Notifications
Learn how to set up and use notifications in TanStarter
TanStarter supports sending notifications when users successfully complete a payment. This allows your team to receive real-time order alerts in their tools.
Currently Discord and Feishu are supported as notification channels. You can add more channels by implementing the NotificationProvider interface.
Setup
Enable Notification Channel
Configure the notification provider in src/config/website.ts:
export const websiteConfig: WebsiteConfig = {
// ...other config
notification: {
enable: true,
provider: 'discord', // or 'feishu'
},
// ...other config
}Configure Webhook URL
Based on the notification channel you selected, configure the corresponding Webhook URL:
- Go to your Discord server and open the channel where you want to receive notifications
- Click the gear icon to open
Channel Settings - Select
Integrations>Webhooks>New Webhook - Set a name and avatar for the webhook (optional)
- Copy the
Webhook URLand add it to your.envfile:
DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/..."- Go to your Feishu group chat
- Click the group name >
Group Settings>Bot Management - Add a new
Custom Botand enableWebhooks - Copy the generated
Webhook URLand add it to your.envfile:
FEISHU_WEBHOOK_URL="https://open.feishu.cn/open-apis/bot/v2/hook/..."If you are setting up your environment, you can now go back to the Environment Configuration and continue. The rest of this document can be read later.

Notification Message Examples
Discord Message
Discord notifications are sent as messages with green color and structured fields for easy reading.

Feishu Message
Feishu notifications are sent as plain text messages with all purchase information clearly displayed.

Extending New Notification Channels
TanStarter supports extending with new notification channels:
- Create a new file in the
src/notification/providerdirectory (e.g.,slack.ts). - Implement the
NotificationProviderinterface:
import type {
NotificationProvider,
SendPaymentNotificationParams,
} from '../types';
export class SlackProvider implements NotificationProvider {
private webhookUrl: string;
constructor() {
const webhookUrl = process.env.SLACK_WEBHOOK_URL;
if (!webhookUrl) throw new Error('SLACK_WEBHOOK_URL is required.');
this.webhookUrl = webhookUrl;
}
getProviderName(): string {
return 'slack';
}
async sendPaymentNotification(
params: SendPaymentNotificationParams
): Promise<void> {
const { sessionId, customerId, userName, amount } = params;
try {
// Your Slack message implementation
await fetch(this.webhookUrl, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
text: `đ New Purchase\nUsername: ${userName}\nAmount: $${amount.toFixed(2)}`,
}),
});
} catch (error) {
console.error('Failed to send Slack notification:', error);
}
}
}- Register the new provider in the
providerRegistryinindex.ts:
import { SlackProvider } from './provider/slack';
const providerRegistry: Record<NotificationProviderName, ProviderFactory> = {
discord: () => new DiscordProvider(),
feishu: () => new FeishuProvider(),
slack: () => new SlackProvider(),
};- Select the new provider in
websiteConfig:
notification: {
enable: true,
provider: 'slack',
},References
