AWS API Gateway DEFAULT_5XX and DEFAULT_4XX

Terraform Providers

Hi all, I’m configuring CORS for API Gateway and want to set default responses. Does anyone know how to set the default 400 and 500 responses for API Gateway?

I can see there is a aws_api_gateway_gateway_response but that requires a “response_type” and the default responses dont have that,

Thanks,

I was searching for the same answer. This ended up working for me:

resource "aws_api_gateway_gateway_response" "cors" {
  rest_api_id         = aws_api_gateway_rest_api.lambdas.id
  response_type       = "DEFAULT_4XX"

  response_parameters = {
    "gatewayresponse.header.Access-Control-Allow-Origin"  = "'${aws_cloudfront_distribution.app.domain_name}'"
    "gatewayresponse.header.Access-Control-Allow-Methods" = "'OPTIONS'"
  }
}
