Node.js Client Library for Start

Prerequisites

Before using this library, you must have:

• API key(s)

Installation

• package not published yet

Initialization

const client = new StartClient(API_KEY);

it is also possible to change the key anytime.

client.key = OTHER_KEY;

subsequent calls will use the new key.

Usage

This library uses promises, so making calls is usually as follows

// init a client
const client = new StartClient(API_KEY);

// get customer list
client.listCustomers()
.then((customers) => {
    // process customers
}, (err) => {
    // handle error here
});

Errors

in error handlers you can get more information about the error,

// init a client
const client = new StartClient(BAD_KEY);

// get customer list
client.listCustomers()
.then((customers) => {
    // not called
}, (err) => {
    if (err.isValidationError) {
        // a validation error occurs when you provide 
        // missin or invalid arguments to a functions
        console.log(err.details);
    }
    // check if it is a server (500) error
    else if (err.isServerError) {
        console.log('Server error!!!');
    } else {
        // error object exposes debug properties

        // error.type can be 'request', 'processing', 'banking' or 'authentication'
        console.log('Error type:', err.type);

        // error.code is a string that identifies the error
        console.log('Error code:', err.code);

        // error.message is a human readable explaintion
        console.log('Error message:', err.message);

        // error.extras is an object that provides bad params if any
        console.log('Error extras:', err.extras);
    }
});
