Postman - How to pass a global variable into JSON body
JsonRestRequestPostmanJson Problem Overview
I'm working with Postman right now and I have to do a lot of requests, and in the body I'm passing a JSON content. I would like to know if is there a way to pass the value of a global variable into JSON body. Thank you.
Json Solutions
Solution 1 - Json
If using a raw JSON body:
{
"test key":"{{global variable}}"
}
On sending the request, the curly braces will be replaced with the value of the variable.
Solution 2 - Json
I think what you want to do is described here.
> To use a variable you need to enclose the variable name with double curly braces – {{my_variable_name}}.
Solution 3 - Json
Double curly bracket is working in header parameter, url or inside JSON body. Inside tests you should use globals example: {"url": globals.url} or {"url": globals["url"]}
Solution 4 - Json
You can pass
{
"productId": {{**ProductID**}},
"quantity": 1
}
Where ProductID is your global variable name
in raw format JSON (application/json)
Solution 5 - Json
Yep, double curly brackets is the way to go to achieve this - make sure you have the latest version of Postman (though if you are still running 2014 code when this feature was introduced, shame on you!)
eg:
{
"variable": "{{value}}"
}
See the second paragraph here in the Variables section of the documentation - it specifically mentions the request body.
