Make sure your bot is connected to your Facebook page. Here’s a guide on Publishing your bot.
If you’re using the Free version of Chatfuel - make sure you’re not over the limit of reachable users allowed on your plan (up to 50 users). You can check that by going into the Analyze tab or the People tab
3. If your bot is connected to the page, and you’re not over your reachable users limit - try reconnecting the page. You can do this in the Grow tab of your bot, by clicking on the “Disconnect” button, and then connecting the bot to the page again.
If you have trouble reconnecting the bot, it can easily be a permissions issue. You'll be able to resolve it by removing Chatfuel from your Business Integrations and Facebook Apps.
After this, first delete the conversation with the bot from your personal inbox and then start over in order to test the bot.
4. Are all of your Flow elements valid? If you're using Entry Points, make sure these are turned on and valid. This is what a correctly turned on Entry Point looks like.
Make sure that all the options in your Entry Point are connected to a valid block. If one of the options doesn't have a destination, the Entry Point won't be valid. Any errors will be easy to spot since they'll be outlined in red.
If everything is connected correctly and valid, you can also try toggling the Entry Point off and then on again.
5. If your bot is still not responding, it’s possible that there is an app conflicting with Chatfuel. First make sure that Facebook’s default responses are turned off in your page’s messenger. If that’s in order, then go into your Facebook page’s Settings → Advanced Messaging and check if there is an app conflicting with Chatfuel. If you are not using Facebook's Handover Protocol (in combination with Chatfuel's Conversation Handover plugin), then there should be no apps selected as the Primary or Secondary Receiver.
If you’ve followed all the steps, and your bot still doesn’t seem to be responsive, please notify the support team and we’ll make sure to help out. You can do that through the chat bubble in the bottom right corner of this window, or by emailing email@example.com
