# Managing Meta Messenger Referrals in Flow Builder

Meta [Messaging Referrals](https://developers.messagebird.com/quickstarts/facebook/referrals/) are specific **inbound**-**only** messages that are triggered once your end-user:

* Clicks on an [m.me link with a referral parameter](https://developers.facebook.com/docs/messenger-platform/discovery/m-me-links)
* Clicks on a [Facebook Messenger conversation advertisement](https://developers.facebook.com/docs/messenger-platform/discovery/ctm-ads)
* Starts or resumes a conversation thread from the [Facebook Chat Plugin](https://developers.facebook.com/docs/messenger-platform/discovery/facebook-chat-plugin)

The rich automation capabilities of Flow Builder enable you to create a Flow scenario, depending on your use case, of how you want to handle these inbound messages.\
Let's say you have created a [Facebook Messenger conversation advertisement](https://developers.facebook.com/docs/messenger-platform/discovery/ctm-ads) with a *Get Started* call to action, initiating a Messenger conversation:

1\) Create a new [Flow](https://dashboard.messagebird.com/en/flow-builder/create/custom), with the Facebook Messenger incoming message as the trigger:

2\) Choose the Messenger channel you have [set up](https://dashboard.messagebird.com/en/channels) to start the Flow:

3\) Create the desired automation scenario of the Flow, be it replying to the end-users message via a customized chatbot Flow, collecting inputs into an external [Google Sheet](/connectivity-platform/basics/flowbuilder-steps-glossary.md#01g1jen5k3hqacptnejekwb75t), or managing the conversation in [Inbox](https://inbox.messagebird.com/).

#### Messenger Referrals Variables <a href="#id-01g6x1fd6xz0fneqbncjbqxdx2" id="id-01g6x1fd6xz0fneqbncjbqxdx2"></a>

Meta [Messaging Referrals](https://developers.messagebird.com/quickstarts/facebook/referrals/) have a set of variables that can be exploited in Flow Builder. Variables starting with:<br>

* `conversationMessageFacebookReferral` correspond to messages from [m.me link with a referral parameter](https://developers.facebook.com/docs/messenger-platform/discovery/m-me-links) and [Facebook Chat Plugin](https://developers.facebook.com/docs/messenger-platform/discovery/facebook-chat-plugin)
* `conversationMessageFacebookReferralAd` relate to values populated when end-users click on call to action on Facebook Ads.<br>
