Understanding Instagram Comment Webhook Issues: Troubleshooting Challenges for WordPress Integrations

If you’re managing a WordPress-based website that integrates with Instagram’s API, you’ve likely encountered scenarios where real-time comment notifications are crucial for your application’s functionality. Recently, many developers and content managers have reported intermittent issues with Instagram’s comment webhooks—particularly when trying to monitor comments on newly published posts.

The Challenge: Webhook Interruptions on New Posts

Many users have observed that initially, their webhooks for comment notifications functioned perfectly, capturing comments on all posts, including recent ones. However, over time, the webhook’s reliability diminishes; comments on new posts stop triggering notifications, while older posts continue to send updates without issue. Interestingly, after some hours or days, comment webhooks on new posts resume normal operation before faltering again.

What Has Been Tried?

Developers have experimented with several solutions, including:

• Updating the webhook callback URL to different paths
• Removing and re-establishing webhook subscriptions
• Testing the webhook endpoint directly via development portals, which often reports no errors

Despite these efforts, the problem persists: comments on fresh posts are no longer sent via the webhook, even though older posts continue to report comments seamlessly.

Potential Causes and Troubleshooting Tips

While the root cause remains elusive for many, here are some insights and best practices to consider:

1. Webhook Subscription Limits: Ensure that your webhook subscription hasn’t reached any platform-imposed limits or quotas, which might restrict new subscriptions or notifications.

2. Instagram API Changes: Instagram often updates its API and webhook behavior. Regularly check official documentation for recent changes that might affect webhook subscriptions and event delivery.

3. Post Privacy and Content: Confirm that the posts in question meet all criteria (public visibility, proper permissions) required for the webhook to trigger.

4. Webhook Endpoint Reliability: Verify that your server handling webhook requests maintains a high uptime and responds within Instagram’s expected time frame. Even minor delays or downtime can cause Instagram to stop sending notifications.

5. Check Subscription Status: Use the Instagram Graph API tools to verify that your webhook subscriptions are active and correctly configured for all relevant fields.

6. Rate Limiting and Filtering: Larger accounts or high comment volumes may trigger rate limiting or filtering rules that suppress certain notifications.

7. Debugging and Logging: Implement detailed logging on your webhook endpoint to catch and diagnose incoming requests and potential errors.
