# Cloud Providers

You can authenticate with Claude using any of these three methods:

1. Direct Anthropic API (default)
2. Amazon Bedrock with OIDC authentication
3. Google Vertex AI with OIDC authentication

For detailed setup instructions for AWS Bedrock and Google Vertex AI, see the [official documentation](https://docs.anthropic.com/en/docs/claude-code/github-actions#using-with-aws-bedrock-%26-google-vertex-ai).

**Note**:

- Bedrock and Vertex use OIDC authentication exclusively
- AWS Bedrock automatically uses cross-region inference profiles for certain models
- For cross-region inference profile models, you need to request and be granted access to the Claude models in all regions that the inference profile uses

## Model Configuration

Use provider-specific model names based on your chosen provider:

```yaml
# For direct Anthropic API (default)
- uses: anthropics/claude-code-action@beta
  with:
    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
    # ... other inputs

# For Amazon Bedrock with OIDC
- uses: anthropics/claude-code-action@beta
  with:
    model: "anthropic.claude-3-7-sonnet-20250219-beta:0" # Cross-region inference
    use_bedrock: "true"
    # ... other inputs

# For Google Vertex AI with OIDC
- uses: anthropics/claude-code-action@beta
  with:
    model: "claude-3-7-sonnet@20250219"
    use_vertex: "true"
    # ... other inputs
```

## OIDC Authentication for Bedrock and Vertex

Both AWS Bedrock and GCP Vertex AI require OIDC authentication.

```yaml
# For AWS Bedrock with OIDC
- name: Configure AWS Credentials (OIDC)
  uses: aws-actions/configure-aws-credentials@v4
  with:
    role-to-assume: ${{ secrets.AWS_ROLE_TO_ASSUME }}
    aws-region: us-west-2

- name: Generate GitHub App token
  id: app-token
  uses: actions/create-github-app-token@v2
  with:
    app-id: ${{ secrets.APP_ID }}
    private-key: ${{ secrets.APP_PRIVATE_KEY }}

- uses: anthropics/claude-code-action@beta
  with:
    model: "anthropic.claude-3-7-sonnet-20250219-beta:0"
    use_bedrock: "true"
    # ... other inputs

  permissions:
    id-token: write # Required for OIDC
```

```yaml
# For GCP Vertex AI with OIDC
- name: Authenticate to Google Cloud
  uses: google-github-actions/auth@v2
  with:
    workload_identity_provider: ${{ secrets.GCP_WORKLOAD_IDENTITY_PROVIDER }}
    service_account: ${{ secrets.GCP_SERVICE_ACCOUNT }}

- name: Generate GitHub App token
  id: app-token
  uses: actions/create-github-app-token@v2
  with:
    app-id: ${{ secrets.APP_ID }}
    private-key: ${{ secrets.APP_PRIVATE_KEY }}

- uses: anthropics/claude-code-action@beta
  with:
    model: "claude-3-7-sonnet@20250219"
    use_vertex: "true"
    # ... other inputs

  permissions:
    id-token: write # Required for OIDC
```
