title: How do I specify template parameters when running AWS SAM Local?
body: <p>Using <a href="https://github.com/awslabs/aws-sam-local" rel="noreferrer">AWS SAM Local</a> I can test my serverless application locally, which is awesome.</p>
  
  <p>I can also <a href="https://github.com/awslabs/aws-sam-local#package-and-deploy-to-lambda" rel="noreferrer">deploy to AWS</a>, which apparently takes the same flags as <code>aws cloudformation deploy</code>, so I can pass a parameters file with e.g. application secrets (API keys and such).</p>
  
  <p>However, I can't find anything in <code>aws local start-api --help</code> or in the docs on Github about how to use a parameter file when testing locally.</p>
  
  <p>How do I point to a parameters file to use with my template when running <code>sam local start-api</code>?</p>
