Hi Grégoire
There isn’t a direct filter or hook in the Facebook for WooCommerce plugin that would allow you to hide the price when a product is shared from Instagram. Facebook for WooCommerce is designed to sync your product information from WooCommerce to Facebook, including product details, descriptions, and prices.
However, in addition to hiring a developer, there’s a workaround that you might consider. You could use a plugin to conditionally hide prices based on certain parameters. There are several plugins available that can help with this, such as the WooCommerce Hide Price & Add to Cart Button plugin.
You can set up conditions to hide the price for certain users, products, or categories. This is not a perfect solution as the price will be hidden in your WooCommerce store and not just on Instagram, but it may serve your client’s needs.
