FAQ and Troubleshooting

Since the Messenger bots integrate with Facebook, there is some setup and troubleshooting required on your own Facebook page.

Character Limit

The character limit for messages is 2k characters

My bot is not responsive - Renew Facebook Token

Facebook requires you to update the token every couple of months. The tokens have to be manually updated. 

To renew the token, you just have to link the bot again to the Messenger Channel (doing the login in Facebook, if required again).

Click on CONFIRM to save the channel, refresh the page and run another test.

This process automatically renews the token, and it's always the first thing to try when the sending/reception fails! 

"There is no Facebook Page" error when connecting your page:

This error may occur when the Facebook page's account you're trying to link does not have the expected permissions to integrate with our app.

This is resolved by making sure the Facebook profile you're trying to log in with has full Facebook access permissions inside the settings of your FB page.

To check this, please make sure you are inside the FB page and follow these steps:

  1. Click on the avatar of your FB page on the upper right corner > Settings and Privacy
  2. Inside Settings & Privacy click on Settings
  3. Inside the Settings section, if you scroll down in the left menu, you will find the Audience and visibility section and there you will need to click on Page setup
  1. Inside the Page setup section click on Page access
  1. Under the People with Facebook access section, you will need to see yourself there, if you don't see your FB profile, then you need to add yourself by clicking on Add New
You will need to find your Facebook profile among the list of all the people in Facebook who have the same name. If it's not possible to find yourself, try finding a colleague who also can have permission for the account so they can do the add the FB channel inside Landbot.

You can check your user's permissions for your Facebook pages following the instructions of this Meta guide.

How can I see other Facebook Pages to connect to my bot?

If you are not being able to see the Facebook page you want to integrate with Landbot, you must update your Business Integrations set up in your Facebook account. To do so, please:

  1. Access your Facebook account and click on your avatar > Settings & Privacy > Settings
  2. Click on the option Business integrations:
  3. Click on View and Edit in the Landbot integration.
  4. Enable (turn on) all options, or choose the ones you want to show, and save.
  5. Refresh the page in Facebook and Landbot, and create a new Messenger Channel in Landbot.

Can I link the same Facebook page to multiple bots?

❌ No. You can have just a bot active on your Facebook page at the same time.

✅ Of course, you can change the bot at any time from the Linked Bot section, as we've seen before.

Can I create multiple channels with the same Facebook page?

❌ No, you can't create multiple Messenger channels with the same Facebook page. If you try to do this, you'll get this error:

✅ What you can do is have multiple channels, each from different Facebook pages (from the same Facebook account).

Can I have more than one Facebook account integrated with Landbot?

Yes, you can have more than one Facebook account, just keep in mind that you must follow all the steps to create a Facebook Messenger Channel and be logged in to your other Facebook account (must have Admin permissions for the Facebook Page) within the same browser window.

Can I send a proactive message to open the chat?

It is possible to do this in the setup of your Facebook Page.

Go to the page Settings > Choose Messaging from the left side Menu > Starting a Messenger Conversation > turn the option "show a greeting" ON > Customize the message.

Can I send or receive voice notes?

In fact, this is a limitation of the integration, even though your users send voice notes, you will not be able to see or hear them in the Chats section or in the Analyze or Metrics section 👆🏻

Can I automatically save the username?

No, in order to have the user’s name you have to ask it and save it under a variable e.i. @name
