Introduction

The document provides an example of receiving access token via Postman (pre-request script).

Instructions

Download Postman - https://www.postman.com/
Run it
Create a new request:

Choose method POST and enter the URL:

https://{{authService}}/api/v2/OpenId/service/

Copy the Pre-request Script and configure user, password and pbxHost:

const user = 'extension';
const pass = 'password';
const pbxHost = 'https://<domain>.wildixin.com';

const authService = 'auth.wildix.com';
pm.variables.set('authService', authService);

pm.sendRequest({
    url: `${pbxHost}/api/v1/personal/token/?service=${authService}`,
    method: 'GET',
    header: {
        'Authorization': 'Basic ' + btoa(`${user}:${pass}`)
    },
    body: {}
}, function(err, response) {
    if (err || response.code !== 200) {
        throw new Error('Personal token not received');
    }
    const personalToken = response.json().result.token;
    console.log('PERSONAL TOKEN', personalToken);

    pm.sendRequest({
        url: `https://${authService}/api/v2/Token/`,
        method: 'GET',
        header: {
            'Authorization': `Bearer ${personalToken}`
        },
        body: {}
    }, function(err, response) {
        if (err || response.code !== 200) {
            throw new Error('Access token for auth not received');
        }

        const authAccessUserToken = response.json().result.accessToken;
        console.log('AUTH ACCESS USER TOKEN', authAccessUserToken);
        pm.variables.set('authAccessUserToken', authAccessUserToken);
    });
});

Go to the Authorization tab and choose the type and set dynamic variable:

{{authAccessUserToken}}
