Postman - How can I pass array as variable - postman

Question

Is there the possibility to use an array variable inside postman?
e.g. inside the body of a request:
{
"myData" : {{arrayVariable}}
}
and inside the data file:
{
"arrayVariable": ["1", "2", "3"]
}

Answer 1

It's possible, you can even add your own keys

Answer 2

You can create a JSON body like this:
{
"myData" : [
{{arrayVariable}}
]
}
And the variable like this:
arrayVariable: "1", "2", "3"
where arrayVariable is the key and "1", "2", "3" is the value.

Answer 3

using variable with a same name will give you an array

Answer 4

Postman environment variables are meant to just save data as string, so here you are the workaround to pass array as environment variable/data file to Postman as a string like this:
{
"arrayVariable": '["1", "2", "3"]'
}
Then, add the following piece of code to parse this variable in pre-request script in Postman like this:
var x = JSON.parse(postman.getEnvironmentVariable("arrayVariable"));
postman.setEnvironmentVariable("arrayVariable", x);

Answer 5

Please create your body request like below
{
"myData" : ["{{arrayVariable}}"]
}
and there is no change required for data file.you can use as it is.
{
"arrayVariable": ["1", "2", "3"]
}
It will work definatly.

Answer 6

The only solution worked for me was something like the answer MickJagger provided, but I think it needs some clarifications.
The JSON data file should be something like this:
[
{
"anArray": "1, \"2\", 3.0, \"Foo\", false"
}
]
which it's value is a string, escaping the quotations for string elements.
(Note that this example differs from example provided by original question, to cover more use cases.)
The variables is as MickJagger said:
{
"value": [{{anArray}}]
}
Maybe other solutions works on previous postman versions, but this solution is tested on postman's latest version (by the time of publishing this answer), i.e. v7.34.0 .
