Using templating in simulations

Use templating in Hoverfly Cloud simulations to create dynamic responses based on request data and other variables.

Templating in Hoverfly Cloud provides a powerful way to render just about anything you want into the response. It uses the well known {{ handlebars }} syntax where the handlebars surround functions which allow you to control information flow.

Important: In order to enable templating you need to explicitly click the "Enable templating" checkbox when crafting your response.

A simple tutorial that covers some of what's possible with templating can be found .

As this is a fairly large topic it is broken up into sections:
