@beamimpact/web-sdk

The Beam SDK enables brands to connect with their customers over shared values, not transactional discounts, to build stronger loyalty. Our integration achieves this by allowing customers to (a) choose a nonprofit where the brand will donate part of their purchase from a set of curated options and (b) track their cumulative impact with every order towards quantifiable goals.

Beam takes care of all the nonprofit management and compliance, impact tracking, UI styling and dynamic campaignization.

Integrations

The Beam Web SDK provides a set of web components and framework-specific wrappers for integrating Beam widgets into an e-commerce website.

Installation

@beamimpact/web-sdk is available on NPM or via CDN.

CDN

Most e-commerce applications will load Beam over the CDN.

Include the script for the widget you want to use at the top of the page:

<script
  type="module"
  crossorigin
  src="https://production-beam-widgets.beamimpact.com/web-sdk/v1.36.1/dist/components/community-impact.js"
></script>

Versions

Replace v1.36.1 with the latest version available on NPM

type="module" is required to parse the bundle correctly
This script will register the Beam custom element so it can be used anywhere in the page
You may need to adjust your page's content security policy to allow scripts and images from beamimpact.com.

NPM

npm install @beamimpact/web-sdk

Import the component in your app's JavaScript:

import { BeamCommunityImpact } from "@beamimpact/web-sdk/dist/components"; // Native web component
import { BeamCommunityImpact } from "@beamimpact/web-sdk/dist/react"; // React component

Using Beam

Web Components

Beam web components are custom elements, so they can be used in HTML:

<beam-impact-overview chainId="1000"></beam-impact-overview>

Because they are standard HTML elements, Beam widgets can have attributes like class, style, and data-attributes.

Components can also be created using Javascript:

const widget = document.createElement("beam-select-nonprofit");
widget.chainId = 1000;
widget.apiKey = "abc123";
const parent = document.querySelector("#sidebar-cart .footer");
parent.appendChild(widget);

The elements can also have children which show up before the script loads or if it fails to parse:

<beam-impact-overview chainId="1000"> Fallback or loading content </beam-impact-overview>

React

Beam provides a React wrapper for the web components.

Key differences: event handler callbacks are exposed for the Beam events, and the components are named using the JSX-friendly uppercase format.

import { BeamSelectNonprofit } from "@beamimpact/web-sdk/dist/react";
import { events } from "@beamimpact/web-sdk/dist/integrations/utils";

<BeamSelectNonprofit
  apiKey={"abc-123"}
  chainId={1000}
  onNonprofitSelect={(event: events.BeamNonprofitSelectEvent) => {
    const { selectedNonprofitId, nonprofitName } = event.detail;
    // do something
  }}
/>;

Serverside-Rendering

(ie, NextJS)

The Beam Widgets run clientside and save data (such as the user's nonprofit selection) in localStorage and cookies.

Use next/dynamic to lazy-load components async on the client instead of the server.

"use client";
import dynamic from "next/dynamic";

const BeamSelectNonprofit = dynamic(() => import("@beamimpact/web-sdk/dist/react/select-nonprofit"), {
  loading: () => null,
  ssr: false,
});

Debug Mode

Add the debug attribute to a component to show an error state in the DOM when errors occur. Otherwise, check for console logs.

<beam-impact-overview chainId="1000" debug></beam-impact-overview>

Widget Options

Required props for all widgets:

apiKey - Beam API Key

Optional props:

baseUrl - (provided by Beam) - URL for a dev or staging API
lang - en, fr, etc. Language code for a Beam-supported translation target

beam-community impact

Shows impact progress cards for each nonprofit supported by a brand, for brand impact pages, etc.

<beam-community-impact apiKey="abc123" chainId="1" cardStyle="image | icon"></beam-community-impact>

chainId = Beam customer ID
cardStyle = image or icon - visual style to use for impact cards

beam-cumulative-impact

Shows total impact in terms of nonprofit funding goals - e.g., "9,000 lbs of ocean trash removed"

<beam-cumulative-impact apiKey="abc123" chainId="1"></beam-cumulative-impact>

chainId = Beam customer ID

beam-select-nonprofit

Widget that integrates into a cart to allow customers to support a nonprofit as they check out.

<beam-select-nonprofit apiKey="abc-123" storeId="1"> Select a nonprofit </beam-select-nonprofit>

storeId = Beam ID for site, i.e., EU or US online store (optional) - used to show relevant nonprofits to customers
countryCode & postalCode = If storeId is not provided, location information can be provided instead (optional)
cart = Usually set automatically by the cart integration (see below), the cart property allows customizing the nonprofits shown based on the items in the cart

Events

document.addEventListener("beamnonprofitselect", (evt) => {
  const { selectedNonprofitId, selectionId, nonprofitName } = evt.detail;
  // ...
});

Event Types

Select Nonprofit Widget & Post Purchase Widget

Event: beamnonprofitselect
Description: Emitted when the end user selects a nonprofit in the Beam widget, and when the previous selection was restored automatically

Select Nonprofit Widget

Event: beamcartchange
Description: Emitted when Beam detects that cart contents have changed, and when items are added to the cart for the first time
Event: beamnonprofitselectionremoved
Description: Emitted when the nonprofit selection is removed from deselection or due to nonprofit cohort change

Post Purchase Widget

Event: beamordercreated
Description: Emitted when an order is registered with Beam for the first time, but NOT on repeat visits, page refreshes, etc.

beam-post-purchase

A wrapper component that registers transactions and renders either the beam-impact-overview or beam-redeem-transaction widget, depending on if the user made a selection before purchase or not.

<script src="https://production-beam-widgets.beamimpact.com/web-sdk/v1.36.1/dist/components/post-purchase.js"></script>

<beam-post-purchase apiKey="abc123"></beam-post-purchase>

const widget = document.createElement("beam-post-purchase");

// Config values:
widget.apiKey = "abc123"; // Required
widget.storeId = 100; // Beam Store ID
widget.countryCode = "GB"; // 2-letter country code for order
widget.postalCode = "11111"; // String - postalCode in country-specific format
widget.orderId = String(10101); // partner provides ID
widget.email = "test@beamimpact.com"; // customer email
widget.cartTotal = 100.01; // Cart total before tax
widget.currencyCode = "USD"; // "CAD" etc.
widget.cart = {
  schema: {
    source: "shopify",
  },
  content: {
    items: [{ sku: "PRODUCT-100" }],
  },
}; // see OpenAPI spec for cart formats
widget.discountCodes = ["PROMO10", "CLEARANCE_50"]; // discount / promo codes
widget.lang = "en"; // en | fr Language
widget.domain = "example.com"; // [Optional] Base domain of the store, if subdomains for store and checkout differ
widget.debug = false; // boolean

Events

document.addEventListener("beamnonprofitselect", (evt) => {
  const { selectedNonprofitId, nonprofitName } = evt.detail;
  // ...
});

Customizing inner widgets

Use beam-post-purchase::part(impact-overview) or beam-post-purchase::part(redeem-transaction) to apply CSS.

Integrations

Cart Integration

Integrating Beam with your cart allows for customizing the available nonprofits based on the items in the cart.

import { updateCart } from "https://production-beam-widgets.beamimpact.com/web-sdk/v1.36.1/dist/integrations/cart.js";

// on cart change
const cart = {
  cartId: "cart_100", // external cart ID (from partner site, optional)
  subtotal: 90,
  itemCount: 1,
  currencyCode: "USD",
  content: {
    items: [
      { remoteProductIdentifier: "sku-123", localAmount: 50 },
      { remoteProductIdentifier: "sku-456", localAmount: 40 },
    ],
  },
};

const beamConfig = {
  apiKey: "abc-123",
  storeId: 123,
  domain: "my-tld.com", // optional, domain or subdomain to set cookies on
  baseUrl: "", // optional, Beam API url (staging or production)
};

await updateCart(beamConfig, cart);

Shopify

The registerCartIntegration() function integrates the Beam Nonprofit Select widget with the Shopify cart, which allows Beam metadata for the nonprofitId and selectionId to be added to the order as the customer goes through the checkout flow, and to track the cart token and cart value for the Beam ROI calculation.

Add event tracking script to main layout:

<script type="module" async crossorigin>
  import { registerCartIntegration } from "https://production-beam-widgets.beamimpact.com/web-sdk/v1.36.0/dist/integrations/shopify.esm.js";

  registerCartIntegration({
    apiKey: "abc123",
    storeId: 100,
    chainId: 10,
  });
</script>

Post-purchase script:

import { showOrderPageWidgets } from "https://production-beam-widgets.beamimpact.com/web-sdk/v1.36.0/dist/integrations/shopify.esm.js";

await showBeamOrderPageWidgets({
  apiKey: beam.apiKey,
  chainId: beam.chainId,
  storeId: beam.storeId,
  orderId, // From Liquid
  email, // From Liquid
  cartTotal, // From Liquid
  cart, // Cart line items
  currencyCode, // From Liquid
  countryCode, // From Liquid
  postalCode, // From Liquid
  parentSelector: ".step__sections", // CSS selector
  lang: "en", // From Liquid
  baseUrl: beam.baseUrl,
  debug: false,
});

Utils

Several utilities are exposed which making integrating with existing applications easier.

waitForElement returns a Promise which resolves when the selector appears.
errors contains Beam custom error classes.
events contains Beam custom events classes / event names.

import {
  waitForElement,
  errors,
  events,
} from "https://production-beam-widgets.beamimpact.com/web-sdk/v1.36.1/dist/integrations/utils.js";

try {
  const parentElement = await waitForElement("#my-selector", { timeout: 1000 });
  parentElement.appendChild(widget);
} catch (err) {
  if (err instanceof errors.BeamError) {
    /* do something */
  }
}

window.addEventListener(BeamNonprofitSelectEvent.eventName, async (event) => {});

Integrations

Statsig A/B Testing

Beam has a prebuilt integration for A/B testing with Statsig.

import { StatsigPlugin } from "@beamimpact/web-sdk/dist/integrations/statsig";
import { init, getConfig } from "@beamimpact/web-sdk/dist/integrations/beam";

const beam = await init({
  apiKey: "",
  chainId: 1,
  storeId: 1,
  domain: "my-store.com", // in case site uses subdomains for different pages
  plugins: [new StatsigPlugin({ statsigApiKey: "" })],
});

Initializing the Statsig plugin will automatically log statsig_init, cart_created, and order_created events.

To manually log additional events:

beam.plugins.statsig.logEvent(eventName, eventValue, metadataObject);

Setup for A/B tests is async. Waiting for Beam A/B test setup to be ready in other scripts:

const beam = getConfig();
// Wait for promise to resolve
await beam.readyPromise; // resolves when plugins are all ready
// OR use event listeners
if (beam.status !== "ready") {
  beam.addEventListener("beamstatuschange", (event) => {
    const status = event.detail.status;
    if (status === "ready") doSomething(beam);
    else if (status === "error") handleError(event.detail.error);
  });
}

Visibility

Once initialized, all Beam widgets have display: none unless user is assigned to A/B test group that shows Beam.

To hide additional elements, add the CSS className beam-sync-visibility to them. Elements with this class will automatically have display: none if the user can't see Beam.

To access the experiment state in JavaScript:

import { getConfig } from "@beamimpact/web-sdk/dist/integrations/beam";

getConfig().plugins.statsig.experiments.shouldShowBeam; // boolean
