There are a handful of key concepts you need to understand how to effectively configure and use Slumber. You can read about each one in detail on its linked API reference page.
The collection is the main form of configuration. It defines a set of request recipes, which enable Slumber to make requests to your API.
A recipe defines which HTTP requests Slumber can make. A recipe generally correponds to one endpoint on an API, although you can create as many recipes per endpoint as you'd like.
Templates are Slumber's most powerful feature. They allow you to dynamically build URLs, query parameters, request bodies, etc. using predefined or dynamic values.
A profile is a set of static template values. A collection can contain a list of profiles, allowing you to quickly switch between different sets of values. This is useful for using different deployment environments, different sets of IDs, etc.
