# MuleSoft Flex for wizard The Wallarm Edge node can be connected to your MuleSoft Flex Gateway in either [synchronous](https://docs.wallarm.com/installation/inline/overview.md) and [asynchronous](https://docs.wallarm.com/installation/oob/overview.md) mode - without blocking any requests. Follow the steps below to set up the connection. **1. Upload the Wallarm policy to MuleSoft Exchange** 1. Download the provided code bundle for your platform. 1. Extract the policy archive. 1. Ensure the machine you will use to publish the policy meets [all necessary requirements](https://docs.wallarm.com/installation/connectors/mulesoft-flex.md#requirements). 1. Navigate to MuleSoft Anypoint Platform → **Access Management** → **Business Groups** → choose your organization → copy its **business group ID**. 1. In the extracted policy directory → `Cargo.toml` → `[package.metadata.anypoint]` → `group_id`, specify the copied group ID: ```toml ... [package.metadata.anypoint] group_id = "" definition_asset_id = "wallarm-custom-policy" implementation_asset_id = "wallarm-custom-policy-flex" ... ``` 1. [Authenticate with Anypoint CLI](https://docs.mulesoft.com/anypoint-cli/latest/auth) in the same terminal session where you are working with the policy: ``` anypoint-cli-v4 conf username anypoint-cli-v4 conf password '' ``` 1. Build and publish the policy: ```bash make setup # Installs dependencies and PDK CLI make build # Builds the policy make release # Publishes a new production version of the policy to Anypoint ``` Your custom policy is now available in your MuleSoft Anypoint Platform Exchange. **2. Attach the Wallarm policy to your API** You can attach the Wallarm policy to either an individual API or all APIs. 1. To apply the policy to an individual API, navigate to Anypoint Platform → **API Manager** → select the desired API → **Policies** → **Add policy**. 1. To apply the policy to all APIs, go to Anypoint Platform → **API Manager** → **Automated Policies** → **Add automated policy**. 1. Choose the Wallarm policy from Exchange. 1. Specify the Wallarm node URL including `http://` or `https://` in the `wallarm_node` parameter. 1. If necessary, modify [other parameters](https://docs.wallarm.com/installation/connectors/mulesoft-flex.md#configuration-options). 1. Apply the policy.
