ enabled (turned ON), Mobile developers can get detailed attack intelligence and granular defense control in Mobile applications and create amazing user experiences for all mobile end users when DeviceMATCH™ API is detected.


The following is a code sample for native Mobile apps, which uses all values in the specification above for DeviceMATCH™ API:


Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.



Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using DeviceMATCH™ API. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
