URL encode Postman variable?

I use Postman for REST API testing and parametrize tests with global variables.

I should put a phone number into GET request: /path/get?phone={{phone}} but leading + sign in the phone number is interpreted as a space.

What is the syntax to URL encode global variables in Postman? Is it possible to run JS encodeURIComponent() on variable in URL?

I am late but still worth it:

Just highlight and right click the part of url you want to encode. Select encodeURIComponent

That's it.

Use the Pre-request scripts (it's next to body) for this:

var encoded = encodeURIComponent({{phone number}});

or

var encoded = encodeURIComponent(pm.environment.get("phone number"));

and to proceed, use:

pm.environment.set("encoded phone number", encoded);

And set your URL to /path/get?phone={{encoded phone number}}

Just a shortcut to Mohhamad Hasham' answer.

You can encode and decode direct in the Params Value field:

The trick is to get your environment variable in the pre-request script and then set it after encoding it

    var encoded = encodeURIComponent(pm.environment.get("phone"));
    pm.environment.set("encoded phone number", encoded);

I came across this question looking for an answer to a similar question. For me, the variable was a JSON object. The endpoint I needed to hit was expecting an object list as a query parameter and I have no way to change that to be the request body.

As much as some of the answers helped, I ended up coming up with a combined solution. Also, some of the code given in other answers is outdated as Postman has updated their API over the years, so this uses methods that work on 7.22.1.

pm.environment.set("basicJSON", '[{"key1":"value1","key2":"value2"},{"key1":"value1","key2":"value2"}]')
var encoded = encodedURIComponent(pm.environment.get("basicJSON"))
pm.environment.set("encodedJSON", encoded)

This solution requires that both basicJSON and encodedJSON exist as environment variables. But what was important for me was the ease of editing the object. I didn't want to have to decode/encode constantly to change values, and I didn't want to have to open the environment variables dialogue. Also, it's important to note the single-quotes around the object. Excluding them or using double-quotes would cause Postman to send something like "[object Object]" which is useless to an endpoint expecting actual JSON.

I had similar problem with braces { and } in query parameter.
By turning off the following setting it started working for me.

This will work as well:

var encoded = encodeURIComponent(pm.request.url.query.get("phone"));
pm.request.url.query.remove("phone");
pm.request.url.query.insert("phone", encoded);

Click the Params button to open the data editor for URL parameters. When you add key-value pairs, Postman combines everything in the query string above. If your URL already has parameters - for example, if you are pasting a URL from some other source. Postman splits the URL into pairs automatically. https://www.getpostman.com/docs/v6/postman/sending_api_requests/requests
