Before and After Example​

Configuration​

{
   "type": "split",
   "config": {
       "index": 1,
       "separator": "|,."
   }
}

Example Chains​

req_body() -> json_path(path="tags") -> split(index=0, separator=",")

This will extract the tags field from the request body and get the first tag from a comma-separated list.

http_req_header(header="Accept-Language") -> split(index=0, separator=",;")

This will extract the Accept-Language header and get the primary language preference.

res_body() -> json_path(path="path") -> split(index=2, separator="/")

This will extract a path field from the response body and get the third segment from a forward-slash separated path.
