sipgateio-node Build Status

A JavaScript library for

Get Started


For use in node applications you can install with

npm install sipgateio --save

Alternatively, a bundled version can be obtained from the github releases page.
Or use a CDN like jsDelivr instead:

Available Functionality

For example a Text Message can be send with following code:

import { sipgateIO, createSMSModule } from 'sipgateio';

const client = sipgateIO({ username: 'username', password: 'password' });
const sms = createSMSModule(client);
	from: '+4901570000000',
	to: '+491579999999',
	message: 'Lorem Ipsum',

The following features are already implemented in the current version of this library:


Send text messages, either instantly or scheduled. The caller ID can be set from the sipgate web interface, the default is the string "sipgate".


Send any PDF file as a fax to a single number.


Initiate a call between two phones of your choice – no matter if inside your sipgate account or outside.

Webhook Settings

Configure the webhook functionality of Currently, you can set URLs and whitelist extensions for triggering webhooks as well as toggle the debug log.


Import contacts in CSV format into your sipgate account.


Creating a Client

You can connect the client by passing a valid OAuth token (You have to implement the OAuth flow yourself):

const client = sipgateIO({
	token: '<valid Token>',

As alternative you can also pass your credentials to the API-Client which will use Basic Auth. (Remember: This way is not recommended)

const client = sipgateIO({
	username: '<your username>',
	password: '<your password>',

Possible authentication objects:

interface BasicAuthCredentials {
	username: string;
	password: string;
interface OAuthCredentials {
	token: string;

The sipgateIO method accepts your valid sipgate credentials as defined in the AuthCredentials type and returns a Client. The client contains as members the supported modules (sms, fax, call, etc.).


The SMS module provides the following functions:

async function send(sms: ShortMessage): Promise<void>;
async function schedule(sms: ShortMessage, sendAt: Date): Promise<void>;

Note: sendAt can be 30 days in advance at max.

Note: you should be aware that the request will take a short time to be processed. Values for sendAt should not just be a few seconds in the future. If sendAt is in the past an error will be thrown.

The ShortMessage type requires the following fields:

interface ShortMessage {
	smsId: string;
	to: string;
	message: string;


interface ShortMessage {
	from: string;
	to: string;
	message: string;


The fax module provides the following functions:

async function send(fax: Fax): Promise<SendFaxSessionResponse>;
async function getFaxStatus(sessionId: string): Promise<FaxStatus>;

The send function allows you to send a fax by passing an object with the following fields:

interface Fax {
	to: string;
	fileContent: Buffer;
	filename?: string;
	faxlineId?: string;

and returns an SendFaxSessionResponse:

interface SendFaxSessionResponse {
	sessionId: string;

By using getFaxStatus and passing the sessionId you received from the send function, you will receive one of the following values:

enum FaxStatus {


The call module provides the following function:

async function initiate(
	newCallRequest: CallData
): Promise<InitiateNewCallSessionResponse>;

The CallData contains the following fields:

interface CallData {
	deviceId?: string;
	from: string;
	to: string;
	callerId?: string;

The InitiateNewCallSessionResponse contains only a session ID:

interface InitiateNewCallSessionResponse {
	sessionId: string;

CallData details

The following table shows valid parameter combinations

to from callerId deviceId
number extension - -
number extension number -
number extension number extension
number number - extension
number extension - extension
number number number extension

The displayed number at the callee device is determined by a hierarchy:

If not set it falls back to the next stage:

  1. callerId
  2. deviceId (related phone number)
  3. from (related phone number if from is an extension)

The param deviceId is only mandatory if from is not an extension.

Valid extension types are e, p, x and y.

extension type phone type
e VoIP phone
p user phoneline
x external phone
y mobile phone

Scenario 1: basic call

const call = createCallModule(client);
const callData = {
	from: 'e14',
	to: '+4921165432',


Behavior: The phone with extension e14 rings first, after pick-up the callee is called. The default number associated with e14 is displayed at the callee device.

Scenario 2: custom caller id

const callData = {
	from: 'p0',
	to: '+4921165432',
	callerId: '+4917012345678',


Behavior: Same situation as previous example, but displayed number is now callerId (see hierarchy).

Scenario 3: group call

const callData = {
	from: '+4921123456',
	deviceId: 'e14',
	to: '+4921165432',


If the from number refers to a group of phones rather than a single one all phones in the group will ring and the first to be picked up will establish the call with the to.

The deviceId is needed for billing and determines the number which will be displayed at the to device. For instance, e14 has the default number '+4921156789'.

Webhook Settings

What is a webhook?

A webhook is a POST request that makes to a predefined URL when a certain event occurs. These requests contain information about the event that occurred in application/x-www-form-urlencoded format.

The webhook settings module provides the following functions to update settings:

async function setIncomingUrl(url: string): Promise<void>;
async function clearIncomingUrl(): Promise<void>;

These two functions allow for the setting and clearing of the URL to be called when a webhook is triggered by an incoming call.

async function setOutgoingUrl(url: string): Promise<void>;
async function clearOutgoingUrl(): Promise<void>;

Analogous functions exist for the URL that handles outgoing calls.

async function setWhitelist(extensions: string[]): Promise<void>;
async function clearWhitelist(): Promise<void>;
async function disableWhitelist(): Promise<void>;

The whitelist specifies extensions that should trigger webhooks. By default, webhooks are enabled for all phoneline and group extensions. This behavior is restored by calling disableWhitelist. The disableWhitelist completely removes the whitelisting and enables all phoneline and group extensions.

async function setLog(value: boolean): Promise<void>;

The setLog function toggles, the function to display all incoming and outgoing events, which have been sent to your Incoming and Outgoing Url. These parameters can be set using these functions: setIncomingUrl and setOutgoingUrl.


The contacts module provides the following functions:

interface ContactImport {
	firstname: string;
	lastname: string;
	address?: Address;
	phone?: PhoneNumber;
	email?: Email;
	organization?: string[];

interface ContactsModule {
	import: (contact: ContactImport, scope: Scope) => Promise<void>;
	importFromCsvString: (csvContent: string) => Promise<void>;
	importVCardString: (vcardContent: string, scope: Scope) => Promise<void>;
	exportAsCsv: (scope: ExportScope) => Promise<string>;
	exportAsVCards: (scope: ExportScope) => Promise<string[]>;
	exportAsSingleVCard: (scope: ExportScope) => Promise<string>;

The import method:

It takes a valid ContactImport Object and creates a Contact in the requested Scope.

The importFromCsvString method:

It takes a valid CSV-formatted string (columns separated by ",") containing at least the following fields:

  • firstname
  • lastname
  • number

These fields may be provided in an arbitrary order. Additional fields as well as empty lines will be ignored. Empty records (i.e. just separators) produce a warning but no error. The same is true for strings containing only the header row.



The importVCardString method:

It takes a valid VCard 4.0 string, containing at least the following fields:

  • name contains firstname and lastname
  • number

The exportAsCsv method:

It returns a csv strings containing all contacts for the given scope

The exportAsVCards method:

It returns mulitple vCard-strings containing all contacts for the given scope

The exportAsSingleVCard method:

It returns a vCard-address-book containing all contacts for the given scope


The PRIVATE Scope contains all contacts created by yourself and not shared with other people.

The SHARED Scope includes all contacts created by anyone in your organization and are therefore shared with other people.

The INTERNAL Scope contains the contacts which are created by sipgate such as a contact for any webuser in your organization.

Adress and Numbers:

You can only save one address and one number using the Format.

npx can be used to run the code examples:

npx ts-node some_example.ts

Privacy Note

This library sets the following headers for every request made to the sipgate REST-API to obtain statistics about versions currently in use and to differentiate from sipgate software:

  • X-Sipgate-Client
  • X-Sipgate-Version
You can’t perform that action at this time.
