How to use Unauthorized API Access Signals with MobileBOT™ Defense Using AI

Last updated July 9, 2026 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Enforce Unauthorized API Access Signals in Mobile apps.

What are Unauthorized API Access Signals?

The Unauthorized API Access Signals feature within Appdome’s MobileBOT™ Defense allows developers to select which device and application security signals contribute to Session Risk classification for protected API requests. By analyzing device and app risk factors such as root access, Magisk, Frida toolkits, emulators, and simulators, Unauthorized API Access Signals ensures that connections are only made from trusted devices. This feature is essential in identifying and mitigating risks associated with compromised or modified devices, helping to safeguard sensitive data and transactions. The Unauthorized API Access Signals feature is essential for evaluating device trust and generating Session Risk classifications that backend systems can use to make risk-based access decisions, aligning with compliance standards that emphasize device integrity for secure transactions.

How Appdome Protects Mobile Apps with Unauthorized API Access Signals?

Unauthorized API Access Signals allows Appdome to evaluate selected device and application security signals, such as root access, emulators, Magisk, Frida, and other supported detections. Based on the configured signals, Appdome classifies API requests as Safe or At-Risk and reports the resulting session status to supported backend services and Web Application Firewalls (WAFs). Organizations can then use this classification to enforce their own security policies and determine how API requests should be handled.

Prerequisites for Using Appdome's Unauthorized API Access Signals Plugins:

To use Appdome’s mobile app security build system to Enforce Unauthorized API Access Signals , you’ll need:

How to Implement Enforce Unauthorized API Access Signals in Mobile Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Enforce Unauthorized API Access Signals 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. Unauthorized API Access Signals is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
  2. Select the defense: Unauthorized API Access Signals.

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

        Figure 1: Fusion Set that will contain the Unauthorized API Access Signals feature

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

      3. When you select the Unauthorized API Access Signals you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Unauthorized API Access Signals.

        Figure 2: Fusion Set that displays the newly added Unauthorized API Access Signals 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 Unauthorized API Access Signals feature to your security template.

      1. Navigate to Build > Anti Bot tab > MobileBOT™ Defense section in the Appdome Console.
      2. Toggle On > Unauthorized API Access Signals.
        Unauthorized API Access Signals option

        Figure 4: Selecting Enforce Unauthorized API Access Signals

      3. Optional Configuration with Unauthorized API Access Signals:
        1. Click Manage API Signals next to Unauthorized API Access Signals to select the device and application security signals that should contribute to Session Risk classification. The selected signals determine whether protected API requests are classified as Safe or At-Risk.

        2. Extra configuration image for Unauthorized API Access Signals
    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 Unauthorized API Access Signals protection is now added to the mobile app
  3. Certify the Unauthorized API Access Signals feature in Mobile Apps

    After building Unauthorized API Access Signals, Appdome generates a Certified Secure™ certificate to guarantee that the Unauthorized API Access Signals protection has been added and is protecting the app. To verify that the Unauthorized API Access Signals protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Unauthorized API Access Signals 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 Unauthorized API Access Signals has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Unauthorized API Access Signals and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Unauthorized API Access Signals Intelligence and Control in Mobile Apps

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

The specifications and options for Threat-Events™ for Unauthorized API Access Signals are:

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


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.
