AWS Lambda policy

An AWS Lambda policy contains the connection details that are used by an AWS Lambda Request node when you connect it to an AWS Lambda application.

You can use an AWS Lambda Request node in a message flow to connect IBM® App Connect Enterprise to AWS Lambda applications and issue requests to create, retrieve, update, delete, or invoke functions. The AWS Lambda policy controls, at run time, access to the AWS Lambda application.

The AWS Lambda policy is created when you configure a connection between an AWS Lambda Request node and AWS Lambda by using the Connector Discovery wizard. During the process of discovery, account credentials are stored in the vault and connection details are stored in the AWS Lambda policy. The policy is created with a type of AWS Lambda, and the name of the policy is returned to the AWS Lambda Request node and specified in the Connection tab of the node, in the format {policyProjectName}:policyName.

You can also create, update, or delete an AWS Lambda policy by using the Manage Discovery Connector Policies and Credentials wizard, which you can access by right-clicking the policy project in the IBM App Connect Enterprise Toolkit and then clicking New > Discovery Connector policies and credentials.

You must deploy this policy before message flows that use the policy are started. If you redeploy an AWS Lambda policy, all message flows that are using the policy are stopped and restarted.
