Integrate App percy with Codemagic

Integrate App percy with Codemagic, a CI-CD platform built for mobile app teams

Follow these steps to integrate App percy with Codemagic:

Configuring Codemagic environment variables

Start by configuring PERCY_TOKEN, our project-specific, write-only API token. It can be found in your App percy project settings.

In your Codemagic application settings, go to Environment variables and add PERCY_TOKEN. Enable Secure to keep the value hidden in build logs.

Alternatively, you can export the variable as part of your codemagic.yaml build script:

Commit, branch, and pull request information

App percy auto-detects Codemagic builds via the CM_BUILD_ID environment variable and reads the following native Codemagic variables:

• CM_COMMIT — commit SHA
• CM_BRANCH — branch name
• CM_PULL_REQUEST — set to true when the build is triggered by a pull request
• CM_PULL_REQUEST_NUMBER — pull request number (when the build was triggered by a PR)

If any of these are not set in your environment, configure your environment to include PERCY_COMMIT, PERCY_BRANCH, and PERCY_PULL_REQUEST. See the environment variables docs page for more details.

Run your tests

With your environment configured, run your App percy snapshots via your test suite or another mechanism. Your App percy build will be created with the correct meta-data.

Parallelized build processes

If you parallelize your build across multiple workflows or machines, PERCY_PARALLEL_TOTAL and PERCY_PARALLEL_NONCE need to be configured. App percy automatically uses Codemagic’s CM_BUILD_ID as the parallel build nonce. Set PERCY_PARALLEL_TOTAL to the total number of parallel builds.
