For Messenger to work, you need a way for your customers to opt-in to the bot. We recommend using different features based on the status of your Facebook checkbox.
The checkbox can be unchecked and pre-checked:
If you haven't used the Messenger widget before September, 21 2018 your checkbox is most likely unchecked and currently there's not a way to get it pre-checked because of a change in Facebook's policy.
In this case, we recommend you use an alternate method to opt-users in. Here are some options:
- The Discount Pop-up which opts users in on a pop-up on your site. If they click the button to receive a discount they will be opted in.
- The Customer Chat Widget which embeds the bot directly on your site. If customers start chatting with the bot, they will be opted-in.
- Create custom calls to action with our Website capture tool.
If you used Messenger widget before September, 21 2018 your checkbox might be pre-checked, in which case, you are eligible to use the add to cart checkbox to send abandoned cart messages. That will trigger a Facebook message every time someone abandons a cart without unchecking that box.
