# WhatsApp Business setup

> Configure the WhatsApp Business provider with Meta credentials.

Use `whatsappBusiness.config(...)` with credentials from Meta for Developers.

## Config

```ts theme={null}
whatsappBusiness.config({
  accessToken: "your-access-token",
  phoneNumberId: "your-phone-number-id",
  appSecret: "your-app-secret",
});
```

| Option          | Description                                                    |
| --------------- | -------------------------------------------------------------- |
| `accessToken`   | Permanent or system-user token from Meta for Developers.       |
| `phoneNumberId` | The phone number ID for the business account sending messages. |
| `appSecret`     | App secret used to verify webhook payload signatures.          |

Find these values in your WhatsApp Business app settings on [Meta for Developers](https://developers.facebook.com/).

## Example

```ts theme={null}
import { Spectrum } from "spectrum-ts";
import { whatsappBusiness } from "spectrum-ts/providers/whatsapp-business";

const app = await Spectrum({
  providers: [
    whatsappBusiness.config({
      accessToken: process.env.WA_TOKEN!,
      phoneNumberId: process.env.WA_NUMBER_ID!,
      appSecret: process.env.WA_SECRET!,
    }),
  ],
});

for await (const [space, message] of app.messages) {
  if (message.content.type === "text") {
    await message.reply(`Got it: ${message.content.text}`);
  }
}
```
