# Evaluate feature flags in GitHub Actions

Copy page

ConfigCat's [CLI GitHub Actions](https://github.com/configcat/cli-actions) has the ability to evaluate feature flags in GitHub Action workflows. This feature lets you use your feature flag values or create conditional steps in your workflow.

### Prerequisites[​](#prerequisites "Direct link to Prerequisites")

* An SDK key for the ConfigCat config/environment pair that contains the feature flags you want to evaluate.

### Example[​](#example "Direct link to Example")

The following example shows how you can evaluate ConfigCat feature flags and use the evaluated results in subsequent steps.

```yaml
name: Evaluate ConfigCat feature flags
on: push
jobs:
  example-job:
    runs-on: ubuntu-latest
    steps:
      - name: Evaluate feature flags
        id: flags
        uses: configcat/cli-actions/eval-flag@v1
        with:
          sdk-key: ${{ secrets.CONFIGCAT_SDK_KEY }}
          flag-keys: |
            flag1
            flag2
          user-attributes: |
            id:1234
      
      - name: Step depending on flag1
        if: steps.flags.outputs.flag1 == 'true'
        run: echo "flag1 is true"

      - name: Step depending on flag2
        if: steps.flags.outputs.flag2 == 'true'
        run: echo "flag2 is true"

```

The results of the flag evaluations are stored in the step outputs named with each flag's key.
