The following example Lambda functions return the required CORS headers: Node. Enabling CORS support for proxy integrationsįor a Lambda proxy integration or HTTP proxy integration, your backend is responsible for returning the Access-Control-Allow-Origin,Īccess-Control-Allow-Headers headers, because a proxy integration doesn't return an integration response. Modify the integration response to return theĪccess-Control-Allow-Origin header for all CORS-enabled methods for at least all 200 responses.
