I’m new to gatling and I couldn’t find information on how to use multiple feeders in a scenario. I want to do the following

val base = “[http://localhost:8480/services](http://localhost:8480/services)”

val data = csv(“biometrics\_data.csv”).queue  
val accessTokens = csv(“access\_tokens\_data.csv”).queue

val scn = scenario(“Test”)  
.feed(data)  
.feed(accessTokens) //adding two feeders dosen’t work ☹

.exec(  
http(“Test all individuals of Biometrics”)  
.get(base+ “/v1/biometrics/${data}?access\_token=${token}”)  
.check(status.is(200))  
)

Where ${token} comes from the feeder AccessTokens and ${data comes from data. Is there a way to do this i found no examples of doing so. Thanks

The feeders work perfectly fine. The problem is your request:  
[https://github.com/excilys/gatling/wiki/HTTP#wiki-query-params](https://github.com/excilys/gatling/wiki/HTTP#wiki-query-params)

You should be writing:  
.get(base+ "/v1/biometrics/${data})  
.queryParam("access\_token", "${token}")

Cheers,
