How to Stop a WhatsApp Bot from Sending Duplicate Replies in XpressBot
Why Does the Duplicate Reply Issue Happen?
The primary reason for duplicate replies is the setup of multiple Facebook apps with the same webhook URL. Here’s a breakdown of how this happens:
- Many users who set up WhatsApp bots for multiple phone numbers create separate Facebook apps for each number.
- They configure the same webhook URL across multiple apps.
- When a message is sent to the bot, the webhook is triggered multiple times—once for each app using the same URL. This results in duplicate replies being sent to the user.
Other Possible Causes of Duplicate Replies:
Apart from multiple Facebook apps, other factors can contribute to duplicate replies:
- Delayed Webhook Responses: If the webhook response time is slow, WhatsApp may retry the request, leading to duplicate replies.
- Bot Logic Issues: If your bot is not optimized, it might process the same message multiple times.
- Redundant API Calls: If your bot sends multiple API requests for the same message, it could generate duplicate responses.
In summary, the issue often arises when multiple webhook activations occur due to misconfigurations or redundant setups.
How to Prevent Duplicate Replies
The best way to prevent duplicate replies is to avoid creating multiple Facebook apps for each WhatsApp Business number. Instead, use a single Facebook app and manage multiple numbers under it.
Why This Works:
- WhatsApp Business API allows multiple numbers under one Facebook app, eliminating the need for separate apps.
- With a single app, you only need one webhook URL, preventing multiple activations and duplicate replies.
- XpressBot works best when configured with a single, properly optimized webhook setup.
Steps to Add Multiple Numbers to a Single Facebook App:
- Log in to your Facebook Developer account and access your app.
- Navigate to WhatsApp Settings and add additional phone numbers under the same app.
- Verify that only one webhook URL is configured for this app.
- Test your bot with different phone numbers to ensure it responds correctly.
By following these steps, you can prevent duplicate reply issues and keep your bot running smoothly.
What If You’re Already Facing Duplicate Replies?
If your bot is already sending duplicate responses, here’s how to fix it:
1. Check for Multiple Facebook Apps:
- Log in to Facebook Developer and review your created apps.
- Identify whether multiple apps are using the same webhook URL.
2. Remove Redundant Webhooks:
- Choose one primary app for your bot.
- Remove the webhook URL from all other apps to ensure only one app triggers responses.
3. Optimize Your Bot Logic:
- Ensure your bot processes each incoming message only once.
- Implement message deduplication to filter out repeated requests.
4. Test Your Bot:
- After making changes, test your bot by sending messages to confirm the issue is resolved.
What If the Issue Still Persists?
If you’ve followed these steps and still experience duplicate replies, consider these additional troubleshooting steps:
- Check API Logs: Analyze logs to see if duplicate responses are triggered.
- Monitor Webhook Responses: Ensure your webhook response time is fast enough to prevent WhatsApp from retrying requests.
- Reach Out to XpressBot Support: If the issue continues, contact XpressBot’s support team or your WhatsApp API provider for assistance.
