Hi Marcelo,

Thanks for your questions.

"1. In the reports. Is it possible to use FB Custom Conversions?"
In case you set a custom conversion for any of your Facebook Ads campaigns it will be the data that we will show at the report

"2. Why should we create the FB campaigns straight from your platform instead of FB Business Manager?"
The main advantages are that we use the data of your social networks to recomend you segmentation, keywords and content for the campaign. Also you can create at the same time a campaign in Google Ads, saving time and using the same settings for both platforms.

The integration of all this social and ad platforms, allows you to create your digital marketing campaing in a single place using your one metrics saving time and improving your perfomance.
