Na Prestashop 1.6 y sme potrebovali implementovať FB conversion API tracking
The server-side API lets you send web events data to Facebook directly from your server. You'll need to generate an access token to use the API.
1. Generate an access token
You need an access token to implement the server-side API. Generate your access token and keep it somewhere safe. To help protect your security, Facebook will not save your access token. You'll use this access token to make calls to the API. You'll need admin access to Richard Medňanský's business account to generate an access token. Access token nájdete v prílohe.
2. Follow instructions for API implementation
Follow instructions for implementing the server-side API on the Facebook for Developers site.
TU je aj návod z facebook for developers pre implementáciu: https://developers.facebook.com/docs/marketing-api/conversions-api
