How to persist Postman variables
Blog post from Postman
In Postman, variables are an essential feature that allows users to store and manage values efficiently across collections, environments, requests, and scripts, facilitating collaboration and dynamic workflows. Understanding the distinction between current and initial values is crucial for persisting variables between local sessions and runs. Variables can be managed manually through the variable editor or programmatically using the Postman API, particularly when using collection-based monitors or the command line tool Newman. Users can persist variables throughout collection runs by employing local variables and configuring options to maintain variable values. The process involves updating initial values to reflect current values, thus enabling seamless persistence across different sessions and runs. The ability to access and update variables using the Postman API is crucial for maintaining data integrity, especially when handling sensitive information like API keys within workflows.
