Prestashop facebook pixel meta tag

[ComGrafPL]

I have connected prestashop to facebook pixel.

Its on an active on FB. Want it to export products list from presta to FB store.  Did all things correctly.

1. Pixel connected - but its gray, saying Not Ready

2. Export CSV  - Pixel did not find any products

3. Option on Pixel to check product link to find whats wrong -   "Microdata Tags " Products from the site cannot be automatically added to the catalog due to the problems listed below:

"A required field is missing: id

Products without "id" information can't be uploaded. Please check that this field is included for each product in a separate, labeled column."

How to fix it? Any workaround to add that specific microdata, that facebook could verify.

I know i need to add Open Graph, Schema.org tags but no idea how to do it.

 

PS: Im using Presta 1.7.5.2
