Berbix Node SDK

This Berbix Node library provides simple interfaces to interact with the Berbix API.

Installation

If you are using NPM for package management

npm install berbix

If you are using Yarn for package management

yarn add berbix

Usage

Constructing a client

// Import the Berbix Node library
var berbix = require('berbix');

// Construct the client, providing at least clientId and clientSecret
var client = new berbix.Client({
  clientId: 'your_client_id_here',
  clientSecret: 'your_client_secret_here',
  environment: 'production',
})

Create a transaction

var transactionTokens = client.createTransaction({
  customerUid: "interal_customer_uid", // ID for the user in internal database
  templateKey: "your_template_key", // Template key for this transaction
})

Create tokens from refresh token

// Load refresh token from database
var transactionTokens = berbix.Tokens.fromRefresh(refreshToken)

Fetch transaction data

var transactionData = await client.fetchTransaction(transactionTokens)

Reference

Client

Methods

constructor(options)

Supported options:

  • clientId (required) - The client ID that can be found in your Berbix Dashboard.
  • clientSecret (required) - The client secret that can be found in your Berbix Dashboard.
  • environment - Which environment the client uses, defaults to production.
  • httpClient - An optional override for the default Node HTTP client.
createTransaction(options): Tokens

Creates a transaction within Berbix to initialize the client SDK. Typically after creating a transaction, you will want to store the refresh token in your database associated with the currently active user session.

Supported options:

  • email - Previously verified email address for a user.
  • phone - Previously verified phone number for a user.
  • customerUid - An ID or identifier for the user in your system.
  • templateKey - The template key for this transaction.
fetchTransaction(tokens: Tokens): object

Fetches all of the information associated with the transaction. If the user has already completed the steps of the transaction, then this will include all of the elements of the transaction payload as described on the Berbix developer docs.

refreshTokens(tokens: Tokens): void

This is typically not needed to be called explicitly as it will be called by the higher-level SDK methods, but can be used to get fresh client or access tokens.

validateSignature(secret: string, body: string, header: string): boolean

This method validates that the content of the webhook has not been forged. This should be called for every endpoint that is configured to receive a webhook from Berbix.

Parameters:

  • secret - This is the secret associated with that webhook. NOTE: This is distinct from the client secret and can be found on the webhook configuration page of the dashboard.
  • body - The full request body from the webhook. This should take the raw request body prior to parsing.
  • header - The value in the 'X-Berbix-Signature' header.

Tokens

Properties

accessToken: string

This is the short-lived bearer token that the backend SDK uses to identify requests associated with a given transaction. This is not typically needed when using the higher-level SDK methods.

clientToken: string

This is the short-lived token that the frontend SDK uses to identify requests associated with a given transaction. After transaction creation, this will typically be sent to a frontend SDK.

refreshToken: string

This is the long-lived token that allows you to create new tokens after the short-lived tokens have expired. This is typically stored in the database associated with the given user session.

transactionId: number

The internal Berbix ID number associated with the transaction.

expiry: Date

The time at which the access and client tokens will expire.

Static methods

fromRefresh(refreshToken: string): Tokens

Creates a tokens object from a refresh token, which can be passed to higher-level SDK methods. The SDK will handle refreshing the tokens for accessing relevant data.
