Variables

Postman stores important API values in variables. Variables can be reused in different requests. If you change the value of a variable, the new value is used instead across all those requests.

When you first import the Sign API v2 environment, it contains just three variables: baseUrl, api_key, and api_secret

environment

You can see how a variable is used in an Authentication request:

variables

Postman substitutes the variable {{baseUrl}} with the value stored in the Sign API v2 Environment: https://kassensichv-middleware.fiskaly.com/api/v2

So this request is actually POSTed to https://kassensichv-middleware.fiskaly.com/api/v2/auth
