Batches allow you to create a large number of shipments at one time, and retrieve details and shipping labels for them all at once.
Authentication and identification are handled in the same step in the EasyPost API by providing one of your API keys in every request. The EasyPost API uses Basic Auth, and only accepts requests sent over SSL (HTTPS). EasyPost API keys come in two modes: test, and production. While you're using a test API key you will never be charged for postage and none of the requests will appear in your live mode reporting.
