LinkedWhatsAppBusinessAccount

Source: src/AWS/SocialMessaging/LinkedWhatsAppBusinessAccount.ts

A WhatsApp Business Account (WABA) linked to your AWS account through AWS End User Messaging Social.

Managing a Linked Account

import * as AWS from "alchemy/AWS";

const events = yield* AWS.SNS.Topic("WhatsAppEvents", {});

const waba = yield* AWS.SocialMessaging.LinkedWhatsAppBusinessAccount(
  "Business",
  {
    // from the AWS End User Messaging Social console after onboarding
    accountId: "waba-0123456789abcdef0123456789abcdef",
    eventDestinations: [{ eventDestinationArn: events.topicArn }],
    tags: { team: "growth" },
  },
);

Consuming WhatsApp Events

WhatsApp events (inbound messages, message status updates) are delivered exclusively to the SNS topics listed in eventDestinations — there is no separate event source for this service. Compose the resource with AWS.SNS.consumeTopicNotifications on the destination topic:

const events = yield* AWS.SNS.Topic("WhatsAppEvents", {});

const waba = yield* AWS.SocialMessaging.LinkedWhatsAppBusinessAccount(
  "Business",
  {
    accountId: "waba-0123456789abcdef0123456789abcdef",
    eventDestinations: [{ eventDestinationArn: events.topicArn }],
  },
);

// inside a Lambda Function's init effect
yield* AWS.SNS.consumeTopicNotifications(events, (stream) =>
  stream.pipe(
    Stream.runForEach((notification) =>
      Effect.log("whatsapp event", notification.Message),
    ),
  ),
);
