Postman API auth

POSTMAN.md

Reuse this as much as you want, this is supposed to be helpful testing APIs with Postman or using Postman in general without worry about the authentication tokens.

Modifications are welcome :)

put_in_scripts.js

if (pm.environment.has("auth_path") && pm.environment.has("auth_token") && !pm.environment.get("auth_token")) {
    pm.sendRequest({
        url: pm.variables.get("base_url") + pm.variables.get("auth_path"),
        method: 'POST',
        header: {
            'Content-Type': 'application/json',
        },
        body: {
            mode: 'raw',
            raw: JSON.stringify({
                'username': pm.variables.get("username"),
                'password': pm.variables.get("password"),
            })
        }
    }, function (err, response) {
        pm.environment.set("auth_token", response.json().access_token);
    });
