Azure Communication Administration client library for JavaScript

The administration library is used for managing users and tokens for Azure Communication Services. This library also provides capabilities for phone number administration.

Acquired phone numbers can come with many capabilities, depending on the country, number type and phone plan. Examples of capabilities are SMS inbound and outbound usage, PSTN inbound and outbound usage. Phone numbers can also be assigned to a bot via a webhook URL.

Getting started

Prerequisites

• An Azure subscription.
• An existing Communication Services resource. If you need to create the resource, you can use the Azure Portal or Azure CLI.

Installing

npm install @azure/communication-administration

Key concepts

Clients

The administration package exposes two clients. The CommunicationIdentityClient provides methods to manage users and their tokens. The PhoneNumberAdministrationClient provides methods to manage phone plans and numbers.

Phone plans overview

Phone plans come in two types; Geographic and Toll-Free. Geographic phone plans are phone plans associated with a location, whose phone numbers' area codes are associated with the area code of a geographic location. Toll-Free phone plans are phone plans not associated location. For example, in the US, toll-free numbers can come with area codes such as 800 or 888.

All geographic phone plans within the same country are grouped into a phone plan group with a Geographic phone number type. All Toll-Free phone plans within the same country are grouped into a phone plan group.

Searching and acquiring numbers

Phone numbers can be search through the search creation API by providing a phone plan id, an area code and quantity of phone numbers. The provided quantity of phone numbers will be reserved for ten minutes. This search of phone numbers can either be cancelled or purchased. If the search is cancelled, then the phone numbers will become available to others. If the search is purchased, then the phone numbers are acquired for the Azure resources.

Configuring and assigning numbers

Phone numbers can be assigned to a callback URL via the configure number API. As part of the configuration, you will need an acquired phone number, callback URL and application id.

Examples

Authentication

You can get a key and/or connection string from your Communication Services resource in Azure Portal. Once you have a key, you can authenticate the CommunicationIdentityClient and PhoneNumberAdministrationClient with any of the following methods:

Create KeyCredential with AzureKeyCredential before initializing the client

import { AzureKeyCredential } from "@azure/core-auth";
import { CommunicationIdentityClient } from "@azure/communication-administration";

const credential = new AzureKeyCredential(KEY);
const client = new CommunicationIdentityClient(HOST, credential);

Using a connection string

import { PhoneNumberAdministrationClient } from "@azure/communication-administration";

const connectionString = `endpoint=HOST;accessKey=KEY`;
const client = new CommunicationIdentityClient(connectionString);

If you use a key to initialize the client you will also need to provide the appropriate endpoint. You can get this endpoint from your Communication Services resource in Azure Portal.

Usage

CommunicationIdentityClient

Creating an instance of CommunicationIdentityClient

import { CommunicationIdentityClient } from "@azure/communication-administration";

const client = new CommunicationIdentityClient(CONNECTION_STRING);

Creating a new user

Use the createUser method to create a new user.

const user = await client.createUser();

Creating and refreshing a user token

Use the issueToken method to issue or refresh a token for an existing user. The method also takes in a list of communication token scopes. Scope options include:

• chat (Chat)
• pstn (Public switched telephone network)
• voip (Voice over IP)

let { token } = await client.issueToken(user, ["chat"]);

To refresh the user token, issue another token with the same user.

{ token } = await client.issueToken(user, ["chat"]);

Revoking tokens for a user

Use the revokeTokens method to revoke all the issued tokens of a user.

await client.revokeTokens(user);

revokeTokens takes an optional second argument, tokensValidFrom. If this date is provided, revokeTokens will revoke all tokens issued before it. Otherwise, all tokens will be revoked.

Deleting a user

Use the deleteUser method to delete a user.

await client.deleteUser(user);

PhoneNumberAdministrationClient

Creating an instance of PhoneNumberAdministrationClient

import { CommunicationIdentityClient } from "@azure/communication-administration";

const client = new CommunicationIdentityClient(CONNECTION_STRING);

Getting countries

Use the listSupportedCountries method to get a list of the supported countries.

const countries = await client.listSupportedCountries();

for await (const country of countries) {
  console.log(`Country code: ${country.countryCode}`);
  console.log(`Country name: ${country.localizedName}`);
}

Getting phone plan groups

Phone plan groups come in two types, Geographic and Toll-Free. Use the listPhonePlanGroups method to get them.

const countryCode = "US";
const phonePlanGroups = await client.listPhonePlanGroups(countryCode);

for await (const phonePlanGroup of phonePlanGroups) {
  console.log(`Phone plan group id: ${phonePlanGroup.phonePlanGroupId}`);
}

Getting location options

For Geographic phone plans, you can query the available geographic locations. The locations options are structured like the geographic hierarchy of a country. For example, the US has states and within each state are cities.

Use the getPhonePlanLocationOptions method to get the options for a location.

const { locationOptions } = await client.getPhonePlanLocationOptions({
  countryCode: "US",
  phonePlanGroupId: "phonePlanGroupId",
  phonePlanId: "phonePlanId"
});

console.log(`Got location options for: ${locationOptions.labelId}`);

Getting area codes

Fetching area codes for geographic phone plans will require the the location options queries set. You must include the chain of geographic locations traversing down the location options object returned by the getPhonePlanLocationOptions.

Use the getAreaCodes method to get the area codes for geographic phone plans.

const { primaryAreaCodes } = await client.getAreaCodes(
  {
    locationType: "selection",
    countryCode: "US",
    phonePlanId: "phonePlanId",
    locationOptionsQueries
  }
);

Searching for phone numbers

Use the createSearch method to search for phone numbers. This method returns a searchId which should be used to query the status of the search.

const { searchId } = await client.createSearch({
    name: "Phone number search 800",
    description: "Search for 800 phone numbers"
    phonePlanIds: ["phone-plan-id-1"],
    areaCode: "800",
    quantity: 1
});

To get the results of the search use the searchId to call the getSearch method.

const phoneNumberSearch = await client.getSearch(searchId);

Purchasing phone numbers from a search

Use the purchaseSearch method to purchase the phone numbers from your search.

await client.purchaseSearch(searchId);

You also need to call the getSearch method to get the results of your purchase.

Cancel a phone number search

Phone numbers are reserved for 10 minutes when you create a new search. To cancel a search, and make numbers available to other users, call the cancelSearch method with the searchId of the search.

await client.cancelSearch(searchId);

Call the getSearch method to get the results.

Currently, you need to implement your own poller with getSearch to know when the search, purchase and cancel operations have reached a terminal status.
