Choosing between collection variables vs. environment variables

NOTE: Environment variables always override collection variables.

Important: Postman never read values form "Initial value" column ever.

Inheriting authorization from authorization defined in collection settings

Beware Beware Beware that you must remove "Inherit Authorization" from the signin/login requests as shown in below screenshot otherwise your' backend may intercept those requests badly. (WARNIN: In slasher it actually does).

Setting variable at collection level:

var jsonData = pm.response.json();

// 1. setting in currently active environment (MOST COMMONLY NEEDED, Date: 28 May, 2023)
pm.environment.set("TOKEN1", jsonData.token);

// 2. setting collection variable
pm.collectionVariables.set("TOKEN1", jsonData.token);

// 3. setting globally
pm.globals.set("TOKEN1", jsonData.token);

Thats how you set collection specific variables:

Thats how you export a postman collection:

There are three types of variables-

Socket.io Server Requests

- You can choose client version now:
- Set url of socket now (connects automatically to: localhost:PORT/socket.io):
- You can set authorization header with socket like that (even though browsers don't allow setting headers for socket connections yet ~Eric Slasher Project Notes):
- Listening to event and sending event (see next screenshot as well):
How do we get the return value (Acknowledgement) from the event as we can see the return value of the event handler in the code:
You can write documentation for a postman requets like that:

In a request payload you can now write comments with // and /* */ format by adding that pre-script code

// Strip JSON Comments
if (pm?.request?.body?.options?.raw?.language === 'json') {
    const rawData = pm.request.body.toString();
    const strippedData = rawData.replace(
        /\\"|"(?:\\"|[^"])*"|(\/\/.*|\/\*[\s\S]*?\*\/)/g,
        (m, g) => g ? "" : m
    );
    pm.request.body.update(JSON.stringify(JSON.parse(strippedData)));
}

// To set Content-Type again (see the original stackoverflow answer's comment section):
// pm.request.upsertHeader({key: 'Content-Type', value: 'application/json'});
