Leverage useful helper functions within Hoverfly Cloud's templating engine to simplify and enhance your API simulations.

Concatenate two strings

{{ concat <string1> <string2> }}

Search and replace text in a string

{{ replace <string-to-search> <string-to-replace> <replacement-string> }}

This can be particularly useful when dealing with the results of a JSONPath query that returns an array, as these are space delimited strings of values.

{{ split <delimited-string> '<delimiter>' }}

If you are following a pattern where you want a single request/response pair to return different HTTP response codes based on the outcome of logic, then you can do that using the following function:

{{ setStatusCode <any-valid-http-response-code> }}
