Segment export: with Facebook Custom Anonymous Audience to Facebook Pixel



Facebook Custom Anonymous Audience destination needs to be set by the administrator (Meiro team).


Learn more about how to set Facebook Custom Anonymous Audience in Meiro Events, Meiro Integrations, and Meiro Business Explorer.


Export  audiences segmented in Meiro Business Explorer to Facebook Business Manager (Meta Business Suite), then to  Facebook Pixels. Create custom anonymous audiences from Facebook Pixels to target audiences further through Facebook Ads. Check the results of your campaign back in Meiro (segment customers you sent the campaign to and check its insights and customer profiles).

Export to Facebook Pixels in Business Manager (Meta Business Suite)

Exports tab setting


Exportable shows how many customers will be exported to your destination.

This number is defined by the conditions you choose to segment the audience but also by mandatory attributes that have been set up by the administrator (that must be present to export to your destination).

For example, if you segment 1000 profiles but only 10 profiles have mandatory attributes present, only those 10 will be exported to your destination.

Mandatory attributes are visible in the Data tab/ Sources & Destinations tab.


For exports to Facebook Pixels, the mandatory attribute is: “Fbp cookie id”.


Customers who we do not know “Fbp cookie id” for, will not be exported to Facebook PIxel.



Audience Name (required)

Audience name inserted here, will be visible in the Facebook Business Manager (Meta Business Suite)/ Facebook Pixel section described below in point 4.

Remember: "Audience name" from Facebook PIxel, will be referred to when setting up audiences in the Audiences section of Facebook Business Manager described below.

Warning: "Audience name" in the context of Facebook Pixel is different from "Audience name" in Facebook audiences. In Facebook Pixel it is visible in the URL address visible above, in the Facebook Audiences, it refers to the name of the audience.

How long does matching between exports from Meiro and Facebook take?

Depending on the size of the exported audience, matching can take anything between minutes to single digit hours. 

Update with the interface of Facebook can take 2-3- days though. 

In case of doubt, please check with the Meiro team. 

Will Facebook Audience be updated automatically when I schedule export on a regular basis from Meiro to Facebook Pixel? Yes, the audience created from Facebook PIxel should be updated automatically by Facebook. 
Will upload of the events be incremental or overwrite existing audiences?

Load of the events is incremental to the same "segment ID". Please note that the cookie will be in the Facebook Ads Audience for the number of days defined while creating the audience in Facebook since the last event sent for this cookie.
