Facebook Marketplace actively blocks third-party form automation, so SyncList does not auto-fill or auto-publish Facebook listings. Instead, you publish to Facebook yourself, and SyncList tracks each listing in your inventory dashboard alongside Etsy, Depop, Mercari, and Poshmark — so you have a single source of truth for what's live where.
The dashboard treats Facebook as a tracked destination. The extension watches for a published Facebook Marketplace listing in your selling hub and captures the listing URL so it shows up next to your other marketplaces.
Facebook's listing form is one of the most aggressively-protected against third-party automation on the web. The form is gated behind dynamic React components, rate-limited interactions, and active fingerprinting that flags accounts which behave like automation. Tools that promise "Facebook auto-fill" tend to either get accounts limited or break on every Facebook redesign.
We'd rather under-promise and over-deliver. Auto-fill is on the roadmap for when Facebook opens an official creation API, but in the meantime your time is better spent typing on Facebook for two minutes than getting your seller account flagged.
