Placeholders

Placeholders are strings wrapped in double braces, like {{this}}. They can be the whole value of a string or can be a substring, for example: {{host}}/api/{{version}}/hello.

Resolvers

Placeholders can be given a value through different resolvers. These resolvers have a defined order and the first one providing a value will be the one that is used. If no resolver has a value for the placeholder then the request will fail unless the flag --allow-unresolved is provided.

The order of resolution is:

1. Environment variables. They must match perfectly the placeholder and are case-sensitive.
2. Input parameters, these will be input by the user when the request is executed.
3. Variables, these are defined in a standard table similar to query params or headers, but this one is only aimed to provide values for placeholders.
