Aligning Codemagic Build Index with TestFlight Build Numbers

[ayusha259]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

In my current CI/CD setup with Codemagic, I receive Slack notifications upon build completion. The notifications follow this format:

#[build_index] [app_version]
For example: #5 1.2.16.

I’d like to customize the build index to match the numbering scheme of my previous CI/CD workflow. Specifically, I want to start the build index at a specific value (e.g., 200) and have it increment from there with each subsequent build, rather than starting at the default 1.

Expected results

The goal is to align the build index with the actual build numbers used in TestFlight for iOS or for App distribution for Android builds.

Actual results

The build index starts at 1 and increments automatically with each new build. I cannot find an option to set a custom starting value for the build index to align with my previous CI/CD workflow or match the build numbers used in TestFlight or Android builds.

Build id (optional)

Hello @ayusha259,
At the moment, customizing the starting value of the build index isn't directly supported. I was thinking using the Slack API Integration as described here - https://docs.codemagic.io/knowledge-others/slack-api-integration/ could suit your use-case. With this you can use of built-in environment variables e.g. BUILD_NUMBER or PROJECT_BUILD_NUMBER during the build in scripts to customize this. Please let me know if this will help in your case?

Hello @ayusha259,
I was reviewing this again and I can help reset your build index to the number you would like this to begin with. Let me explain this further with an example just to be sure this is your use case.
For this application, my current build index is 98 and I get a slack notification with:

Resetting this on our end to build index 101, my next build will now have a build index 102:

If this suits your use-case, kindly share with me your app_id, workflow_id and the new build index. If you are using the workflow editor you can get it from the url in your UI:

If yaml, your workflow name will be needed instead of workflow_id e.g

workflows:
  random_workflow:
    name: random workflow name

In this case, the workflow name is random_workflow
