@beamimpact/web-sdk

The Beam SDK enables brands to connect with their users over shared values, not transactional discounts, to build stronger loyalty. Our integration achieves this by allowing users 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.

The Beam Web SDK provides a set of web components and framework-specific wrappers for integrating Beam components 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 component you want to use at the top of the page:

<script
  type="module"
  crossorigin
  src="https://sdk.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 components can have attributes like class, style, and data-attributes.

Components can also be created using Javascript:

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

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 components 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>

Component Options

Required props for all components:

• 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

Component that integrates into a cart to allow users 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 users
• 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 Component & Post Purchase Component

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

Select Nonprofit Component

• 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

Statsig / A/B Experiment

• Event: beamstatsiginitialized
• Description: Emitted when Statsig has completed assigning experiment variants for the current session. Contains showBeam (whether components should be shown) and stableId (the Statsig session Id).

Post Purchase Component

• 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 component, depending on if the user made a selection before purchase or not.

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

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

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

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

Events

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

Customizing inner components

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://sdk.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 component with the Shopify cart, which allows Beam metadata for the nonprofitId and selectionId to be added to the order as the user 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://sdk.beamimpact.com/web-sdk/v1.36.0/dist/integrations/shopify.esm.js";

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

Post-purchase script:

import { showBeamOrderPageWidgets } from "https://sdk.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,
});

Consent-driven teardown:

If a user withdraws tracking consent, unregisterCartIntegration() stops the listeners set up by registerCartIntegration() and can optionally wipe Beam's local storage/cookies in the same call. It's opt-in — the SDK doesn't watch for a consent signal itself, so this must be wired into your own consent banner/flow.

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

await unregisterCartIntegration(
  { apiKey: "abc123", storeId: 100, chainId: 10 },
  { clearStorage: true }, // also clear Beam's localStorage/cookies; defaults to false
);

Utils

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

1. waitForElement returns a Promise which resolves when the selector appears.
2. errors contains Beam custom error classes.
3. events contains Beam custom events classes / event names.
4. clearBeamStorage clears all Beam-related localStorage keys and cookies for a given config; useful for a standalone consent-driven reset that isn't tied to unregisterCartIntegration.

import { clearBeamStorage } from "https://sdk.beamimpact.com/web-sdk/v1.36.1/dist/integrations/utils.js";

clearBeamStorage({ apiKey: "abc123", domain: "my-store.com" });

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

try {
  const parentElement = await waitForElement("#my-selector", { timeout: 1000 });
  parentElement.appendChild(component);
} 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 components 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
