Are you struggling to understand why your Facebook Messenger bot is connected to your page but displaying an empty subscription list? You’re not alone! This frustrating issue has puzzled many developers, and today, we’re going to dive deep into the world of Facebook Messenger bots to uncover the root causes and provide a step-by-step guide to resolve this problem.
What is a Facebook Messenger Bot, and How Does it Work?
Before we dive into the meat of the issue, let’s take a quick look at how Facebook Messenger bots work. A Facebook Messenger bot is a software that uses artificial intelligence to automatically respond to user messages. Bots can be used for various purposes, such as customer support, marketing, or even entertainment.
To create a Facebook Messenger bot, you need to:
- Create a Facebook Page
- Set up a Facebook Developer Account
- Create a new Facebook App
- Subscribe to the Facebook Messenger Platform
- Configure your bot using the Facebook Messenger Platform API
Why is My Facebook Messenger Bot Connected to My Page but Showing an Empty Subscription List?
Now that we’ve covered the basics, let’s explore the possible reasons why your Facebook Messenger bot is connected to your page but displaying an empty subscription list:
- Invalid or Missing Subscription URL: The subscription URL is the endpoint that receives updates about user interactions with your bot. If this URL is incorrectly configured or missing, your bot won’t receive subscription updates.
- Incorrect Webhook Setup: Webhooks are used to receive updates from Facebook about user interactions with your bot. If the webhook is not set up correctly, your bot won’t receive subscription updates.
- Facebook App Review Status: If your Facebook App is still in the review process or has been rejected, your bot won’t be able to receive subscription updates.
- Page and App Connection Issues: If the connection between your Facebook Page and App is not correctly configured, your bot won’t be able to receive subscription updates.
- Token and Authentication Issues: If the token used to authenticate your bot with the Facebook Messenger Platform is invalid or expired, your bot won’t be able to receive subscription updates.
Step-by-Step Guide to Resolve the Issue
Now that we’ve covered the possible reasons, let’s take a closer look at the step-by-step process to resolve the issue:
Step 1: Verify Subscription URL and Webhook Configuration
Log in to your Facebook Developer Account and navigate to your Facebook App. Click on “Messenger” and then “Webhooks”. Verify that the subscription URL and webhook are correctly configured.
curl -X POST \
https://graph.facebook.com/v13.0/me/subscriptions \
-H 'Authorization: Bearer YOUR_PAGE_ACCESS_TOKEN' \
-H 'Content-Type: application/json' \
-d '{"subscribed_fields":["messages"]}'
Step 2: Check Facebook App Review Status
Log in to your Facebook Developer Account and navigate to your Facebook App. Click on “App Review” and check the status of your app. If your app is still in the review process or has been rejected, resolve the issues and resubmit your app for review.
Step 3: Verify Page and App Connection
Log in to your Facebook Page and navigate to ” Settings” > “Advanced” > “Messenger Platform”. Verify that your Facebook App is correctly connected to your Page.
Step 4: Verify Token and Authentication
Verify that the token used to authenticate your bot with the Facebook Messenger Platform is valid and not expired. You can use the Facebook Access Token Debugger to verify the token.
curl -X GET \
https://graph.facebook.com/v13.0/debugToken \
-H 'Authorization: Bearer YOUR_PAGE_ACCESS_TOKEN' \
-H 'Content-Type: application/json'
