hello,  
I’m new to this and trying to do a flow where 1 send request will create a variable called orgID from the response it gets and pass it on to the next send request.

the first flow when I run it, generates this below.  
[{ “id”: “11223344”, “name”: “somename”, “url”: “[https://someurl](https://someurl)”, “api”: { “enabled”: true }, “licensing”: { “model”: “co-term” }, “cloud”: { “region”: { “name”: “North America” } } } ]

I want to create a collection variable called myOrg using the tests section and have myOrg have the value 11223344.

this is the tests I have so far but it’s just dumping the entire response back on console starting from id which isn’t what I need, I need myOrg to contain only the value 11223344.

var jsonData = JSON.parse(responseBody);  
pm.collectionVariables.set(“myOrg”, pm.response.json.id);  
console.log(pm.response.json(“myOrg”));

thanks for any help.

On closer inspection, it looks like you have an array.

```auto
const response = 

[{ "id": "11223344", "name": "somename", "url": "https://someurl", "api": { "enabled": true }, "licensing": { "model": "co-term" }, "cloud": { "region": { "name": "North America" } } }]

console.log(response);

pm.test('response is an array', () => {
    pm.expect(response).to.be.an('array');
});

console.log(response[0].id)

```

Therefore the following should work.

```auto
const response = pm.response.json()
pm.collectionVariables.set("myOrg", response[0].id);
console.log(pm.CollectionVariables.get("myOrg"));

```

fantastic,  
it gives me “11223344”, how would I remove the " please and get only 11223344?

Postman uses JavaScript under the hood.

```auto
const response = pm.response.json()
pm.collectionVariables.set("myOrg", parseInt(response[0].id));
console.log(pm.CollectionVariables.get("myOrg"));
